Analyzing Racial Disparities in LAPD Stops

Under RIPA, California police departments are required to record data on stops, searches, demographics, and outcomes from these encounters.


The Racial and Identity Profiling Act (RIPA) of 2015 was enacted in order to better identify and mitigate race-based and identity-based bias in policing. The law requires California police departments to record data on stops made by police officers, including fields such as perceived identity and demographics, reasoning for stops and searches, and the outcome of each encounter.

Research Project

Status: complete

The Los Angeles Police Department (LAPD) RIPA Board requested that Dr. Emily Owens conduct an analysis of the RIPA data and provide a report to the LAPD Commission in order to better understand any patterns that the data revealed. This report provides a place-based analysis of all stops made by the LAPD from July 2018 – October 2019.
