The graph is a line chart titled "Average PM2.5 Exposure from Electricity Generation." The y-axis, which ranges from zero to 3.5, plots the average PM2.5 exposure from electricity generation in micrograms/cubic meter/person by race/ethnicity. The x-axis spans the years 2000 to 2018. The average Black individual consistently experienced higher PM2.5 concentrations from 2000 to 2018 than the average White individual, who consistently experienced higher concentrations than the average Hispanic individual. The concentration experienced by the average Black individual decreased from about 3.22 in 2000 to 0.32 in 2018. The concentration experienced by the average White individual decreased from about 2.47 in 2000 to 0.28 in 2018. Finally, the concentration experienced by the average Hispanic individual decreased from about 1.5 in 2000 to 0.21 in 2018. Source: Researchers' calculations using data from the EPA, EIA, and ACS.
