Review of Chicago Police Department’s “Gang Database”

April 11, 2019

Summary

The Public Safety Section of the City of Chicago’s Office of Inspector General (OIG) concluded a review of the Chicago Police Department’s gang-related data, commonly referred to by the public as the “gang database.”

Executive Summary

OIG’s review found that while the Chicago Police Department (CPD) deploys a host of strategies, tactics, and technology in relation to gangs, it does not have a unified, stand-alone “gang database” as publicly perceived. Instead, the Department collects and stores information on individual and geographic gang involvement through a multitude of internal databases, forms, visualization tools, and repositories. CPD also receives gang-related data generated by external agencies.
