Data sources.

Neighborhood variable	Source	Level	Methodology
Closest recreation site distance (mi)	Nashville Open Data Portal, Nashville Metro Parks and Recreation website	Exact coordinates	-2016 dataset cleaned to include only public parks, greenways, public playgrounds, pools, and community centers -Baseline dataset generated by removing all sites established after 2011 -Recreation site entry points generated in ArcMap by intersection with road network -Measures generated through network analysis in ArcMap
Number of recreation sites within 0.5 mi network buffer
Number of crimes within 0.5 mi linear buffer	Metro Nashville Police Department	Exact coordinates	-Datasets included all incidents reported to the MNPD annually -Only personal safety crimes (e.g., assault, burglary, harassment) were included, consistent with our prior work14 - Incidents excluded if missing coordinates -Measure was highly associated with more sensitive kernel density estimate of crime by pairwise correlation (0.96, p<0.001)
Stray dogs per sq mi	Nashville Metro Animal Care and Control	Zip code	-Annual stray dog counts adjusted for zip code total land area
Income inequality (Gini index)	Census Population Estimates Program	Census tract	-Gini index connected with participant addresses by census tract
