Analysis of Racial Disparities in the New York Police Department's Stop, Question, and Frisk Practices
In 2006, the New York City Police Department (NYPD) stopped a half-million pedestrians for suspected criminal involvement. Raw statistics for these encounters suggest large racial disparities — 89 percent of the stops involved nonwhites. Do these statistics point to racial bias in police officers’ decisions to stop particular pedestrians? Do they indicate that officers are particularly intrusive when stopping nonwhites? The NYPD asked the RAND Center on Quality Policing (CQP) to help it understand this issue and identify recommendations for addressing potential problems. CQP researchers analyzed data on all street encounters between NYPD officers and pedestrians in 2006. They compared the racial distribution of stops to external benchmarks, attempts to construct what the racial distribution of the stopped pedestrians would have been if officers’ stop decisions had been racially unbiased. Then they compared each officer’s stopping patterns with an internal benchmark constructed from stops in similar circumstances made by other officers. Finally, they examined stop outcomes, assessing whether stopped white and nonwhite suspects have different rates of frisk, search, use of force, and arrest. They found small racial differences in these rates and make communication, recordkeeping, and training recommendations to the NYPD for improving police-pedestrian interactions.
