Inequality and Policing
Joint with M. Keith Chen, Elicia John, Emily Owens, and Yilin Zhuo, "Smartphone Data Reveal Neighborhood-Level Racial Disparities in Police Presence," equal authorship, https://arxiv.org/abs/2109.12491, preparing for 3rd round review at Review of Economics and Statistics
While extensive, research on policing in America has focused on documented actions such as stops and arrests—less is known about patrolling and presence. We map the movements of over ten thousand police officers across twenty-three of America's largest cities by combining anonymized smartphone data with station and precinct boundaries. Police spend considerably more time in Black neighborhoods, a disparity which persists after controlling for density, socioeconomics, and crime-driven demand for policing. Our results suggest that roughly half of observed racial disparities in arrests derive from disparities in exposure, and that supervisor (but not officer) diversity reduces this.
