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 conditional accept, Review of Economics and Statistics
Research on policing has focused on documented actions such as stops and arrests—less is known about patrols and presence. We map the neighborhood movement of nearly ten thousand officers across 21 of America’s largest cities using anonymized smartphone data. Police spend 0.36% more time in neighborhoods for each percentage point increase in Black residents. This neighborhood-level disparity persists after controlling for density, socioeconomic, and crime-driven demand for policing, and may be lower in cities with more Black police supervisors (but not officers). Patterns of police presence statistically explain 57% of the higher arrest rate in more Black neighborhoods.
