Abstract
Rising student debt has sparked concerns about its impact on the transition to adulthood. In this paper, we examine the claim that student debt is leading to a rise in “boomeranging”, or returning home, using data from the National Longitudinal Survey of Youth 1997 Cohort and discrete time event history models. We have four findings. First, student loan debt is not associated with boomeranging in the complete sample. However, we find that the association differs by race, such that the link between student debt and returning home is stronger for black than white youth. Third, degree completion is a strong predictor of returning home, whereby those who fail to attain a degree have an increased risk of boomeranging. Fourth, young adult role transitions and socioeconomic well-being are associated with boomeranging. Findings suggest that rising debt has created new risks, and may reproduce social inequalities in the transition to adulthood.
INTRODUCTION
Leaving the parental home is a key marker in the transition to adulthood (Furstenberg 2010, Goldscheider and Goldscheider 1999), and a signal for economic independence (Sironi and Furstenberg 2012). But recently scholars have become concerned with reversibility of the transition to adulthood (Shanahan 2000), and the phenomenon of “boomeranging”—where young adults return home after attaining residential independence (Goldscheider and Goldscheider 1999). The most recent cohort of young adults have been dubbed “the boomerang generation” (Parker 2012), and are returning home at a faster rate than previous cohorts. Although research has begun to interrogate the causes and consequences of boomeranging (Goldscheider and Goldscheider 1999, Sassler, Ciambrone and Benway 2008, South and Lei 2015, Stone, Berrington and Falkingham 2014), relatively little is known about this shift in the transition to adulthood, particularly among college-going youth.
Many have argued that the rapid increase in student debt explains the recent rise in boomeranging among young people (Bleemer et al. 2014, Davidson 2014). While these arguments raise important questions, there is little evidence regarding the link between debt and boomeranging. Moreover, despite a growing and diverse college-going population, and a large proportion of college goers that leave college without a degree (Buchmann and Diprete 2006), no research to date has examined how postsecondary educational (PSE) experiences are linked with boomeranging.
In this study, we ask whether student debt is associated with boomeranging among a cohort of college-going young adults. Specifically, we test three distinct claims: First, that student debt hastens boomeranging, because it creates social and economic difficulties for youth. Second, that there is heterogeneity in the association between debt and boomeranging by race. Third, that failing to complete college creates difficulties in young adulthood and leads youth to boomerang, not student debt.
LITERATURE REVIEW
The transition to adulthood—the period of life when young people exit adolescent social roles and enter adult social roles such as full-time employment, marriage, and residential independence—has undergone dramatic changes over the past several decades (see Shanahan 2000 for review). Chief among these changes is that young adults delay entry into traditional adult roles, in part because they spend more time in PSE institutions (Furstenberg 2010). This is reflected in the dramatic expansion of higher education throughout the 20th and 21st centuries, as changes in the structure of the labor market have made it necessary for youth to pursue a college degree to attain middle class jobs (Danziger and Ratner 2010). From 1967 to 2012, the percent of young people age 18–24 enrolled in college increased nearly 61%, from 25.5% to 41% (National Center for Education Statistics 2013a). Simultaneously, the cost of higher education increased, and student aid stagnated, leading students and their families to take on historic levels of debt to fund college-going. Student debt has doubled in the past decade, topping 1 trillion dollars in the aggregate, with the average college graduate debtor owing $30,000 (Federal Reserve Bank of New York 2013, Project on Student Debt 2011).
Rising debt levels have fueled scholarly and public concern about the potential impact of student debt on the well-being of young adults, though findings have been mixed (Addo 2014, Dwyer, McCloud and Hodson 2011, Houle and Berger 2015, Nau, Dwyer and Hodson 2015). Most recently, scholars have expressed concern that rising student debt is contributing to the “boomerang generation” of young adults returning home. Estimates of boomeranging vary, with recent studies reporting between 20% and 50% of young adults boomerang (Parker 2012, Sandberg-Thoma, Snyder and Jang 2015, South and Lei 2015, Stone, Berrington and Falkingham 2014). In earlier work, Goldscheider and colleagues (1994, 1999, 1999) report that the percent of young adults who boomerang at least doubled over the course of the 20th century. And, recent reports suggest that the rise in boomeranging is particularly pronounced among college-going young adults (Stone, Berrington and Falkingham 2014) who have diminished labor market prospects in the wake of the Great Recession and are struggling with student debt (Dettling and Hsu 2015, Fry 2015). Below, we review existing research and theories centered around three distinct claims regarding the link between student debt and boomeranging: (1) that student debt hastens boomeranging; (2) that this association is stronger for black than white youth; (3) that college completion, not debt, is the key predictor of boomeranging. These claims are summarized graphically in Figures 1a–1c.

Student Debt and Boomeranging: Evidence and Mechanisms
That student debt is leading a generation of young people back home is a compelling, plausible hypothesis: when young people leave home, debt payments may become burdensome—particularly given that it cannot be discharged in bankruptcy—and debt may lead to other pernicious outcomes that hasten a return home. Below, we consider four (non-independent) pathways through which debt may influence boomeranging: economic strain, college completion, delayed transition to adulthood, and youth well-being.
First, student debt may lead young people to boomerang because it creates economic strain as they struggle to keep up with payments. Life course scholars find that economic strain is an important proximate determinant of boomeranging among young adults (Goldscheider and Goldscheider 1999), which provides suggestive evidence that student debt may increase the risk of boomeranging to the extent that debt is tied to economic strain. For example, becoming unemployed and declines in wages increase the risk that young adults boomerang (South and Lei 2015, Stone, Berrington and Falkingham 2014). Just as wages and unemployment are predictive of boomeranging, high debt loads among college-going youth may be an important contemporary indicator of economic distress, whereby those struggling with debt may have a heightened risk of boomeranging.
Relatedly, student debt may lead to boomeranging if it interferes with degree attainment. Dwyer and colleagues (2012) show that high debt burdens are associated with an increased risk of dropping out of college. Although there is no evidence on the link between degree attainment and boomeranging, young people who leave college without a degree face higher unemployment rates and lower wages than college graduates (Cellini and Chaudhary 2014, Lang and Weinstein 2013), and thus may be at a higher risk for boomeranging.
Third, student debt may increase the risk of boomeranging because it leads to delays in other adult role transitions. For example, young adults with high student debt are less likely to transition from cohabitation to marriage (Addo 2014), and high debt is also associated with delayed fertility (Nau, Dwyer and Hodson 2015). Boomeranging research shows that delays in such transitions—as well as union dissolution, leaving college, and nonmarital pregnancy—are associated with an increased risk of returning home (Sandberg-Thoma, Snyder and Jang 2015, South and Lei 2015, Stone, Berrington and Falkingham 2014).
Finally, the association between debt and boomeranging may operate through youth well-being. Walsemann and colleagues (2015) show that student debt is linked to poor young adult mental health, and young people with emotional problems are more likely to boomeranging (Sandberg-Thoma, Snyder and Jang 2015). To the extent that student debt impacts emotional well-being, this may be a mechanism through which student debt impacts boomeranging.
In sum, the above arguments suggest that we would expect to observe a bivariate (positive) association between student debt and boomeranging, and that this association should be partially or fully mediated by young adult economic circumstances, college completion, transition to adulthood status, and youth well-being.
Few studies examine the link between student debt and boomeranging, with the exception of two reports produced by the Federal Reserve Board. Dettling and Hsu (2015) use credit-report data, and show that student debt is positively associated with boomeranging, and that this association is larger for subprime borrowers. While this study provides important evidence, it is limited in the following ways: first, the credit report data omits non-debtors (those without credit reports). Second, the credit report data lacks information on individual-level socioeconomic and PSE characteristics, which are crucial to fully understand the association between debt and outcomes (Houle 2014). Third, residence with parents is largely inferred using mailing addresses and differences in ages between individuals living in a household, rather than directly identifying parent-children pairs or respondent report of residence. Another study (Bleemer et al. 2014), using aggregated data from credit reports, found that state-level debt loads are associated with state-level rates of co-residing with parents. These studies, while illustrative, do not directly measure boomeranging at the individual-level, do not include non-debtors with no credit history, and do not consider individual-level mechanisms and confounders of the association between debt and boomeranging. Our study, which utilizes longitudinal individual-level survey data of a nationally representative sample, allows us unique leverage regarding this question.
Student Debt and Boomeranging: Variation by Race
While the above argument implies that student debt may be uniformly negative for young adults, other scholars have argued that debt may be more burdensome for some groups than others, and have differential consequences across groups, particularly by race. Research in this vein shows student debt may be more burdensome and difficult to repay for black young adults than for white young adults for two key reasons. First, black young adults have significantly higher debt burdens than whites (Cunningham and Santiago 2008, Houle 2014, Jackson and Reynolds 2013), such that blacks are both more likely to borrow, owe $5,000 to $10,000 more than white debtors, and are more likely to default on loans (Houle 2014, Huelsman 2015, Jackson and Reynolds 2013). Second, black young adults experience more hardship and discrimination that makes debt more burdensome to repay and leads debt to have more pernicious consequences.
Discrimination in credit, college, and labor markets are key mechanisms by which debt becomes be more burdensome (and difficult to repay) for blacks than whites. Although student debt is often used by black students to bridge the gap between family resources and the rising costs of college, black youth are more likely to have private loans, which carry high and variable interest rates, have high fees for deferment and forbearance, and offer less protection for borrowers than federal loans (Goldrick-Rab, Kelchen and Houle 2014, Project on Student Debt 2014). In this way, the student loan market is not unlike the mortgage market, where blacks often lack access to fair credit, and instead are more likely to have access to predatory, high interest loans that are difficult to repay (Williams, Nesiba and McConnell 2005). Black youth also have more difficulty repaying loans due to discrimination and hardship in the college market. For example, black young adults are often funneled toward or have access limited to predatory for-profit institutions and underfunded schools, which offer fewer labor market benefits and have high drop-out rates (Ruch 2001). Finally, even among college graduates, black youth experience discrimination in the labor market, and are less likely to obtain job offers than their white counterparts, and often receive offers for lower paying positions with fewer options for career advancements than white college graduates (Gaddis 2015). More broadly, black-white disparities in earnings, employment, and wealth are observable in young adulthood (Cancio, Evans and Maume 1996, Zhang 2008), and due to their precarious economic position black youth may have more difficulty repaying student debt after leaving college.
Supporting these notions, recent evidence suggests that student debt has more negative consequences for black youth than white youth. For example, 69% of blacks who dropout cite student debt as a primary reason for not completing their degree, compared to 43% of white students (Johnson, Van Ostern and White 2012). After leaving college, blacks also report being significantly more concerned about being able to afford student loan payments than whites (Ratcliffe and McKernan 2013), and have more difficulty paying off equivalent amounts of debt than white young adults (Addo, Houle and Simon 2016), which may be a result of high interest rates, and because of lower labor market returns to a college degree. That is, black young adults not only face higher debt burdens than their white counterparts, and thus are exposed to greater risks in their college experience, but they are also experience fewer rewards to a college degree (Addo, Houle and Simon 2016). This suggests that to the extent that student debt creates economic strain and drives young people back to the parental home, the impact of student debt on boomeranging may be stronger for blacks than it is for whites. Although one could reasonably hypothesize that the consequences of debt may vary by other characteristics (such as gender or class), we focus on race because: 1) black-white differences in debt are substantially larger than gender and socioeconomic background in debt (Addo, Houle and Simon 2016, Houle 2014) and 2) the burden of student loan debt is uniquely racialized, for the reasons stated abovei.
A Completion Crisis Not a Debt Crisis: Implications for Boomeranging
A third claim in the literature is that college completion and subsequent labor market attachment better explain the rise in boomeranging than does student debt. While many argue that student debt has disastrous consequences, other scholars argue that the student debt crisis is not a debt crisis, but a degree completion and for-profit crisis (Dynarski and Kreisman 2013, Dynarski 2015, Looney and Yannelis 2015). That is, those who are struggling with loan repayment are not struggling because they carry high loan balances, but because they leave college without a degree, and attend institutions that have low completion rates and fewer labor market benefits, such as for-profits and two-year institutions (Akers and Chingos 2016). For example, Houle and Berger (2015) challenge recent claims that student debt is dragging down the housing market, and find only a trivial association between student debt and home ownership outcomes. Instead, they find that degree completion is a stronger predictor of home ownership. Indeed, recent estimates suggest that student debt may not be as burdensome as is suggested in popular discourse. For example, the median student debtor pays only 3–4% of their monthly income on student loan payments, a figure which has remained relatively constant since the early 1990s (Akers and Chingos 2016). As such, degree completion may be a stronger predictor of boomeranging than student debt, ceterus perebus. Unlike the above argument, which suggests that college completion and PSE characteristics may mediate the link between student debt and boomeranging, this argument suggests that PSE characteristics and completion are independent predictors of boomeranging, and implies that debt is not a culprit in the rise of boomeranging.
This argument dovetails with sociological research on higher education. While access to PSE in the U.S. has increased over the course of the 20th century, these institutions have also become more stratified and diverse in ways that exacerbate inequality (Dwyer, McCloud and Hodson 2012). Much of the growth in higher education has been in two-year and lower-tier institutions (such as for-profits) that primarily cater to disadvantaged students (Roksa et al. 2007). While attending such institutions may serve as a stepping stone for upward mobility, graduation rates at these institutions are significantly lower than traditional 4-year non-profit institutions, whereby approximately 31% of students at two-year institutions (National Center for Education Statistics 2013c), and 23% of students at four-year for-profit institutions graduate within 150% of normal time (National Center for Education Statistics 2013b), and those who do not complete their degree do not experience the labor market benefits associated with a college degree (Hout 2012). Moreover, graduates of these institutions tend to have lower status and lower wage jobs than 4-year non-profit college graduates, suggesting that degrees from these types of institutions do not confer the same benefits as four year degrees from public and private non-profit institutions (Cellini and Chaudhary 2014, Lang and Weinstein 2013). Given that non-completion and low status PSE institutions are linked with fewer social and economic rewards, these factors may be important predictors of boomeranging.
Recent research provides suggestive, but not conclusive, evidence that college degree completion is associated with returning home, and no research has explored how PSE characteristics are linked with boomeranging. South and Lei (2015) find some support for the above argument and show that leaving college is associated with an increased risk of returning home. Similarly, Stone et al. (2014) find that young adults transitioning out of school and into the labor market in England have a higher risk of returning home than young adults who are stably employed. However, these analyses conflate leaving school with degree completion, and thus it is not clear whether there are differences in risk of returning home by completion status. Moreover, both studies include young adults with less than or equal to a high school degree who never attended college in their reference group, thus raising further questions about whether non-completers are more likely to return home than degree completers. Thus, the link between student debt, college completion, PSE characteristics, and returning to the parental home is unclear.
In sum, in this study we test three claims regarding the impact of student debt on boomeranging. First, that student loan debt is associated with an increased risk of boomeranging; Second, that this effect is stronger for black youth, for whom debt is more burdensome; and Third, that college completion, rather than debt, is most germane for boomeranging. In doing so, we contribute to two distinct literatures on the consequences of student debt and young adulthood, as well as research on the changing transition to adulthood, by examining the link between student debt, college completion, and the changing landscape of the transition to adulthood.
DATA AND METHODS
Data
Data for this study are drawn from the National Longitudinal Study of Youth 1997 Cohort (NLSY-97). The NLSY-97 is a nationally representative sample of 8,984 respondents born between 1980 and 1984. Survey respondents have been interviewed yearly since the original round of data collection in 1997 except for a two-year gap between the 2011 and 2013 waves. The NLSY-97 data are particularly well-suited for our analyses in that the panel follows a recent cohort of youth that hold historically high levels of student loan and consumer debt during their transition into adulthood. We restrict the original sample of 8,984 respondents in several ways. First, we limit our analysis to respondents who ever attended college, and thus were at risk to accumulate student debt (N=5,615). Second, for the main analysis, we keep only those college-goers who achieve residential independence (N=5,063), eliminating those respondents who fail to launchii. Third, we drop 32 respondents who report living independently or returning to the parental household before the start of the data series. Fourth, we dropped 6 college-goers who reported returning to the parental household before they reported living independently (N=5,025), which we then restructured into a person-wave format (Person-Waves=90,468). We then drop all observations following a return to the parental household (N=5,025; Person waves=31,731). To account for missing data, we use multiple imputation using the ICE command in Stata 14.0 (Royston 2005). Multiple imputation is a more efficient and less biased strategy for missing data than listwise deletion (Lee and Carin 2010). The procedure iteratively replaces missing values on all variables with predictions based on random draws from the posterior distributions of parameters observed in the sample, creating multiple complete datasets (Allison 2001). We average results across 15 imputation samples and account for random variation across samples to calculate standard errors (Royston 2005). The multiply-imputed results presented here are similar to results using listwise deletion.
Measures
Boomeranging
Prior research has relied on annual household rosters to measure exits from and returns to the parental household (see Sandberg Thoma et al 2015; South and Lei 2015). Respondents are considered residentially independent when a parent no longer appears on the household roster, and boomeranging is coded as 1 if a respondent who becomes residentially independent later reports a parent on the household roster. We argue that such a measure is not ideal among a college-going population. First, the NLSY asks only about one’s current household, which may bias estimates for populations whose current or usual residence is ambiguous, such as college-going youth (Martin 1999, Martin 2007). Relatedly, many youth report their parents on the household roster when they are enrolled in college and living on campus (Thompson 2014), which creates measurement error. Third, shorter spells of residential independence (especially those lasting less than one year) are not captured by the annual household roster. For all of these reasons, the Bureau of Labor Statistics has not relied on household roster measures in the NLSY when examining boomeranging (Dey and Pierret 2014).
A measure based on respondents’ own reports of their residential independence is preferable. Starting in 2003, NLSY-97 respondents were asked retrospectiveiii questions about the month and year in which they first exited and the month and year they returned to the parental home (if applicable). After 2003, respondents are asked about these transitions at every subsequent wave. As part of this question, respondents are given a direct definition of living on their own, and asked if they have ever established their own household for at least three months.iv Those who lived independently are then asked if they ever returned to the parental household for a period of at least three monthsv and the month and year when that occurred. Residentially independent respondents are coded as 1 in the year they report moving back home. This measure is less biased than the household roster measure for several reasons. First, respondents are asked specifically about residential transitions, rather than inferring the transitions from the household roster of one’s implied current residence. Second, the measure avoids bias via shorter-term living situations (such as dorms, or residential spells in college) because respondents are first prompted with a definition of permanent housing: “Sometimes people live in places temporarily while attending school or working a job or for some other reason, but they consider their permanent residence to be elsewhere. Do you consider the place you are currently living to be your permanent house?” Because they are prompted with a clear definition of permanent housing, respondents are less likely to consider short term or temporary moves when discussing their boomeranging history (Martin, Fay and Krejsa 2014). Third, because respondents report the month and year of each transition, we can capture exits and returns that last less than one year. This is an important group, as nearly 11% of residentially independent respondents who return home do so in the first year. By asking youth specifically about their residential independence that is not temporary, we get a direct, rather than in indirect measure that is likely less biased than the household roster measure (Dey and Pierret 2014). However, one potential shortcoming of our measure of boomeranging is that respondents are asked if they “move in with their parents or someone else’s household.” While that someone else could conceivably be a romantic partner, we include controls for cohabitation and marital status. To the extent that this boomeranging measure captures moves with other family members, this likely reflects family structure variation in the U.S. Given the variety of family structures in the United States, we would contend that moving in with other relatives (rather than parents) is conceptually similar to boomeranging. However, as a robustness check, we also construct a boomeranging measure based on the household roster, and briefly report these findings below.
Student debt
Our focal independent variable is student debt. Respondents were asked questions about types and amounts of debt holdings and assets, including student debt, at approximately age 20, 25, and 30 as part of the NLSY debts and assets modules (YAST). We adjusted debt for inflation and standardized it to reflect 2010 dollars using the Consumer Price Index Research Series (CPI-U-RS) (Bureau of Labor Statistics 2010). While accuracy of self-reported debt data is a concern, evidence shows that borrower self-reports and credit reports are extremely similar for nearly all forms of debt, including student debt (Brown et al. 2011). We use linear interpolation to impute debt between YAST modulesvi, and include the natural log of this measure in our empirical modelsvii.
Covariates
We include an array of time-invariant and time-varying covariates in our models that may confound, suppress, or mediate the link between student debt and boomeranging. Because sociodemographic background is associated with debt accrual (Houle 2014) and boomeranging (South and Lei 2015), time invariant controls include: race (white [referent] black, and other); sex (female [referent], male); region of residence at baseline (northeast [referent], northcentral, south, west); parents’ highest education in 1997 (<= high school degree [referent], some college, 4-year college degree or higher), parental wealth in 1997 (coded in thousands of constant 2010 dollars), number of siblings in household at baseline, and family structure in adolescence (two parent biological [referent], single parent, step family, other family structure). We also capture parental attachment through questions about respondent’s relationship with their parents, which may suppress the association between debt and boomeranging. Respondents are occasionally asked the extent to which they agreed with the following statements regarding their parents (measured on a 5-point Likert agree/disagree scale): (1) I think highly of him/her; (2) He/She is a person I want to be like; and (3) I really enjoy spending time with him/her. We take the average of a respondent’s available responses for each question, and then create a time-stable parental attachment scale by combining the measures into a single summed scale.
We also control for an array of time-varying variables that reflect annual measures of respondents’ PSE experiences and their social and economic characteristics as young adults. This is important, as young adults who consume more PSE (attend longer, or attend more expensive schools) accrue more debt than those who consume less PSE, and PSE characteristics may suppress the association between debt and boomeranging (Houle 2014). In addition, degree completion may be a mediator or independently predict boomeranging (noted above). PSE characteristics include degree pursued and attained (graduate school with degree attained [referent], graduate school no degree, four year institution with degree attained, four year institution no degree, two year institution with degree attained, two year institution no degree attained), current enrollment status (not enrolled [referent], currently enrolled), number of years enrolled in college, percent of years enrolled full-time, percent of years enrolled in a private institution, a weighted average of the sticker price of the cost of institutions attended over the respondents’ postsecondary career, and a dummy indicator of whether the respondent ever attended a for-profit institution.
To test whether delays in the transition to adulthood may mediate any association between debt and boomeranging, we control for annual measures that reflect youth’s life stage including: age, marital and relationship status (never married/single [referent], cohabiting, married, divorced or separated); parental status (respondent is childless [referent], respondent has a biological child). In addition, because young adults’ economic resources are likely to reflect their ability to pay down their debt, and may mediate the association between debt and boomeranging, we control for full-time employment (1=yes) and wages (measured in 2010 dollars and transformed using a natural logarithm). To the extent that emotional problems spurred by student debt may drive young adults back home, we also adjust for problem drinking and emotional distress. Problem drinking is an annual dichotomous measure coded 1 if respondents reported binge drinking in the past 30 days (five or more drinks in one sitting) or reported drinking before school or work. Emotional distress is measured biannually (2000, 2002, 2004, 2006, 2008, and 2010) with a composite score of the amount of time respondents reported: (1) being nervous, (2) feeling calm and peaceful (reverse coded), (3) felt downhearted/blue, (4) been a happy person (reverse coded), and (5) felt so down that nothing could cheer them up. Higher scores indicate more emotional distress. Survey waves where these indicators are not measured were backfilled from the next available wave.
We also adjust for contemporaneous conditions in young adulthood that are correlated with and may confound the link between debt and boomeranging. To account for the recessionary period—which was associated with a rise in student debt and boomeranging—we include a dummy coded 1 for survey years 2007–2010 and 0 for all other years. To ensure that our estimates of student debt and boomeranging are not biased by other forms of debt that are correlated with student debt, we control for mortgage debt (1=yes; 0=no) and the natural log of reported consumer debt (auto and unsecured) recorded at each YAST module. To the extent that parental support suppresses the association of interest (above and beyond parental attachment), we control for instrumental support with a dichotomous indicator coded 0 if respondents got no support from parents and 1 if respondents received financial support (other than an allowance) in the past year. We also control for urban residence (non-urban [referent], urban).
Analytical Strategy
Over 85% of the NLSY-97 sample reported living independently at some point. Those who did not were omitted from the analyses, and – among those who did – their observation period starts in the year they report living independently. The time series for residentially independent respondents end (censored) when either they return to the parental household or they reach the end of the survey period. Because our data are in yearly intervals, we elected to use discrete time proportional hazard models as opposed to Cox regression models. We conducted exploratory analyses to determine the proper functional form of the baseline hazard. Among the various options (including linear time since independence and non-linear time since independence), a fully non-parametric model (dummy variables for time) was the best fit for the data. To maintain temporal ordering of the dependent and independent variables, we set up our models whereby independent variables at time t predict boomeranging at time t+1. As such, all independent variables (including interpolated debt) are measured at the same point in time (time t)viii. We use Stata v.14, and standard errors are clustered by respondent to adjust for non-independence of observations across time.
RESULTS
Descriptive Statistics
We present descriptive statistics for the full sample and by boomerang status in Table 1. The means and standard deviations in Table 1 are interpreted as averages across all residentially independent person-year observations. Among those who become residentially independent, 59% report they boomerang 9.3% annually). Interestingly, if we were to measure boomeranging based on the household roster, only 39% of residentially independent respondents would be classified as boomerangers, suggesting that the household roster underestimates boomeranging. A likely reason for this is that the household roster misses short-term moves. Aligning with this, the risk of boomeranging is highest in the first two years of independence (11% in the first year and 23% in the second year), and then declines precipitously.

Average student debt among debtors in this sample is $17,570. While this figure is lower than the national average, this is because it represents average debt for all person-years since the respondent becomes residentially independent. For comparison, average debt among debtors is $12,777 at YAST-20, $22,358 at YAST-25, and $25,397 at YAST-30, which is consistent with national estimates (Houle 2014).
We find several key differences across respondents by boomerang status. Contrary to our expectations and the dominant narrative, young adults who boomerang report significantly less student debt than those who do. Young adults who boomerang are also more likely to be younger, black, tend to have lower PSE attainment, are less likely to attain a degree, and are more likely to attend for-profit institutions. In young adulthood, boomerang respondents are less likely to have transitioned to adult roles (marriage, parenthood) and have lower socioeconomic status than their counterparts (lower wages, lower employment) and experience more emotional distress. Overall, the descriptive statistics in Table 1 confirm recent research showing that young adult characteristics are tied to boomeranging, but do not support the overall expectation that student debt is driving young adults back to the parental home. Indeed, the bivariate association shows just the opposite—that those who boomerang carry less student debt than those who do not. To further interrogate this association, we turn to a series of discrete time event history models predicting boomeranging among college-going young adults.
Discrete Time Event History Models
In Table 2, we show results from a series of discrete time event history models. In Model 1 we show the relationship between logged student debt and the hazard of returning home, controlling only for the baseline hazard (captured with dummy variables for each residentially independent observation, but not shown) and sociodemographic background variables. In Model 2 we add PSE characteristics. We then add young adult characteristics in Model 3.

Across all models in Table 2 we find no evidence that student debt is associated with an increased risk of returning to the parental home. Indeed, the negative association observed in Table 1 is completely explained by sociodemographic background variables. As such we find no evidence to support popular claims that student debt is driving young people back home.
In model 2, we find support for claims that completion, rather than debt, may be driving people home, as postsecondary degree completion is a strong predictor of returning home. Young adults who pursue a two-year or four-year degree but do not complete the degree have the highest risk of returning home. In model 3, comparing completers to non-completers in their appropriate reference group, two-and four-year non-completers have over 40% higher risk of returning home than their counterparts in similar institutions who complete their degree ([two-year: exp..521-.159=1.43][four-year: exp..569-.206=1.44], p<.05). Moreover, this association is partially explained by young adult social and economic characteristics in Model 4, suggesting that degree non-completion increases boomeranging in part because it creates economic and social strain.
Young adult social and economic characteristics are also associated with returning to the parental home, and these patterns are in line with recent research. Young adults who have transitioned into adult roles, such as cohabiting or marital relationships are significantly less likely to return home, as are homeowners. While wages and employment status are not significant predictors of boomeranging, the coefficients are in the expected direction and these associations are significant when not controlling for the marital/relationship status variables.
So far, we’ve shown that student loan debt is not associated with boomeranging, and instead find that college completion is a strong determinant of returning home. However, student debt may be more burdensome for blacks than whites, and thus have more a stronger association with boomeranging for this group. We test this in table 3 by interacting race with student debt.

In Table 3, we find support for the argument that debt is more strongly associated with debt for black youth than it is for white youth. Given the specification of the interactions, the main effect of student debt in Model 1 represents the effect of debt on returning home among white respondents with debt, and the reference category is white respondents with no debt. The race coefficients represent the risk of returning home for black and other race respondents who have no debt, and the interaction terms represent the effect of debt on returning home among racial minority respondents. The results in Table 3 suggest that the association between student debt and boomeranging is stronger for black young adults than it is for white young adults. In Model 3, a 10% increase in student debt is associated with a 20% increase in the risk of boomeranging among blacks, but is essentially zero for whites. Interestingly, this interaction is reduced below conventional levels of statistical significance (but is still positive, p<.07) after adjusting for young adult social and economic characteristics. This suggests that student loan debt is more burdensome and has greater consequences for black youth than white youth, and that this is in part due to economic and social struggles in young adulthood. Additional models that used categories of debt (no debt, low debt [<$15,000], mid debt [$15,000–$30,000], high debt [>$30,000]) reveal that while the magnitude of the interaction effect is large for all debt categories, it is statistically significant for the low debt group only—suggesting that small amounts of debt are significantly associated with increased risk of boomeranging for black college-goers. This supports recent literature that suggests those who struggle most with loans (and are at high risk of default) have relatively low balances (Dynarski 2015), though we would caution that the effect sizes were large at higher debt levels, but may have failed to reach statistical significance due to small sample size.
Additional Analyses
We conducted additional analyses to test the robustness of our findings and to further examine plausible sources of heterogeneity in the association between student debt and boomeranging. One explanation for the null debt findings in the full sample is that debt is preventing youth from becoming residentially independent, which would bias its association with boomeranging towards zero. To test this, we show results from models that predict the risk of residential independence in Appendix A. We found that debt was positively associated with leaving home, but that this coefficient was reduced to non-significance when we adjusted for postsecondary educational experience. As such, we find little evidence that student debt is leading to a “failure to launch”, and thus that is unlikely to bias our main findings.
Another concern is that there may be some heterogeneity among young adults who boomerang, such that some young adults are “slowly detaching” and temporarily moving in and out during and after college, while others are returning home for longer periods of time after attaining independence (who we might refer to as “true boomerangers”)ix. To examine this, we use the household roster to construct a residential history and measure the number of times that respondents enter and leave the parental household. Of those who do boomerang, almost 80% return to the parental home only once. Furthermore, less than 3% of those who boomerang leave and return three or more times. This, coupled with our self-report measure that prompts respondents to consider permanent rather than temporary housing, suggests that this is unlikely to bias our findings.
Moreover, our results are consistent across additional measures and operationalizations of debt, such as the annual measures of outstanding student debt that are asked when respondents are enrolled in college and limiting our measure of debt to the YAST25 measure of debt. In addition, given the discrepancy in the estimates of boomeranging when using household rosters versus self-reports, we also tested whether our results were robust to the measure of boomeranging used. Our results were substantively equivalent across these measures. Thus, while relying on household roster data appears to underestimate the prevalence of boomeranging, it does capture many important correlates. Finally, to further examine heterogeneity in the association between debt and boomeranging, we tested whether the association differed by completion status or for-profit attendance, as recent research suggests that college non-completers and for-profit attendees may struggle with debt (Looney and Yannelis 2015). We also tested whether the association varied by gender, socioeconomic background, or other college characteristics. Further analyses revealed no support for the hypothesis that the link between debt and boomeranging varied across these groups, suggesting that student loan debt is racialized, and has greater negative consequences for black youth than other social groups.
DISCUSSION
Life course scholars have argued that residence with parents in young adulthood is a sign of stunted development, and a problematic reversal of one of the core aspects of the transition to adulthood (Sandberg-Thoma, Snyder and Jang 2015, Sassler, Ciambrone and Benway 2008, South and Lei 2015, Stone, Berrington and Falkingham 2014). A growing population of young people who attend postsecondary institutions, coupled with rising costs and debt, has raised popular and scholarly concerns about the impact of student debt and college experiences on boomeranging. In this study, we contribute to this small but burgeoning area of research and test three claims regarding the link between student debt and boomeranging: first, that student debt increases the risk of boomeranging because it creates economic strain, increases the risk of college non-completion, delays adult transitions, and undermines mental health. Second, that the association between debt and boomeranging is stronger for blacks than whites, for whom debt is more burdensome due in part to discrimination and hardship in credit, college, and labor markets. Third, that college completion, rather than debt, is most consequential for boomeranging. We find support for the second and third arguments, and find little evidence that student debt is linked to boomeranging in the total population.
Though our main findings do not align with popular claims about student debt, they are in line with recent literature that has found null or mixed findings regarding the effect of debt on transition to adulthood (Addo 2014, Houle and Berger 2015). These mixed findings likely reflect that student debt is, as Dwyer and colleagues (2011, 2012) note, a “double-edged sword” —on the one hand a valuable resource to help bridge the gap between their resources and rising costs, but on the other hand a burden that must be repaid, which may be more challenging for some groups than others. In other words, rising college costs and debt have made college a riskier proposition for some groups than others.
To this end, our findings, coupled with recent research on racial disparities in debt, suggests that taking on debt is more consequential for black young adults than for white young adults. Black students are both more likely to have trouble paying down debt, and may be more likely to drop out of college in response to high debt burdens than whites (Jackson and Reynolds 2013). Given that blacks experience lower labor market returns to college than whites (Gaddis 2015), while also facing higher debt burdens and dropout risk, black young adults take a great deal more risk in enrolling in college, and reap fewer rewards to that risk. This growing body of evidence suggests that rising debt may contribute to growing racial differences in the transition to adulthood (Furstenberg et al. 2004), and may contribute to the fragility of the next generation of the black middle class (Addo, Houle and Simon 2016). To the extent that student debt may reinforce and reproduce racial inequalities within and across generations, future research should continue to interrogate the causes and consequences of racial disparities in debt, and heterogeneity in the consequences of debt by race.
Finally, it is also important to note that our findings demonstrate that college completion—much more so than student debt, in terms of effect size—is a key correlate of returning to the parental home. Young adults who attend either 2- or 4-year institutions and fail to achieve their degree have a significantly higher risk of returning home than their counterparts, and the coefficient size is among the largest of all model covariates. These findings are consistent with recent scholarly assertions that higher education does not have a debt crisis per se, but a completion crisis (Akers and Chingos 2016). That is, in an era of rising college costs, and amidst a deteriorating labor market, the economic stakes of college completion are high. In this environment, those who start but do not finish college are in a vulnerable position, and as we show are at an elevated risk of ending up on their parents’ doorstep. Although we do not find an association between for-profit attendance and debt, the coefficient is in the expected direction, and may fail to achieve statistical significance because only a very small proportion of respondents attend for-profit institutions. Small sample size may also explain why we do not find evidence for an interaction effect of for-profit attendance by student debt. Moreover, consistent with prior research, we find that young adults’ transition into adult social roles (i.e., marriage), homeownership, and labor market success are negatively associated with boomerang risk. As such, this suggests that broader demographic changes in the transition to adulthood play a large role in shaping returns home among college-going youth (Fry 2016, Houle and Berger 2015).
This is the first study to our knowledge to examine the link between student debt, college completion, and boomeranging using longitudinal survey data from a contemporary cohort of young adults that has record levels of student debt, but it is not without limitations. First, our student debt measure is limited to three time points, and thus we may miss annual variation in student debt, which could bias our results downward. However, given that our results are robust when using the annual measure of student debt when respondents are in college, and we do not expect student debt to fluctuate dramatically between observations, this is unlikely to severely bias our results. Second, measurement bias in our boomeranging measure (recall and social desirability), is a concern, though our results are consistent with the household roster measure. Third, it is possible that young adults in our sample may not have been residentially independent long enough to observe an association between debt and boomeranging. However, we find this to be unlikely, because 1) most young adults who return home do so very quickly after attaining residential independence; and 2) we find no evidence for an interaction between student debt and time since residential independence. However, future research should continue to follow this cohort as they age and examine potential long-term effects of student debt on adult outcomes. Finally, we advise caution in causal interpretation of our findings, as student debt is not randomly assigned, and there are likely unobserved differences between students with varying debt loads that may be associated with risk of boomeranging.
Taken together, the findings suggest that college completion, transitioning into adult social roles, and labor market success may better explain rising rates of boomeranging among college-going youth than student debt, but that student debt may be exacerbating racial inequalities in transition to adulthood outcomes. Thus, our findings suggest that downstream policies intended to alleviate debt hardship should be targeted, rather than universal—for example, that private lending markets should be better regulated to protect vulnerable students from undue burden. Upstream policies would benefit from greater focus on reducing debt burden through decreasing costs (Goldrick-Rab 2016), as well as policies and programs that promote college completion and labor market success. In sum, the rise of student debt in the U.S. has created a new form of risk for college-going young adults. For many young adults, that risk may pay off. But for others, taking this risk will create hardship that complicates the transition to adulthood and perhaps will follow young people across the life course, perpetuating social inequalities that have persisted for generations.

However, we take these hypotheses seriously and test for moderation by other social groups in the supplementary analyses section.
In supplementary analyses, we estimate the association between debt and residential independence using the full sample.
Because recall bias may create concerns for moves prior to 2003, we conduct additional analyses where we interact debt with a dummy variable for pre-2003 survey wave. The interaction is non-significant and the results were similar to results presented here.
Respondents are asked “The next questions are about living on your own – that is, being the head of your household or sharing that role equally with others. If you do not live on your own, you live in a household that is headed by someone else. What month and year did you first move out on your own for at least three months, even if you moved back in to someone else’s household after that?”
Those who have established residential independence are asked: “Did you ever move back in with your parents or into someone else’s household for at least three months after that?”
For example, for a respondent observed at age 28 is assumed to have debt levels that fall between their reported values in the YAST 25 module and YAST 30 module.
We also operationalized debt with dummy variable categorical measures (no debt, low, mid, high). The results from these models were substantively equivalent to our main findings, and model fit statistics suggested logged debt provided a slightly better fit. We report where these findings differed in the results section.
We recognize that our control variables may both be a cause and consequence of debt. To more explicitly deal with this, we conducted additional analyses where time-varying postsecondary characteristics and youth social and economic variables were lagged and leaded relative to debt. These models were substantively equivalent to the models presented here
