Extended Data Figure A.3. Average ${\mathrm{P}\mathrm{M}}_{2.5}$ concentration across ZCTAs where different racial/ethnic groups are overrepresented:

a, Distribution of ${\mathrm{P}\mathrm{M}}_{2.5}$ across five different maps each showing the ZCTAs where one race/ethnicity group is overrepresented for 2000. b, Distribution of ${\mathrm{P}\mathrm{M}}_{2.5}$ across five different maps each showing the ZCTAs where one race/ethnicity group is overrepresented for 2016. We also include an video that shows the change in the distribution of ${\mathrm{P}\mathrm{M}}_{2.5}$ concentration levels across the five maps from 2000 to 2016 (videos 2 and 3).
