Gun Violence
In cities across America, communities face high rates of gun violence and significant harm caused by the criminal justice system – both of which disproportionately impact communities of color.
Our nation’s public safety crisis is a gun violence crisis, and for some communities, this crisis is worse than ever before. In fact, in 2020, Black Chicagoans experienced more homicides per resident than any year on record. This violence was heavily concentrated: in 2020, the gun homicide rate in Chicago’s four most violent police districts was 26 times higher than in the four safest police districts. In 1991, the rate for those same districts was 13 times higher — meaning the safety gap has doubled in Chicago’s most vulnerable neighborhoods since the 1990s.
There is reason for hope that we can turn the tide: From the peak of the early ‘90s to 2019, Los Angeles and New York have slashed their homicide rates by 77% and 88%, respectively.
The Crime Lab works with cities and community-based groups to generate evidence on interventions that prevent gun violence, including increasing public access to gun violence data, implementing behavioral science-informed interventions, and connecting individuals with employment, housing, and other supports.
Our evaluation of READI Chicago found that participants referred to the program by outreach workers in their community were 79% less likely to be arrested for shootings and homicides.
In partnership with the City of Chicago and dozens of community organizations, the Crime Lab created the Violence Reduction Dashboard, which led the nation in providing unprecedented public access to near real-time data on gun violence.

Unforgiving Places: The Unexpected Origins of American Gun Violence
Crime Lab Pritzker Director Jens Ludwig authored a book that argues the lack of progress in reducing gun violence ultimately stems from our having misunderstood the nature of the problem, and that behavioral science gives us a new way to understand – and solve – gun violence in America.
