RA Rural Area, LD Low Density, UA Urban Area. ADI groups are based on national percentile ranks using equal intervals; values in parentheses indicate group upper bounds. Black and Hispanic population shares were grouped using natural breaks (Jenks). Population counts are from the 2016–2020 ACS and were used for population-weighted accessibility analyses.
