bOperationalization of the guideline adherence categories have been described in Table 1.
cNeighborhood deprivation index was calculated using 2010 census tract data, using principal component analysis with for six variables: percent of residents with less than a high school diploma, percent of residents with household incomes below 100% of the federal poverty level, percent of residents who are unemployed, and median household income. The score was standardized to have a mean of 0 and SD 1. Lower values of the index indicate lower deprivation and higher values indicate higher deprivation.
dChange in income inequality was measured using the 2005–2009 and the 2012–2016 Gini coefficient of income distribution to estimate the absolute percent change in income inequality percent change, scaled to 10. The Gini coefficient of income distribution can range from 0 (prefect equality) to 100 (perfect inequality), thus, a 1-unit change represents a 10% increase in inequality.
eGentrification was operationalized using data from the 2000 decennial census and the 2006–10 American Community Survey, to calculate an index that captured percent change of college or more educated adults aged 25 or more, number of residents living below the federal poverty line, and median household income. Interpretation is based on a 1-unit change, with higher values indicate greater gentrification.
