Abstract

Neighbourhood effects studies typically investigate the negative effects on individual outcomes of living in areas with concentrated poverty. The literature rarely pays attention to the potential beneficial effects of living in areas with concentrated affluence. This poverty paradigm might hinder our understanding of spatial context effects. Our paper uses individual geocoded data from the Netherlands to compare the effects of exposure to neighbourhood affluence and poverty on educational attainment within the same statistical models. Using bespoke neighbourhoods, we create individual neighbourhood histories which allow us to distinguish exposure effects from early childhood and adolescence. We follow an entire cohort born in 1995 and we measure their educational level in 2018. The results show that, in the Netherlands, neighbourhood affluence has a stronger effect on educational attainment than neighbourhood poverty for all the time periods studied. Additionally, interactions with parental education indicate that children with higher educated parents are not affected by neighbourhood poverty. These results highlight the need for more studies on the effects of concentrated affluence and can inspire anti-segregation policies.

Introduction

The current interest in the economic impacts of neighbourhood effects was ignited by W.J. Wilson’s book The Truly Disadvantaged [1]. The field has been dominated by a “poverty paradigm” ever since [2] as studies on a wide range of individual outcomes focussed almost exclusively on the presumed negative effects of living in poverty concentration neighbourhoods. The research focus on poorer neighbourhoods is understandable, as these are the places where a variety of problems accumulate and restrict individual life chances. Moreover, poor neighbourhoods are highly relevant from the perspective of public policy interventions aimed at reducing poverty and related problems. However, focusing solely on the negative effects of spatially concentrated poverty may hinder our understanding of the role of spatial context effects in individual life courses. Studying the effects of living in areas with concentrated affluence could help us to better understand how inequalities arise. After all, the Matthew effect suggests that not only do the “poor get poorer”, but also that the “rich get richer” [3].

Few studies have specifically investigated the effects of living in affluent neighbourhoods on individual outcomes [4], despite repeated calls to do so since the 1990s [5, 6]. The lack of literature on concentrated affluence is even more striking given the influential position of affluent households: the choices of the wealthy largely shape patterns of socio-economic segregation in cities, as higher income households can use their resources to select the best residential locations in a city [7]. By using their wealth, richer residents are able to [re]produce spatial inequalities, including the inequalities arising from both positive and negative neighbourhood effects [8].

To ameliorate negative neighbourhood effects, policy has often focused on the social renewal of poor neighbourhoods through relocating poor and introducing more affluent households–a policy without substantial empirical support [9]. The need to focus on tackling concentrated poverty while neglecting the spatial concentration of richer households has likely contributed to that limited policy approach [10]. Ultimately, the overwhelming focus on “fixing” poverty could, in part, be the result of researchers adopting theories based on individual social actors’ attributes rather than on a more dynamic view of society, in which upper social classes manage their resources through mechanisms of exploitation and exclusion (see the overview of social inequality theories in [11]).

There is a small number of studies that have demonstrated the significant influence of elite or affluent spatial contexts on various life outcomes in Europe [4, 1216] and in North America [1719]. Amongst the important findings from these papers is that well-off and more highly educated neighbours can transfer their social and cultural capital through shared social networks formed within the neighbourhood. This is of particular importance for children’s educational outcomes, considering that richer and more highly educated neighbours not only promote ambitious social attitudes (attending university to access high paying jobs as a norm), as well as invest in local community initiatives out of interest in the wellbeing of their own offspring [20]. Wealthier residents are likely to set higher standards for extracurricular activities for local children, spending time and resources on activities related to sport or culture. Through participating in such activities, children and teenagers not only expand their objective skills and knowledge, but also learn social codes which can be important for accessing affluent settings [21]. Evidence from the Netherlands also suggests that homogenous high-income neighbourhoods exhibit more local solidarity behaviours than poorer or mixed-income neighbourhoods [22].

This study investigates the effects of exposure to neighbourhood affluence and neighbourhood poverty on educational attainment, using data from the Netherlands. Although by international standards Dutch cities are only moderately economically segregated, there is evidence of growing socioeconomic inequality in recent years [23], as well as isolated elite spatial contexts, created by rich households seeking to further accumulate their capital [24]. Moreover, the Dutch educational system is highly stratified and shows a growing dependency on students’ socioeconomic background [25]. In our study we use longitudinal register data, which enable us to follow the 1995 birth cohort and construct neighbourhood histories from birth to age 18, and measure educational outcomes at age 23. We study the effects of exposure to affluence and poverty at different stages of development: early childhood (ages 0 to 12), adolescence (13 to 17) and the entire childhood (0 to 17). The measures of neighbourhood poverty and affluence are created from bespoke neighbourhoods based on the nearest 200 households. Following earlier studies [20], we also test if the exposure to the neighbourhood context (both affluence and poverty) is different for children with different parental levels of education. We find that, in all models, neighbourhood affluence has a stronger effect on educational attainment than neighbourhood poverty. Additionally, interactions with parental education indicate that children with higher educated parents are not affected by neighbourhood poverty.

Theoretical background

The spatial influence of affluence

The neighbourhood context can influence educational outcomes of a child, similarly to the effect of parental and school factors, with which neighbourhood factors often interact [12]. The literature focusses mostly on social mechanisms [26] in the neighbourhood, including social interactions, which are based on physical proximity. The benefits of affluence for the quality of the built environment and facilities such as libraries, or schools, are clear–richer parents will have more resources to invest in their community, which they first carefully chose according to their preferences [27]. However, the social networks formed in the neighbourhood, which can be of high importance for children’s future [4, 15], are also affected by the wealth of local inhabitants.

Much of the neighbourhood effects literature uses the theory of resource transmission through local networks, which in turn is based on Bourdieu’s concepts of social and cultural capital [28]. By knowing certain types of people (social capital), individuals gain access to valuable information about schools or jobs, as well as adopt certain habits and ways of expression which lead to being accepted by those in charge of school or job admission (cultural capital). Yet even when individuals are in possession of these skills and attitudes, these paths may remain untrodden if, for example, they do not perceive attending a university as a realistic option for their future. These socially inspired possibilities are covered by the concept of habitus [29]. The life choices individuals make must fit in within their habitus, which is formed by those with whom they are interacting [30]. As individuals imitate others during their socialisation, the way they perceive the world and their place within it is shaped by their socioeconomic background. The habitus of a social class influences children’s attitude to institutions [31]: the poorer parents, family members and classmates are unable to mobilise the same degree of social and cultural capital while dealing with authorities as richer ones.

Households reproduce neighbourhood characteristics by choosing neighbourhoods with people who are like themselves, and this is partly driven by their choice of housing and the neighbourhoods in which it is available [32]. Even if they are not consciously aware of social mechanisms, resourceful parents are likely to choose a neighbourhood as affluent as possible and contribute to preserving or enhancing that status [4]. Such behaviour is rationalised as a desire to provide their children with a safe environment and protect from possible disorder in other neighbourhoods rather than to seek the positive effect of affluent ones [33]. For children, a safe environment is important because they spend time with their peers outside both in early childhood and in adolescence, playing sports and games. Unsupervised play outside is less prevalent among richer children, but still present [34]. For a child from a poorer household, becoming part of a social network with children from more affluent households can result in peer effects overriding the educational and vocational preferences of their own parents [4]. Shared behaviours, such as studying together (potentially supervised or assisted by higher educated parents) or refraining from skipping class, contribute further to educational success. Parents themselves may also be affected by the parenting attitudes in the neighbourhood [20]. Neighbourhood networks are often connected to other networks, for example when local children are encouraged to join clubs playing higher status sports such as field hockey or tennis [34]. Ultimately, a transmission of resources takes place in richer neighbourhoods, and children from poorer households can benefit from residing in such places.

Neighbourhood poverty in European context

Poorer neighbourhoods are not only deprived of resources, but also must deal with a wide range of consequences of poverty, including higher crime rates or the social isolation of migrant groups. Many studies of neighbourhood context influencing educational attainment from the US have focused on such spatial disorder, with participants expressing the stress caused by presence of organised crime or drug trade [35, 36]. However, these issues are less prevalent in the more egalitarian European societies [37], with higher government spending on welfare [38]. There are also differences between Northern American and European urban planning, with European cities being more “urban”–denser, with well-developed public transit networks–while many American cities are characterised by extensive, car-oriented, suburbs [38]. Even if Western European cities have also experienced suburbanisation during the last decades [39], their more compact nature should result in lower spatial isolation experienced by their inhabitants. Furthermore, cities in the US have been expanding due to international migration, a phenomenon which remains much slower in Western Europe [38]. The large influx of new inhabitants from abroad may make social cohesion in American cities more difficult to achieve.

These differences between European and American cities might be a reason for caution in using US studies as inspiration for research on European data. The strong focus on poverty could be one of such trends. Even if American authors have long been calling for a greater focus on affluence [5, 6], most of the US research and public attention goes to deprived neighbourhoods [2]. Based on the practical reality of relatively egalitarian Western European cities, we assume that in the Netherlands, the lack of higher educated, affluent neighbours could be more important than the overall impact of poverty. This assumption is further supported by the few studies from European countries which show that the influence of neighbourhood affluence on various outcomes can be stronger than that of neighbourhood poverty [13, 14].

While comparing the effects of affluence and poverty, it is important to highlight that one is not simply the inverse of the other. As already discussed, poverty is often associated with crime and isolation of minority groups [35, 36]. Furthermore, the accumulation of different types of capital characteristic for affluence could progress at very different rates than the negative effects of poverty, which can also accumulate (for example, having debts can lead to difficulties in finding an affordable mortgage). There are studies which not only show that the effect of one could be stronger than the other, but also that there can be a significant effect of concentrated affluence on health while concentrated poverty has no effect at all [19]. Affluence and poverty can also interact differently with individual characteristics. This lack of symmetry is an argument for including them both in empirical models, as well as measuring them as distinct and separate factors to capture all of their influence. There are also theoretical reasons for studying poverty together with affluence, while using the Weberian-inspired conceptualisations of social and cultural capital, on which we elaborate in the next section.

Conceptualising social inequality

This paper addresses the issue of the poverty paradigm in the literature by specifically paying attention to spatially concentrated affluence. Understanding social inequality is central in research on neighbourhood effects, as social inequality is both their cause and consequence. It is, therefore, surprising that there has been relatively little attention paid to the theorising and conceptualising social inequality itself within the field, even in the studies which do include measures of affluence. In the following sections we argue for the need of studying not only the effects of poverty, but also affluence, arising from the theories of inequality used (sometimes only implicitly) in the field.

Most of the quantitative neighbourhood effects research, including the papers discussed in the sections above, fits well into the so-called middle-range sociology, a scientific scope advocated by scientists such as Merton [40] and Boudon [41]. Middle-range sociology is situated between the grand theories and pure empiricism, with theories focused on specific aspects of social life, instead of the whole society; it aims to identify the same social mechanisms in different situations [42]. Middle-range social research papers focus on answering specific research questions based on, most often, quantitative methods such as statistical models or experiments [43]. Studies of neighbourhood effects often investigate specific mechanisms [26], related to the effect of some form of segregation and therefore social inequality in urban space. The strict paper structure characteristic for the middle-range social studies usually does not allow for extensive theoretical commentary about inequality. Nevertheless, the concepts used in these papers are based on a variety of competing approaches to class, status and inequality (for an early overview see [44]), even if these inspirations are not immediately visible.

To understand why researchers tend to overlook the spatial effects of affluence, it is important to highlight some of the traditions in studies of social inequalities and how they relate to the neighbourhood effects field. Wright [11] outlines three main theoretical approaches within the sociology of class, social mobility and inequality: the individual-attributes approach (used in stratification research), opportunity hoarding (the Weberian approach), and mechanisms of domination and exploitation (the Marxist approach).

The individual-attributes approach focuses on how people obtain resources that allow them to attain a certain occupation, and therefore a position within the social strata. These meritocratic resources (for example, education or motivation), combined with attributes people are born with, shape their chances in life. The opportunity hoarding approach begins with the assumption that access to the most prestigious positions tends to be strongly protected–or hoarded–by those already having access. This Weberian approach studies how individuals in the higher social strata distance themselves by setting up requirements based on economic, cultural and social capital, as well as legal mechanisms of exclusion. One example, from urban geography, is when a good school is only accessible to those living in a certain district, and house prices in that area are sufficiently high that only affluent households can afford to live there. The third approach evolves around mechanisms of domination and exploitation. This Marxist approach takes the analysis further, by asserting that those who restrict access to certain resources and positions can also “control the labour of another group to its own advantage” [11]. This approach is present in urban studies research on the exploitations of tenants and ordinary homeowners by landlords and developers, and the pressure the latter can exert on government policies.

Social inequality and neighbourhood effects

Quantitative studies on neighbourhood effects usually mix elements of the individual-attributes and opportunity hoarding approaches. The individual-attributes approach manifests itself as focus on social mobility and the idea that the position an individual ultimately attains is shaped by a bundle of attributes, many of them related to physical space. This approach has the advantage that it is relatively easy to translate into statistical models. However, because of the high level of methodological sophistication in time and space-variant predictors, researchers often reduce their most important status-related neighbourhood characteristic(s) to a single proxy variable which captures the spatial context of an individual.

One approach for measuring the affluence of a spatial context is using income [45]. Using categorical measures, or grouping neighbourhood inhabitants by their income level, often fits the research design better than using average income. Authors tend to follow the tradition of the field by focusing on poverty (choosing to create categories based on the percentage of poor households, etc.), which leads to the relatively lower number of studies on affluence [4]. From the perspective of the individual-attributes approach, this focus on poverty can be justified because there is no assumed relationship between poverty and affluence. As such, “eliminating poverty by improving the relevant attributes of the poor—their education, cultural level, human capital—would in no way harm the affluent” [11]. By contrast, “in the case of opportunity hoarding, the rich are rich in part because the poor are poor, and the things the rich do to maintain their wealth contribute to the disadvantages faced by poor people.” It therefore follows that “moves to eliminate poverty by removing the mechanisms of exclusion would potentially undermine the advantages of the affluent”.

One could argue that a discussion on whether societal well-being can be improved without substantially limiting the choices or wealth of upper strata is not immediately relevant to more exploratory neighbourhood effects research. However, many neighbourhood studies still implicitly use opportunity hoarding theories to explain the mechanisms under investigation. Perhaps Maybe the most important examples are the already discussed concepts of cultural and social capital as developed by Bourdieu [29]. Bourdieu argues that social phenomena such as cultural norms are employed by upper classes to limit the access to their resources. Therefore, researching poverty in isolation disregards, potentially, the most influential part of the picture: the affluent social actors who possess the cultural, social, and economic capital. There are also theories focusing on the spread of disorder associated with capital deficiency, such as the broken windows theory [46]. It could still be illuminating to frame the commonly studied neighbourhood effects mechanisms in terms of the presence of various forms of capital, rather than a lack of it. Those studies investigating the effect of affluence often omit discussion of the wider implications of focussing on the effect of poverty in research. In addition to developing more methodologically sophisticated operationalisations of the current variables, quantitative neighbourhood effects researchers could deepen their assumptions and conclusions by grounding them in sociological theory. This is one of the goals of the current paper, although there are still interesting steps to be taken, such as questioning not only the poverty paradigm, but also the meritocracy paradigm [47] as well as expanding the conceptualisations of social class [48].

Current study

Studies of neighbourhood effects on educational attainment (and in a broader sense all spatial effects studies) should investigate not only the effect of neighbourhood poverty, but also the effects of concentrated affluence. We argued that a better understanding of affluence is crucial for the neighbourhood effects mechanisms driven by various forms of capital. We use household income as a measure of poverty and affluence, which is highly correlated to other, more intangible, characteristics such as social cohesion [49]. Income also serves as a proxy of resources available to neighbourhood inhabitants. Using income allows us to construct detailed individual neighbourhood histories and investigate the effects of different periods of exposure. We also create bespoke neighbourhoods, which reflect local spatial ties better than neighbourhoods based on administrative borders.

Following the literature review, we expect that the positive effect of exposure to affluent neighbours on education attainment will be stronger than the negative effect of exposure to poorer neighbours. We also expect differences between the effects of exposure to contextual poverty and affluence at different developmental stages, but it is not clear from previous work which period of influence will have the greatest impact. For instance, early years childhood exposure could be more influential for educational attainment than later exposures because of values and beliefs formed during the early years. Young children also experience less disruption from changing the neighbourhood environment [50]. However, adolescents have greater freedom from their household and spend more time with their peers away from the parental control, and therefore exposures during adolescence could be more important.

In recent years the focus of neighbourhood effects research has shifted somewhat from “do neighbourhood effects exist?” to “for whom” do they matter [51]. In the case of children, social background could prevent them from interacting with poorer or richer neighbours [4]. Parents can explicitly limit children’s interactions or simply not create any opportunities to play or socialise with children in other groups. On the other hand, children of higher educated parents may be more likely to believe in the importance of education regardless of their peer contacts in the neighbourhood. Given these propositions, we test for interactions between the exposure to neighbourhood affluence or poverty and parental education.

Data & methods

For our empirical analysis we used individual level, geo-coded longitudinal register data from the Statistics Netherland’s Social Statistical Database (SSD), which covers the entire population of the Netherlands. We selected 140,338 individuals born in 1995 who also had complete neighbourhood histories between 1995 and 2017, when they are around 22 years old, and without missing information on the variables of interest (except for parental education, which has a large percentage of missing values). For our dependent variable, education level, we measured the level of education attained by age 23 and translated this in the number of years someone would normally need to achieve that level. We added an extra year for those who studied at research universities (wo) to distinguish them from universities of applied science (hbo). The resulting variable ranges from the minimum of 2 years for unfinished primary education, to a maximum of 23 years required to obtain a doctoral degree, with the mean 16.5 years. For individuals who were still following education in the final year of observation, the level of education that they were following at that time is registered.

The data underlying our results cannot be shared publicly as they are a part of the confidential Statistics Netherlands data. Statistics Netherlands is legally responsible for consent related to data use and they have approved our project. CBS is bound by the European General Data Protection Regulation (GDPR). In addition, CBS adheres to the privacy stipulations in the Statistics Netherlands Act, the European Statistics Code of Practice, and its own Code of conduct [52].

Contextual affluence and poverty

Contextual poverty is measured as a ratio and based on the Eurostat definition of the at-risk-of-poverty rate, which is the share of households with an equivalised disposable household income below 60% of the national median equivalised disposable income. The threshold for contextual affluence is set at 150% of that median, resulting in a similar percentage of the population above this threshold as the percentage of households under the poverty threshold. Even though in our data the detailed household income extends back to 2003, we have sufficient spatial information to people’s residential histories all the way back to 1995, a further 8 years. To overcome the lack of neighbourhood income data pre-2003 we used the averaged neighbourhood income data from 2003 for all years between 1995 and 2002. Although neighbourhood characteristics change over time, using the 2003 data for earlier years is the only way to include the longer time period, which is crucial for our purposes (see [53] on the static nature of neighbourhood positions).

The geocoded nature of our data gives us information on the residential location for each individual at a spatial resolution of 100x100m grid squares. Using this information, we have created bespoke measures of neighbourhood affluence and poverty for each year using Equipop [54]. Equipop calculates the proportion of the k-nearest neighbours that meet user-set criteria, in our case a ratio of the neighbours meeting the poverty or affluence criterion within the 200 nearest households for each year of an individual’s life. These ratios are the building blocks of our neighbourhood history variables, which are described in more detail below. We adjusted the income criterion for the median income in each year: households with an income above 150% of median household income that year were classified as affluent, and those with an income below 60% of median as poor. If, for example, an individual scores 0.15 for their 2005 neighbourhood affluence ratio, this means that in 2005, 15% of the 200 nearest households were regarded as affluent.

By constraining our neighbourhoods to the 200 nearest households, we are able to standardize measures both in densely and sparsely populated areas, important in this study, since we use the data from the whole country. Furthermore, as most of our predictors are based on social interaction, it is appropriate to focus on people rather than space while operationalising the variables.

The scale of spatial research should be chosen according to the theoretical assumptions of the study [55], and in our case we focus on relatively small-scale, social-interactive neighbourhood effects which would happen in neighbourhoods of about 200 households. This size should reflect a social space where people are likely to interact with each other, which, according to the assumptions of this study, assists in acquiring the skills and resources relevant for an individual’s educational attainment.

Exposure to neighbourhood affluence and poverty

We measure exposure to neighbourhood affluence and poverty by combining annual affluence/poverty ratios during different developmental periods: early childhood (ages 0 to 12), adolescence (13 to 17), and the entire childhood (0 to 17): we add up the yearly ratios and divide them by the number of years. The affluence and poverty variables in each period are only weakly correlated (correlation of -.45 for all three periods). We do not include measures of neighbourhood exposure after the age of 17; running models until the age of 23 in an earlier study has shown that young adults have very particular neighbourhood experiences. Many of them leave the parental home around the age 18, moving to cheap student accommodation in often low-income neighbourhoods. That creates a positive effect of having many poor neighbours on attained education, but as the education is rather the cause than the result in such a case, we decided to include only neighbourhood histories up to and including age 17.

Control variables

The control variables in this study include an individual’s sex (female or male) and their ethnicity, which is coded as native Dutch (both parents born in the Netherlands), Western migrant or a non-Western migrant background (Western countries, according to the Statistics Netherlands definition, are all European and Northern American countries along with Japan, Australia and Indonesia). Additionally, an individual’s household context is represented by their household income measured in 2007, when the individual being observed would have been twelve years old, the age by which mothers are likely to have re-joined the labour market, and a variable recording parental education level (lower, middle, higher or missing). The latter variable is constructed by recording the highest education level achieved by either of the (up to) two parents. Parents with missing information on their education are kept in the data as a separate category because of their large number (11% missing) and an overrepresentation of migrants in this category. A control variable at the municipality level is the level of urbanicity, based on the proportion of years between 1999 and 2017 (for which the address density data was available) an individual has lived in an urban environment. To control for the density of social interactions at a lower level, we also included interval distance, measured by Equipop in kilometres necessary to reach the 200 nearest neighbours. The descriptive statistics of all variables can be found in Table 1.

Analytical approach

We estimated a series of linear regression models with educational level at age 23 as the dependent variable. All models are estimated on the same sample of 140,338 individuals, and contain the same control variables. Given the nested structure of our data, the use of multilevel modelling appears logical. However, there are two reasons why we have not used this type of models. Firstly, individuals are nested in neighbourhoods and these can change each year requiring multiple hierarchies which creates a complex structure inhibiting model convergence. This is further exacerbated by the second reason, whereby there is no strict hierarchy because of the multiple membership of individuals in the bespoke neighbourhoods (the neighbourhoods are overlapping with each other). Furthermore, because of bespoke neighbourhoods which are constructed for each individual every year, and only including people born in 1995 in the sample, a large number of individuals are nested alone in their neighbourhood (71,016; 50.60%), which is a further complication in estimating a hierarchical fixed effects structure.

The spatial variables contribute to around 3% difference in R-squared. The initial model without spatial variables explained around 15% (for detailed coefficients, see the S1 Appendix), increasing to 16% when the urbanicity control was added, to 18% with all spatial variables included. This is the magnitude of difference that can be expected from similar variables in sociological models. Additionally, including the spatial variables diminishes the effects of other variables in the model, such as family income, which means the spatial variables contribute to the underlying causal structures. VIF values were unproblematic, therefore there are no issues with multicollinearity in the models (see the S1 Appendix for exact VIF values).

Results

Exposure to neighbourhood affluence and poverty

Table 2 presents the effects of exposure to neighbourhood affluence and poverty over time on educational level (measured in years) at age 23. In the case of affluence, the effects of exposure during the entire childhood (ages 0 to 17) and early years (0–12) are both positive and similar in size (b = 2.138, p < 0.001, beta = 0.133 and b = 2.119, p < 0.001, beta = 0.132, respectively). The effect of exposure to affluence during adolescence remains positive, but is smaller (b = 1.733, p <0.001, beta = 0.118). Compared to early childhood (b = -0.827, p < 0.001, beta = -0.036), the negative effect of exposure to poverty is slightly stronger when taking into account the whole childhood (b = -0.989, p < 0.001, beta = -0.043), and the effect during adolescence (b = -0.925, p < 0.001, beta = -0.052) is the strongest, when looking at the standardised beta coefficient. The most important finding for this paper is the comparison between the effects of affluence and poverty. The modelling results show that exposure to affluent neighbours has a stronger overall effect on educational attainment for all three time periods than exposure to poverty, confirming our hypothesis.

Most of the control variables have the expected effects, with women having a slightly higher levels of education level than men, and with higher parental household income and education being positively related to educational attainment. A surprising effect is that, in our models, Western and non-Western ethnic minorities have a slightly higher educational levels compared to native Dutch individuals. However, our models control both for parental household income and parental education level, which explains much of the negative influence of belonging to a minority ethnic background observed in other studies. In total, each of the models explains almost 18% of the variance in educational attainment.

Interactions with parental education

The effects of exposure to neighbourhood affluence and poverty remain significant in the models which include interactions between these neighbourhood factors and parental education, ranging from lower parental education (reference category), through middle, to higher education, and also including the sizable group of parents whose education level is missing from the data. In the model with interactions with neighbourhood poverty we additionally include the exposure to neighbourhood affluence as a control variable, and vice versa (for detailed results, see the S1 Appendix). For ease of interpretation, we present the results of the interaction terms visually. Fig 1 shows the slopes of the interactions from both models. In the model with the interactions with neighbourhood poverty, children from households with at least one higher educated parent do not appear to be affected by the proportion of poor households in their bespoke neighbourhood. Children of either middle or lower educated parents are negatively impacted, although the severity of the impact is differential. When the proportion of poor neighbours is low then it is the children of lowest educated who are most at risk; the experienced effects are similar for children from lower and middle educated families at the highest proportion of poor neighbours.

Fig 1

In the model with the interactions with neighbourhood affluence, all interaction slopes are positive, although the slope of the interaction between higher parental education and neighbourhood affluence is slightly flatter. This implies that again, children with at least one higher educated parent are less susceptible to their neighbours’ influence on educational attainment, compared to those with lower educated parents. However, this difference is less pronounced in the case of exposure to affluent neighbourhoods than to poor ones.

Conclusions & discussion

In this paper we have compared the effects of exposure to neighbourhood affluence and neighbourhood poverty during different stages of childhood on educational attainment. We argued that there are theoretical reasons to believe that exposure to affluence may actually be more important as a predictor of educational attainment than exposure to poverty, because of the crucial influence of interacting with higher educated people on one’s resources, skills and educational aspirations; and, in the Dutch context, because of the lack of extreme concentrated poverty. Confirming this empirically, our results show that neighbourhood affluence has a stronger effect on educational attainment than neighbourhood poverty in the Netherlands. This is consistently the case across different time periods–from early childhood (ages 0–12), adolescence (13–17)–as well as for the entire childhood (0–17). According to our models the neighbourhood effects during different time periods are similar when it comes to magnitude, direction, and significance. Interestingly, the effect of exposure to poverty during the entire childhood period is stronger than that of shorter periods, which contrasts with previous results from the US [50] and the Netherlands [56].

We considered the educational level of parents to explore whether children from higher or lower educated parents are influenced differently by the neighbourhood. This is in line with earlier works, arguing that neighbourhood effects may not be the same for everybody within the neighbourhood, and that the heterogeneity of individual backgrounds might be important for their transmission [51]. The interactions between the effects of neighbourhood affluence or poverty and parental education level show that children with at least one higher educated parent are not impacted by neighbourhood poverty. We therefore consider higher education to be a buffer against negative neighbourhood contexts. However, children with higher educated parents are still influenced by neighbourhood context when that context is set in affluence, although their gains are not as great as those experience by children living in households with lower levels of parental education.

Most importantly, our results highlight how spatially concentrated affluence contributes to the reproduction of socioeconomic inequalities, as the effect of neighbourhood affluence on educational attainment is stronger than that of neighbourhood poverty. It seems that, in this sense, neighbourhood effects in the Netherlands are similar to those observed in the UK [13] and Finland [14]. Our results, specifically the effect of spatially concentrated affluence being stronger than that of poverty, support our initial idea that it is often the lack of resources–the cultural and economic capital of richer neighbours—in poor and middle-income neighbourhoods that is the problem, not the theorised negative effects of poverty itself. Again, in the Dutch context, crime and teenage delinquency are at relatively low levels compared to the United States, where much of the previous literature is set. Social interactions with resourceful neighbours and peers do seem to play an important role in forming children’s ambitions, as well as in sharing knowledge and forming attitudes that support them. Additionally, children with at least parent with a higher level of education were less susceptible to neighbourhood influences, especially when living in poor neighbourhoods, which suggests that parental resources have a buffering role, compensating for the local lack of capital. Such children were also less affected in affluent neighbourhoods, but they still benefitted from the neighbourhood context. This implies that neighbourhood resources can have an added effect regardless of family background.

One potential possible limitation of this study is that we have measured neighbourhood resources only taking into account household income. While the use of this relatively simple variable allows for a sophisticated operationalisation of neighbourhood histories at across time periods it does not necessarily capture all important dimensions of resources. Future work could try to include other dimensions of capital and inequality to investigate the effects of living near elite, rather than just affluent, social groups. The sequences of moving from more to less affluent neighbourhoods, and vice versa, could also be studied, as we did in an earlier paper focusing on the different temporal aspects of exposure to neighbourhood poverty. Future studies should also include the role of the school context [57], with a direct measure of it. Lack of the school context is a possible limitation of this study; however, the effect of schools can be a mediating factor in the neighbourhood effect on educational achievement in the Netherlands [58]. And finally, when longer time series become available, future studies could measure educational attainment at an older age, which may provide more accurate information on obtained diplomas and final qualifications as well as the impacts of returning to education in later adulthood.

In the introduction we observed that neighbourhood effects research is trapped in the poverty paradigm, and as a consequence focusses predominantly on the negative effects of living in poor neighbourhoods. Our study serves as an inspiration for both research and policy focused on the spatial transmission and segregation of affluence. The positive effect of growing up in an affluent neighbourhood is not a serendipitous turn of fate; urban segregation is an outcome of opportunity hoarding processes by those with the means to do so, even if people do not expect the macro level outcomes of their decisions [as in, for example, the Schelling ethnic segregation models: 59], and the overwhelming majority of households are subjected to the whims of landlords and developers controlling the housing market. By studying the effects of living in both affluent and poor environments, we have painted a fuller picture in which urban segregation is not just driven by the sociospatial transmission of deprivation, but also by most resources being concentrated in affluent neighbourhoods.

Reviewer #1: Contribution: The paper compares the effects of exposure to neighbourhood affluence and poverty on educational attainment using Netherlands data.

General comments: The paper is clear on its goal and relevance. I would recommend the authors to check the PLOS ONE template. If I am not mistaken, there is another standard format.

Specific comments (Everything that I had to read again is included here, even the obvious parts.):

[1] The introduction and the literature review are really clear on the relevance of the study, but I would recommend making them shorter. It felt too long, and too repetitive sometimes.

[2] From "This gap is striking as patterns of socio-economic segregation in cities are largely driven by the residential choices of affluent households.", which gap is striking? Are the patterns driven by residential choices or papers/data can not isolate the residential choice factor? I would also add a reference here.

[3] "better educated neighbours", not sure better is the right word here.

[4] On Page 19, what this expression "(see for instance 19)" is referring? citation?

[5] On the end of the introduction, I would recommend adding a summary of the results. The authors for instance say "we test if the exposure to the neighborhood context ...", why dont you add what you found? I do find relevant to restate the contributions on the end of the introduction.

[6] From "This paper addresses the issue of the poverty paradigm in the literature specifically paying attention to the other side of the inequality coin: spatially concentrated affluence. " - would you say that there are only two sides? is it a coin?

[7] What is your point here? : "The empirical nature of such

papers, and the strict paper structure characteristic for the middle-range social studies, usually

does not allow for extensive theoretical commentary about inequality. Nevertheless, the

concepts used in these papers are based on a variety of competing approaches to class, status

and inequality (for an early overview see 30), even if these inspirations are not immediately

visible." - It felt unnecessary to me.

[8] "won't show the same kind of assertiveness" - I would make this part more formal.

[9] What are the theoretical assumptions? "The scale of spatial research should be chosen

according to the theoretical assumptions of the study (50), and in our case we focus on

relatively small-scale, social-interactive neighbourhood effects which would happen in

neighbourhoods of about 200 households."

[10] Can you position Table 1 in the same page?

[11] What are the theoretical reasons? "We

argued that there are theoretical reasons to believe that exposure to affluence might actually be

more important as a predictor of educational attainment than exposure to poverty"

[12] From "The main outcome of this paper is that the contextual effect of neighbourhood affluence

is stronger than the effect of neighbourhood poverty. This confirms that affluence plays a

crucial role in the spatial reproduction of inequalities." -> Confirms the educational attainment or the reproduction of inequalities? Which inequalities?

[13] The images are not in a good resolution.

Reviewer #2: # Neighbourhood effects on educational attainment. What matters more: exposure to poverty or exposure to affluence?

# Summary

This paper first argues that the existing literature on neighborhood effects on individual outcomes misses a large, longstanding theoretical concept: concentration of affluence. To do this, they first present a theoretical argument grounded in sociological and political theory. They then present results from an empirical study investigating the difference between measures of concentrated affluence and concentrated poverty on individual educational attainment using a series of linear regression models. The empirical results generally support the paper’s hypothesis in the context of the Netherlands.

Overall, i enjoyed this paper and think the argument the authors are making is sound, and an important contribution to the conversation around quantiative studies of individual attainment, poverty, and spatial influence. The modeling, while simple, is a totally reasonable approach and the results are largely clear. Although the theoretical discussion could be re-structured, I really enjoyed it and applaud the authors for bringing this perspective to the literature. However, there are a number of things the authors could do to improve the paper further, particularly in the methods and analysis, that I would like to see. While most of my suggests are aimed at improving the clarity and rigor of the paper, not changing the paper entirely, I still recommend a major revision for this work.

## Strengths

### Theoretical framing

I overall enjoyed the theoretical framing of the paper. It is absolutely true that the literature over-focuses on the opportunity hoarding and individual attributes approaches. I also like the small insights into the literature nestled throughout the paper, such as the argument that using categorical income measures makes researchers more likely to focus on poverty.

### Analysis

I thought the k-nearest-neighbors approach was clever and was a good way of addressing heterogeneity in your dataset. The creation of the poverty and affluence variables was also very sensible. Results are straightforward and clear.

### Suggestions: intro, related work, background

- The theoretical background section is actually an argument, rather than a neutral background. The authors should make this more clear by, for example, adding a sentence or two in the first paragraph of the theoretical section saying “In this section, we argue that the effects of concentrated affluence

- It’s unclear to the reader how precisely the theoretical background fits in with the rest of the paper until the reader arrives at the “Current Study” section. The authors could make this more clear in the theoretical background.

- Although the authors reference many spatial inequality studies, they could cite more and be in more in-depth conversation with their approaches for the reader’s benefit.

- To address these comments, I think the theoretical and background section could be restructured to be more effective and clear. it is a combination of a critique of the existing literature and an overview of the theoretical processes the existing quantiative and spatial literature rests on. I suggest that the authors split these two goals apart into two sections. The first section could discuss explicitly recent quantitative work in the field in a more neutral manner. The second could use this grounding to critique the existing field while introducing the theoretical concepts that the paper leans on heavily.

### Suggestions: methods and analysis

- Some of the spatial variable creation could be a little unclear to some readers. My understanding is that each individual in your dataset has a grid square assigned to them as their “home” location for each time period. Within each time period, for each subject, the authors gather data on the 200 nearest households from that year, and use this household data to compute the affluence and poverty metrics. If this is the case, the authors should make this a bit clearer. As it stands, it’s a bit unclear the relationship between the grid cells and households, and if KNN was run with grid cells or historical household data.

- If spatial context is important for social interaction, etc., I’d like to see some measure of the average distance to different affluent or poor households included in the analysis. One example metric could be the mean geographic distance from grid cell to affluent households. These results may be more nuanced and reveal a bit more in terms of mechanism, which the authors are clearly interested in.

- I would also like to see much more descriptive and analytical content aimed at the measures the authors calculated. The KNN measure over years of subjects’ lives is very interesting! I want to know how this measure changes over time for different individuals. What mediates those changes? Similarly, like chetty’s study, the authors could look at *changes* in these metrics to investigate their true impact.

- Similarly, I would be interested in a model that just looks at these metrics at year 8 (2003). Are the effects and the rho similar? If so, the authors should include the framing of measuring early childhood environment to predict later outcomes.

- I think the affluent and poverty variables may be correlated, because they are calculated as percentages of the same total. I’d like to see the authors address this either through diagnostic tests or in the text of the paper.

- The authors do not present a “null” model without their spatial poverty and affluence concentration variables. I would like to see how much extra variance these variables contribute to the model. Without this measure of comparison, it’s hard to find the results very meaningful.

- I found the argument for not doing a more complicated model a little weak, and confusing at times:

- Does the explanation of “nested” individuals mean that there are many subjects who are “alone” in their cluster? If so, doesn’t this follow from the methods? Why would two individuals share the same KNN, unless they lived in the same grid cell? The authors should make this more clear.

- The authors could define what they mean by “neighborhood” here—is it the statistical / political area, or the KNN you defined above?

- I agree that a traditional multilevel model at the “neighborhood” level would likely be too complex here. But I do think the authors could include some fixed effects for general region if people are highly spatial distributed. For example, a fixed effect added for each “year x region” combination may be important. As it stands now, there are no general covariates controlling for other, unmeasured attributes of a region.

### Other Suggestions

- you only mention chetty’s study in your conclusion, but they focused heavily on the impact of affluence on educational attainment. address that!

- Although the paper is written well, there are, generally, some non-english-isms scattered throughout the paper which have made it a little hard to read as a native english speaker. The authors might consider getting a native english speaker to edit the work before publication for clarity.

- Figure 1 should be re-labeled and re-rendered—it’s very fuzzy in the copy I received and having the titles and axes in more plain english would be helpful.

- In the conclusion, the authors cite schelling differently than in the rest of the paper?

Dear Dr. Botta,

Thank you very much for the opportunity to revise and resubmit our manuscript entitled “Neighbourhood effects on educational attainment. What matters more: exposure to poverty or exposure to affluence?” (PONE-D-22-09411). And thank you for considering the paper for publication.

Based on the reviewer comments we have thoroughly revised the paper. We have restructured the paper, shortened some parts and expanded others. In this process we had to make choices, such as in the theory section as reviewer 1 asked to shorten it somewhat while reviewer 2 asked to expand and restructure some parts. We have also revised and shortened the introduction, as well as added extra explanation to the methods and analysis section and clarified some fragments pointed out by the reviewers. Overall, we feel that the reviewer comments have helped us to substantially sharpen the paper and we are grateful for their time. Please see the attached detailed replies to the reviewers’ comments for further explanation of the changes we made.

When it comes to the journal requirements regarding ethics, we work with confidential Statistics Netherlands (Centraal Bureau voor Statistiek, CBS) data. CBS is legally responsible for consent and our project has been approved by them (to get access to the data). All statistical output based on the data is checked by CBS employees to make sure it respects the privacy of the subjects. CBS is bound by the European General Data Protection Regulation (GDPR). In addition, CBS adheres to the privacy stipulations in the Statistics Netherlands Act, the European Statistics Code of Practice, and its own Code of conduct (Dutch only). The links to these documents and more explanation can be found here: https://www.cbs.nl/en-gb/about-us/organisation/privacy. Because of these privacy rules, we cannot share the data underlying our results. We have now added this clarification to the manuscript text in the Methods section (p. 14). We have also added a reference to Table 1 in the text.

We hope the revised manuscript meets your expectations.

Best wishes,

Agata Troost, Maarten van Ham and David Manley

Reviewer 1

COMMENT:

Contribution: The paper compares the effects of exposure to neighbourhood affluence and poverty on educational attainment using Netherlands data.

General comments: The paper is clear on its goal and relevance. I would recommend the authors to check the PLOS ONE template. If I am not mistaken, there is another standard format.

RESPONSE:

Thank you for reviewing our paper! We have now consulted the template and submission guidelines, and adjusted our paper by removing footnotes and changing the headings.

COMMENT:

Specific comments (Everything that I had to read again is included here, even the obvious parts.):

[1] The introduction and the literature review are really clear on the relevance of the study, but I would recommend making them shorter. It felt too long, and too repetitive sometimes.

RESPONSE:

We have edited the introduction and theory section to shorten it where possible.

COMMENT:

[2] From "This gap is striking as patterns of socio-economic segregation in cities are largely driven by the residential choices of affluent households.", which gap is striking? Are the patterns driven by residential choices or papers/data can not isolate the residential choice factor? I would also add a reference here.

RESPONSE:

We have reformulated the sentence to make it clearer: “The lack of literature on concentrated affluence is all the more striking given the influential position of affluent households: the choices of the wealthy largely shape patterns of socio-economic segregation in cities, as higher income households can use their resources to select the best residential locations in a city” (p. 3), and added a reference to Troost et al. (2021).

COMMENT:

[3] "better educated neighbours", not sure better is the right word here.

RESPONSE:

We changed “better” to “higher”.

COMMENT:

[4] On Page 19, what this expression "(see for instance 19)" is referring? citation?

RESPONSE:

The full sentence (on page 5 in our version) is “Following earlier studies (see for instance 20), we test if the exposure to the neighbourhood context (both affluence and poverty) is different for children with different parental levels of education”. “20” is indeed referring to the cited study by Sykes and Kuyper, who studied neighbourhood effects on children influenced by parental education. We reformulated the sentence to: “Following earlier studies (20)…”, which is more readable while using the Vancouver citation style.

COMMENT:

[5] On the end of the introduction, I would recommend adding a summary of the results. The authors for instance say "we test if the exposure to the neighborhood context ...", why dont you add what you found? I do find relevant to restate the contributions on the end of the introduction.

RESPONSE:

We have now briefly described our results at the end of introduction (p. 5).

COMMENT:

[6] From "This paper addresses the issue of the poverty paradigm in the literature specifically paying attention to the other side of the inequality coin: spatially concentrated affluence. " - would you say that there are only two sides? is it a coin?

RESPONSE: We have rewritten the text to remove the unintentional ambiguity in the metaphor: “This paper addresses the issue of the poverty paradigm in the literature by specifically paying attention to spatially concentrated affluence” (p. 5).

COMMENT:

[7] What is your point here? : "The empirical nature of such papers, and the strict paper structure characteristic for the middle-range social studies, usually

does not allow for extensive theoretical commentary about inequality. Nevertheless, the

concepts used in these papers are based on a variety of competing approaches to class, status

and inequality (for an early overview see 30), even if these inspirations are not immediately

visible." - It felt unnecessary to me.

RESPONSE:

Our intention was to highlight that the influence of spatially concentrated affluence has, partially, been neglected because of the research habits in the field. Because there was not always enough space or focus for the theoretical implications of approaches and theories used, it was easier for studies to remain in the “poverty paradigm” and overlook the crucial role of concentrated affluence. We hope that after the restructuring of the theory section this argument is clearer.

COMMENT:

[8] "won't show the same kind of assertiveness" - I would make this part more formal.

RESPONSE:

We have replaced it with the clarification “are unable to mobilise the same degree of social and cultural capital” (p. 10).

COMMENT:

[9] What are the theoretical assumptions? "The scale of spatial research should be chosen

according to the theoretical assumptions of the study (50), and in our case we focus on

relatively small-scale, social-interactive neighbourhood effects which would happen in

neighbourhoods of about 200 households."

RESPONSE:

We have rewritten this section to make it clearer: “The scale of spatial research should be chosen according to the theoretical assumptions of the study (51), and in our case we focus on relatively small-scale, social-interactive neighbourhood effects which would happen in neighbourhoods of about 200 households. This size should reflect a social space where people are likely to interact with each other, which, according to our assumptions, leads to acquiring skills and resources relevant for an individual’s educational attainment” (p. 16).

COMMENT:

[10] Can you position Table 1 in the same page?

RESPONSE:

The table is now moved to the next page so it doesn’t break.

COMMENT:

[11] What are the theoretical reasons? "We argued that there are theoretical reasons to believe that exposure to affluence might actually be more important as a predictor of educational attainment than exposure to poverty"

RESPONSE:

To ensure the theoretical reasons are clearer we have summarised them explicitly (see p.22): “We argued that there are theoretical reasons to believe that exposure to affluence may actually be more important as a predictor of educational attainment than exposure to poverty, because of the crucial influence of interacting with higher educated people on one’s resources, skills and educational aspirations; and, in the Dutch context, because of the lack of extreme concentrated poverty”.

COMMENT:

[12] From "The main outcome of this paper is that the contextual effect of neighbourhood affluence

is stronger than the effect of neighbourhood poverty. This confirms that affluence plays a

crucial role in the spatial reproduction of inequalities." -> Confirms the educational attainment or the reproduction of inequalities? Which inequalities?

RESPONSE:

We rewrote the beginning of that paragraph to achieve more clarity and a better flow: “Most importantly, our results highlight how spatially concentrated affluence contributes to the reproduction of socioeconomic inequalities, as the effect of neighbourhood affluence on educational attainment is stronger than that of neighbourhood poverty” (p. 23).

COMMENT:

[13] The images are not in a good resolution.

RESPONSE:

We have now attached a figure in a high quality tiff format. However, we understand that the figure at the end of the preview pdf will always be blurry unless downloaded separately.

Reviewer 2

COMMENT:

# Neighbourhood effects on educational attainment. What matters more: exposure to poverty or exposure to affluence?

# Summary

This paper first argues that the existing literature on neighborhood effects on individual outcomes misses a large, longstanding theoretical concept: concentration of affluence. To do this, they first present a theoretical argument grounded in sociological and political theory. They then present results from an empirical study investigating the difference between measures of concentrated affluence and concentrated poverty on individual educational attainment using a series of linear regression models. The empirical results generally support the paper’s hypothesis in the context of the Netherlands.

Overall, i enjoyed this paper and think the argument the authors are making is sound, and an important contribution to the conversation around quantitative studies of individual attainment, poverty, and spatial influence. The modeling, while simple, is a totally reasonable approach and the results are largely clear. Although the theoretical discussion could be re-structured, I really enjoyed it and applaud the authors for bringing this perspective to the literature. However, there are a number of things the authors could do to improve the paper further, particularly in the methods and analysis, that I would like to see. While most of my suggests are aimed at improving the clarity and rigor of the paper, not changing the paper entirely, I still recommend a major revision for this work.

## Strengths

### Theoretical framing

I overall enjoyed the theoretical framing of the paper. It is absolutely true that the literature over-focuses on the opportunity hoarding and individual attributes approaches. I also like the small insights into the literature nestled throughout the paper, such as the argument that using categorical income measures makes researchers more likely to focus on poverty.

### Analysis

I thought the k-nearest-neighbors approach was clever and was a good way of addressing heterogeneity in your dataset. The creation of the poverty and affluence variables was also very sensible. Results are straightforward and clear.

RESPONSE:

Thank you for the appreciation and the helpful summary of the paper!

COMMENT:

### Suggestions: intro, related work, background

- The theoretical background section is actually an argument, rather than a neutral background. The authors should make this more clear by, for example, adding a sentence or two in the first paragraph of the theoretical section saying “In this section, we argue that the effects of concentrated affluence

- It’s unclear to the reader how precisely the theoretical background fits in with the rest of the paper until the reader arrives at the “Current Study” section. The authors could make this more clear in the theoretical background.

- Although the authors reference many spatial inequality studies, they could cite more and be in more in-depth conversation with their approaches for the reader’s benefit.

- To address these comments, I think the theoretical and background section could be restructured to be more effective and clear. it is a combination of a critique of the existing literature and an overview of the theoretical processes the existing quantitative and spatial literature rests on. I suggest that the authors split these two goals apart into two sections. The first section could discuss explicitly recent quantitative work in the field in a more neutral manner. The second could use this grounding to critique the existing field while introducing the theoretical concepts that the paper leans on heavily.

RESPONSE:

We have now restructured the theory section and start with the overview of empirical studies, which then leads to the theoretical reasons for including affluence in the study, which in turn leads to the “Current study” section. We also added some new references, like Imbroscio and Custers & Engbersen, to add further context to this section. In addition, we used some more phrases implying we are constructing an argument.

COMMENT:

### Suggestions: methods and analysis

- Some of the spatial variable creation could be a little unclear to some readers. My understanding is that each individual in your dataset has a grid square assigned to them as their “home” location for each time period. Within each time period, for each subject, the authors gather data on the 200 nearest households from that year, and use this household data to compute the affluence and poverty metrics. If this is the case, the authors should make this a bit clearer. As it stands, it’s a bit unclear the relationship between the grid cells and households, and if KNN was run with grid cells or historical household data.

RESPONSE:

Yes! This is how we approached the neighborhoods. We agree that the text could be clearer and we have adjusted it to address this (eg. that the measures change for each year within the analysis).

COMMENT:

- If spatial context is important for social interaction, etc., I’d like to see some measure of the average distance to different affluent or poor households included in the analysis. One example metric could be the mean geographic distance from grid cell to affluent households. These results may be more nuanced and reveal a bit more in terms of mechanism, which the authors are clearly interested in.

RESPONSE:

Thank you for this comment. We had given it a lot of thought but it is not straightforward to make it operational. We can only measure difference from a cell to a cell, and a similar variable would most likely just show that a bigger geographic distance is required to reach enough affluent/poor neighbours in less densely populated areas, which is already controlled for with the “urbanisation” variable. In addition, a mean variable would just “flatten out” the average necessary distance, with it being shorter for poor households having to reach other poor (because of poor households being more prevalent in that area), etc. It could be interesting to compare similar measures for different cities or districts, but they would most likely correspond closely to the poverty/affluence ratios of bespoke neighbourhoods we already have.

COMMENT:

- I would also like to see much more descriptive and analytical content aimed at the measures the authors calculated. The KNN measure over years of subjects’ lives is very interesting! I want to know how this measure changes over time for different individuals. What mediates those changes? Similarly, like chetty’s study, the authors could look at *changes* in these metrics to investigate their true impact.

RESPONSE:

We have studied the influence of subjects’ neighbourhood trajectories / individual neighbourhood histories sequences in our previous study, and considered adding the data on them to this paper as an extra context (percentages of individuals with constant low poverty neighbourhood histories, constant low affluence, constant medium poverty etc…). However, because of word count limitations and no clear theoretical relevance of these sequences to the rest of the paper, we have decided to omit this extra information in the current paper. Our other paper discusses in depth the differences between different longitudinal measurements of the bespoke neighbourhoods. The statistical models we are using in this paper were chosen as the clearest and most relevant ones for the affluence/poverty comparison.

COMMENT:

- Similarly, I would be interested in a model that just looks at these metrics at year 8 (2003). Are the effects and the rho similar? If so, the authors should include the framing of measuring early childhood environment to predict later outcomes.

RESPONSE: We have looked at the models and while the effects of one year compared to multiple years are similar, we believe that including longer measurement periods provides a better reflection of the underlying processes we are exploring and the accumulation of live deposits. We already look at both early childhood and adolescence, in addition to the total childhood years, predicting our main outcome of interest, educational attainment.

COMMENT:

- I think the affluent and poverty variables may be correlated, because they are calculated as percentages of the same total. I’d like to see the authors address this either through diagnostic tests or in the text of the paper.

RESPONSE:

The correlation between the variables is -.45, therefore the correlation is not problematic for the models. We have now added this information to the text on page 16 (“The variables are not correlated (-.45)”).

COMMENT:

- The authors do not present a “null” model without their spatial poverty and affluence concentration variables. I would like to see how much extra variance these variables contribute to the model. Without this measure of comparison, it’s hard to find the results very meaningful.

RESPONSE:

The spatial variables contribute around 3% difference in R-squared (from around 15% with no spatial variables, through 16% with only the urbanisation control, to 18% with all spatial variables). While it doesn’t seem to be a big difference, it is the type of difference that can be expected from similar variables in sociological models. Additionally, including the spatial variables diminishes the effects of other variables in the model, such as family income, which means the spatial variables contribute to the underlying causal structures.

COMMENT:

- I found the argument for not doing a more complicated model a little weak, and confusing at times:

- Does the explanation of “nested” individuals mean that there are many subjects who are “alone” in their cluster? If so, doesn’t this follow from the methods? Why would two individuals share the same KNN, unless they lived in the same grid cell? The authors should make this more clear.

RESPONSE:

We have now rewritten the section and added more explanation to make it clearer (on p. 18): “Given the nested structure of our data, the use of multilevel modelling appears logical. However, there are two reasons why we have not used this type of models. Firstly, individuals are nested in neighbourhoods which can change every year. Therefore, the complex hierarchical structure inhibits model convergence. This is further exacerbated by the second reason, whereby there is no strict hierarchy because of the multiple membership of individuals in the bespoke neighbourhoods (the neighbourhoods are overlapping with each other). Furthermore, because of bespoke neighbourhoods which are constructed for each individual every year, and only including people born in 1995 in the sample, a large number of individuals are “nested” alone or with just one other person in their neighbourhood (73,367; 49%), which is another obstacle to estimating a hierarchical fixed effects structure.”

COMMENT:

- The authors could define what they mean by “neighborhood” here—is it the statistical / political area, or the KNN you defined above?

RESPONSE:

Unfortunately we do not know to which line this comment refers to, specifically, but in general we refer to the 200-nearest neighbouring households, bespoke neighbourhoods we created. In revising our paper we have paid attention to this issue to ensure that the meaning of neighborhood is clear.

COMMENT:

- I agree that a traditional multilevel model at the “neighborhood” level would likely be too complex here. But I do think the authors could include some fixed effects for general region if people are highly spatial distributed. For example, a fixed effect added for each “year x region” combination may be important. As it stands now, there are no general covariates controlling for other, unmeasured attributes of a region.

RESPONSE:

We have an urbanisation control variable, but none about the region. However, the Netherlands’ regions do not significantly differ when it comes to economic performance, education quality, and other relevant variables we can think of. There are differences between big cities and more rural regions, but these are captured by the urbanisation control variable. The quality of eg. high schools is the same in Amsterdam, Nijmegen or Maastricht. Regions which are “less economically developed” are also less urbanised, eg. The province of Groningen consists mostly of farming fields, while provinces in the Randstad, such as Utrecht and South Holland, are highly urbanised. This has to do with the Netherlands being a very small, densely populated country in general. Additionally, given the number of years in the analysis, creating so many interaction variables with region per year would not be workable.

COMMENT:

### Other Suggestions

- you only mention chetty’s study in your conclusion, but they focused heavily on the impact of affluence on educational attainment. address that!

RESPONSE:

We have now added a reference to Chetty earlier in the paper. However, the “better neighbourhoods” in Chetty et al. are neighbourhoods with low(er) poverty rather than high affluence, so we could not identify in it an operationalisation of affluence that would be of high relevance to our paper.

COMMENT:

- Although the paper is written well, there are, generally, some non-english-isms scattered throughout the paper which have made it a little hard to read as a native english speaker. The authors might consider getting a native english speaker to edit the work before publication for clarity.

RESPONSE:

Thank you, a native English speaker has checked the paper.

COMMENT:

- Figure 1 should be re-labeled and re-rendered—it’s very fuzzy in the copy I received and having the titles and axes in more plain english would be helpful.

RESPONSE:

We have now adjusted the labels and made sure to attach a figure in a high quality tiff format to the submission. However, the figure at the end of the preview pdf might still be blurry because of compression.

COMMENT:

- In the conclusion, the authors cite schelling differently than in the rest of the paper

RESPONSE:

Thank you! We have now corrected the reference.

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: The paper shows that the neighborhood affluence has a stronger effect on educational attainment than neighborhood poverty in the Netherlands.

Even though the paper was improved, there are still inadequate sentences such as "These results highlight the need for more studies on the effects of concentrated affluence, and they can inspire policies focused on the segregation of richer households." - What do you mean "can inspire policies focused on the segregation"? Is segregation something positive in this context? Why?

Several informal expressions such as "Perhaps","In doing so", "This is what we had in mind with the current paper", "according to our assumptions

Excessive use of "" in the paper

Multiple places without references using very strong statements such as "there are theoretical reasons to believe that exposure to affluence may actually be more important as a predictor of educational attainment than exposure to poverty","As already discussed, poverty is often associated with crime and isolation of minority groups."

The limitations of the work are not in line with the following statement: "we have painted a fuller picture in which the spatial transmission of poverty is not an isolated problem, but one reinforced by most resources being concentrated somewhere else."

I am not sure whether it can be also concluded that "Our results support our initial idea that it is often the lack of resources in poor and middle income neighborhoods that is the problem, not the theorized negative effects of poverty itself."

As the subject of the paper is inequality, I would recommend the authors to tune down the statements (especially the ones that imply "cause and consequence") and use more formal and well accepted jargon.

Reviewer #2: - Thanks to the authors for making these significant adjustments to the paper. I think the structure and presentation are clearer, and many of comments have been addressed. Kudos!

In general I recommend it for publication, but I would strongly encourage the authors to include these final changes in the submitted version for the reader. I think adding these will help you convince more quantitatively minded readers of your argument.

- I could be missing it, but if you do study neighborhood trajectories from the KNN approach in a prior study like you mention in your rebuttal, please reference it when discussing the KNN method or results so that a reader can find that work fairly easily. It is a logical train of thought to want to learn more about the construct you’ve made.

- I am still a little concerned about the affluent and poverty variables. While not quite a composition, it is close to one as the two variables before being averaged across years are constrained. The correlation is also strongly *negative*, not “not correlated” at -.45. I would just mention this and add an argument why you feel there is no need to transform the variables (e.g. see https://link.springer.com/chapter/10.1007/978-3-642-36809-7_5), or include the VIF for your models to convince the reader that there is not a multicollinearity problem.

- I would also include the reasoning you gave me for not including the 'average distance' to different affluent or poor households, mainly because I do not find your answer totally satisfying. You argue that 200 households is a good proxy for social interaction, but the likelihood of interaction with the nearest 200 households for a rural community vs a dense urban one are wildly different in my view. I don't think that controlling for urban density ("urbanity") is enough to capture this. I'd like to see either some text addressing this specifically on e.g. page 16, or some statistics showing me that the urbanization variable highly correlates with a household's avg. distance to poor and affluent households. If it doesn't, I think it would show that there is variation your analysis isn't capturing. Even if that's the case, you can show that and then mention why you don't operationalize it. As it stands it's still a question I have reading the paper.

- Regarding the “null” model, thanks to the authors for their explanation. However, I would like the explanation you gave me in the review to be present in the text.

Author response to Decision Letter 1


31 Dec 2022

(see also the doc file submitted earlier)

Dear Dr. Botta,

Thank you very much for the opportunity to revise our manuscript entitled “Neighbourhood effects on educational attainment. What matters more: exposure to poverty or exposure to affluence?” (PONE-D-22-09411R1). And thank you for considering the paper for publication.

We have addressed the reviewers’ comments individually, in the text below. In general, according to the comments of Reviewer 1 we made the text more specific and formal. Following the comments of Reviewer 2, we have added a control variable and we have clarified a number of methodological assumptions and conditions in the text. We feel that the reviewer comments have helped us to further improve the paper and we are grateful for their time.

In one of the comments Reviewer 2 asks us to add a specific reference to our earlier work in the text. In order for the reviewers to still be able to anonymously assess the manuscript, we have replaced this reference in text with “[REDACTED]”. The reference should be:

[Redacted for anonymity - please see the comments to the journal office / the doc file]

We hope the revised manuscript meets your expectations.

Best wishes,

[Redacted for anonymity - please see the comments to the journal office / the doc file]

REVIEWER 1

COMMENT:

Reviewer #1: The paper shows that the neighborhood affluence has a stronger effect on educational attainment than neighborhood poverty in the Netherlands.

Even though the paper was improved, there are still inadequate sentences such as "These results highlight the need for more studies on the effects of concentrated affluence, and they can inspire policies focused on the segregation of richer households." - What do you mean "can inspire policies focused on the segregation"? Is segregation something positive in this context? Why?

RESPONSE:

We have now rephrased that sentence as: “These results highlight the need for more studies on the effects of concentrated affluence, and they can inspire anti-segregation policies focused on the concentration of rich households” (p. 2).

COMMENT:

Several informal expressions such as "Perhaps","In doing so", "This is what we had in mind with the current paper", "according to our assumptions

Excessive use of "" in the paper

RESPONSE:

We have made the language more formal and reduced the usage of quotation marks where possible.

COMMENT:

Multiple places without references using very strong statements such as "there are theoretical reasons to believe that exposure to affluence may actually be more important as a predictor of educational attainment than exposure to poverty","As already discussed, poverty is often associated with crime and isolation of minority groups."

RESPONSE:

For the second cited statement, we have now added references to support it (p. 8):

DeLuca S, Duncan GJ, Keels M, Mendenhall R. The notable and the null: Using mixed methods to understand the diverse impacts of residential mobility programs. In: Neighbourhood effects research: New perspectives. Springer; 2012. p. 195–223.

Sharkey P. Uneasy peace: The great crime decline, the renewal of city life, and the next war on violence. WW Norton & Company; 2018.

The first statement, however, is in the beginning of the conclusion section and summarises our theoretical background section argument, based on multiple studies. We therefore do not think adding one or two references would make sense here, or even referring to all the studies we referenced in theoretical background to make our argument, as the sentence refers to the argument we formulated ourselves. Its function as a summary is clearer while looking at the full sentence (p. 23): “We argued that there are theoretical reasons to believe that exposure to affluence may actually be more important as a predictor of educational attainment than exposure to poverty, because of the crucial influence of interacting with higher educated people on one’s resources, skills and educational aspirations; and, in the Dutch context, because of the lack of extreme concentrated poverty.”

COMMENT:

The limitations of the work are not in line with the following statement: "we have painted a fuller picture in which the spatial transmission of poverty is not an isolated problem, but one reinforced by most resources being concentrated somewhere else."

RESPONSE:

We have reformulated the sentence as “By studying the effects of living in both affluent and poor environments, we have painted a fuller picture in which urban segregation is not just driven by the sociospatial transmission of deprivation, but also by most resources being concentrated in affluent neighbourhoods” (p. 25).

COMMENT:

I am not sure whether it can be also concluded that "Our results support our initial idea that it is often the lack of resources in poor and middle income neighborhoods that is the problem, not the theorized negative effects of poverty itself."

RESPONSE:

We have now added more details to make the sentence clearer: “Our results, specifically the effect of spatially concentrated affluence being stronger than that of poverty, support our initial idea that it is often the lack of resources – the cultural and economic capital of richer neighbours - in poor and middle income neighbourhoods that is the problem, not the theorised negative effects of poverty itself” (p. 24).

COMMENT:

As the subject of the paper is inequality, I would recommend the authors to tune down the statements (especially the ones that imply "cause and consequence") and use more formal and well accepted jargon.

RESPONSE:

We have edited the statements to be more nuanced (as also detailed in the previous comments) and made the language of the paper more formal.

REVIEWER 2

COMMENT:

Reviewer #2: - Thanks to the authors for making these significant adjustments to the paper. I think the structure and presentation are clearer, and many of comments have been addressed. Kudos!

In general I recommend it for publication, but I would strongly encourage the authors to include these final changes in the submitted version for the reader. I think adding these will help you convince more quantitatively minded readers of your argument.

RESPONSE:

Thank you for the kind words and useful comments!

COMMENT:

- I could be missing it, but if you do study neighborhood trajectories from the KNN approach in a prior study like you mention in your rebuttal, please reference it when discussing the KNN method or results so that a reader can find that work fairly easily. It is a logical train of thought to want to learn more about the construct you’ve made.

RESPONSE:

As the study we mentioned has been published in the meantime, we have added references to it (p. 16, p. 25). We marked the reference in the manuscript as [REDACTED] and sent the actual reference to the editor, as sharing it with the reviewers in possible future rounds of reviews would mean that the review is not double blind anymore.

COMMENT:

- I am still a little concerned about the affluent and poverty variables. While not quite a composition, it is close to one as the two variables before being averaged across years are constrained. The correlation is also strongly *negative*, not “not correlated” at -.45. I would just mention this and add an argument why you feel there is no need to transform the variables (e.g. see https://link.springer.com/chapter/10.1007/978-3-642-36809-7_5), or include the VIF for your models to convince the reader that there is not a multicollinearity problem.

RESPONSE:

We have now added this explanation, on p. 19: “VIF values were unproblematic, therefore there are no issues with multicollinearity in the models (see Appendix for exact VIF values)”, and also changed “not correlated” to “weakly correlated”.

COMMENT:

- I would also include the reasoning you gave me for not including the 'average distance' to different affluent or poor households, mainly because I do not find your answer totally satisfying. You argue that 200 households is a good proxy for social interaction, but the likelihood of interaction with the nearest 200 households for a rural community vs a dense urban one are wildly different in my view. I don't think that controlling for urban density ("urbanity") is enough to capture this. I'd like to see either some text addressing this specifically on e.g. page 16, or some statistics showing me that the urbanization variable highly correlates with a household's avg. distance to poor and affluent households. If it doesn't, I think it would show that there is variation your analysis isn't capturing. Even if that's the case, you can show that and then mention why you don't operationalize it. As it stands it's still a question I have reading the paper.

RESPONSE:

Thank you for this comment. We have discussed the issue of the average distance again. Because the correlation between the average distance (measured by Equipop in kilometres necessary to reach the 200 nearest households) and urbanicity (as we decided to rename the variable more accurately) isn’t strong (-0.37 for both high and low income), we decided to add the average distance as a control variable in our models. We believe it helps to control for density of social interaction at a lower level than the urbanicity variable. Adding the variable did not change the significance of any of the other variables except for being of a Western migrant background, but it did influence the strength of the observed effects, making the influence of spatially concentrated affluence stronger than before, and that of poverty a bit weaker. The N of the dataset for analyses changed to 140,338 because of that, but as this indicated that previously some of the bespoke neighbourhood-based variables included squares with missing information for some years, we believe this is an improvement of the study.

COMMENT:

- Regarding the “null” model, thanks to the authors for their explanation. However, I would like the explanation you gave me in the review to be present in the text.

RESPONSE:

We have now added the explanation to the text on page 19: “The spatial variables contribute around 3% difference in R-squared – from around 15% in models with no spatial variables (for detailed coefficients, see Appendix), through 16% with only the urbanicity control, to 18% with all spatial variables – which is the type of difference that can be expected from similar variables in sociological models. Additionally, including the spatial variables diminishes the effects of other variables in the model, such as family income, which means the spatial variables contribute to the underlying causal structures.”
