Enforcing Race: A Neighborhood-Level Explanation of Black-White Differences in Drug Arrests

This research investigates the source of Black-White differences in drug arrests by conducting a neighborhood-level test of the differential police scrutiny and racially discriminatory policing hypotheses. The study examines drug arrests made across 78 neighborhoods in St. Louis between 2009 and 2013. Results from the negative binomial regression analyses lend the greatest support to the racially discriminatory policing perspective. Neighborhood racial composition significantly shapes drug law enforcement practices, net of neighborhood-level violent and property crime rates, drug-related calls for service by citizens, and socioeconomic disadvantage. Specifically, findings suggest that officers engage in "out-of-place" racial profiling in drug law enforcement, as they tend to target suspects whose race is incongruent with the neighborhood racial context. Implications of the study findings are discussed.
