Notes. Population and demographic data were obtained from the American Community Survey, 2015–2019 5-year estimates. Street length was obtained from calculations using OpenStreetMap (Boeing, 2019). We calculated proportion tree cover using 1 m land cover classification data generated by the Chesapeake Conservancy, from 2013 to 2014 NAIP imagery (Land Cover Data Project 2013/2014 - Chesapeake Conservancy, 2022). Shootings were 2015–2020 fatal and non-fatal incidents obtained from the Gun Violence Archive (Gun Violence Archive, 2021).

Omits census tracts for which ICE estimates could not be calculated.

Weighted by census tract population.
