NIJ FY 2026 Research and Evaluation on Violent Crime: Gangs and Organized Criminal Groups (Domestic and Transnational)

This grant funds research and evaluation projects on gang and organized-criminal-group violent crime, both domestic and transnational, that inform law-enforcement strategies and related national policies. It supports rigorous evaluations of new or existing approaches to reduce such violence, especially those led by or collaborating with law-enforcement agencies, using designs such as randomized trials, mixed methods, quasi-experimental or matched comparisons.
