Abstract

This project links administrative census microdata to spatially continuous measures of particulate pollution (PM2.5) to first document and then decompose the key drivers of convergence in black-white pollution exposure differences. We use quantile regression to show that a significant portion of the convergence in Black-White exposure is attributable to differential impacts of the Clean Air Act (CAA) in Black and White communities. Areas with larger Black populations saw greater CAA-related declines in PM2.5. We show that the CAA can account for over 60 percent of the racial convergence in PM2.5 pollution exposure in the United States since 2000.
