Inequalities in air pollution exposure are increasing in the United States	2020-07-15		.txt	text/plain	4688	266	56	For each racial/ethnic group (White, Black, Asian, and Hispanic) 1 , we construct a map that shows only zip code tabulation areas (ZCTAs) where the race/ethnicity is most present 2 To quantify these differences in exposure, we compute the population-weighted average PM 2.5 concentration for every racial/ethnic population (please see Methods) (Extended Data figure A.4a). However, the CoV shows that the variation in air pollution exposure among racial/ethnic groups relative to its mean increased from 0.17 3 Ranking the ZCTAs for a particular race is done by using the population fraction of the race in every ZCTA to split them into 100 quantiles by using percentiles. . https://doi.org/10.1101/2020.07.13.20152942 doi: medRxiv preprint figure 4 , disparities in air pollution exposure among racial/ethnic groups and income groups are increasing.	./cache/cord-102783-f8i20twx.txt	./txt/cord-102783-f8i20twx.txt
