National Justice Database

The Justice Database is the nation’s first database tracking national statistics on police behavior, including stops and use of force, and will standardize data collection across many of the country’s police departments

Join The National Justice Database

Creating a national justice database wasn’t our idea.

In fact, it was a major city police chief who actually suggested that such a database be created to help law enforcement professionals, officers, supporters, changemakers, and others better understand how to best serve and protect.

From that idea, offered more as a question of possibility than a declaration of intention, our organization expanded its services and began developing the National Justice Database.

By integrating crime data, demographics from the U.S. Census and American Community Survey, and police behavioral data, the NJD provides a unique analytic opportunity to determine what portion of racial disparities results from police behavior (as opposed to, say, educational or income disparities). These data are further integrated in many cases with psychological surveys of officers and residents, allowing for the first-ever chance to diagnose what role bias (implicit or explicit), job stress, and other psychological factors play in the production of disparate policing outcomes. All of this is made possible with the speed and automation of software developed in collaboration with Google and the support of other key philanthropic partners.

By combining our deep understanding of law enforcement with powerful analytics and Google’s technology, the NJD is poised to inform policy and practice about how best to:

  • Equip law enforcement to do their jobs safely.
  • Pinpoint instances of poor police behavior, and
  • Empower communities to trust their public safety nationwide.

Combining Many Academic Disciplines

Focusing on what causes racial disparities in policing and how one can measure these disparities, the Justice Database uses tools taken from sociology, demography, public policy, criminology, psychology, and behavioral economics. This project capitalizes on existing research collaborations between Center for Policing Equity and law enforcement departments across the United States to produce a mixed-methods approach to understanding what produces racial inequality in policing.
