Residential Mobility, Brownfield Remediation, and Environmental Gentrification in Chicago
研究芝加哥社区数据发现，棕地清理后黑人居民比白人居民更可能搬离，导致种族与污染的相关性增强，表明仅清理污染而不考虑居住流动性无法纠正环境不公。
We examine whether moving behavior contributes to the correlation between race and pollution using a residential sorting model and data on neighborhood demographics in Chicago. We find that black residents are less likely to stay and thus more likely to be displaced compared with white residents in neighborhoods after brownfields are cleaned up, contributing to environmental gentrification. This provides evidence that race and pollution become increasingly correlated because of moving behavior, with people of color less likely to move toward cleaner neighborhoods. Cleaning up pollution without a policy that acknowledges residential mobility may thus fail to correct environmental injustice. 2 These data are publicly available at the City of Chicago's Department of Planning and Development (https:// www.chicago.gov/city/en/depts/dcd/supp_info/community_ area_2000censusprofiles.html) and the Chicago Metropolitan Agency for Planning (https://datahub.cmap.illinois.gov/ dataset/2010-census-data-summarized-to-chicago-community-areas).
