Trends in PM2.5 exposure experienced and caused by racial-ethnic groups. Top panel: Total exposure to PM2.5 caused by population-adjusted group consumption (“caused”) and group exposure to PM2.5 caused by total personal consumption (“exposed”), by racial-ethnic group. Pollution inequity is the percent difference between a group’s “exposed” and “caused” bars. Each group of bars shows the emitters (A) and end uses (B) responsible for the exposure, with gray connecting lines showing relationships among emitters and end uses. Connecting lines representing < 0.04 μg m-3 are not shown. Lower-left panel: Contributions of differences in consumption (“caused”) and location-of-residence (“exposed”) to pollution inequity. Lowercenter panel: Exposure of each racial-ethnic group to PM2.5 caused by the total combined personal consumption of all groups (“exposed”; solid lines) and total-population exposure to PM2.5 caused by each group’s population-adjusted consumption (“caused”; dashed lines), 2003–2015. Lower-right panel: Pollution inequity, 2003–2015.

Inequity in consumption of goods and services adds to racial–ethnic disparities in air pollution exposure
