Policy and Program Evaluation

We work with government agencies and community-based partners to rigorously evaluate gun violence intervention programs and criminal justice policy reforms.

 Across every project or partner, we work to generate high-quality research about the factors driving public safety trends and identify evidence-based interventions to save lives. Access to good and unbiased data is the common denominator for strong evaluation, which is why we pursue data-sharing agreements with public agencies and seek to make our own data publicly available whenever possible. We focus on policies and programs that are supporting the communities and individuals most impacted by gun violence and criminal justice system harms. 

From leading randomized controlled trials — the gold standard in research — to evaluating historical and real-time data, the Crime Lab uses a variety of methods to rigorously evaluate policies and interventions.
