NIJ FY18 Research and Evaluation on Gangs and Gang Violence

Closing Date
NIJ is seeking applications for research and program evaluation projects that inform efforts to reduce street gang activity and violence in the United States. Gangs and gang members are responsible for a large amount of crime and violence in many localities, and are responsible for a disproportionate share in those communities most afflicted by crime and violence. NIJ will support scientifically rigorous research and evaluation projects designed to produce findings with high practical utility for gang prevention, intervention, enforcement, or reentry strategies.

NIJ FY 14 Research on Gangs and Gang Violence

Closing Date

Results from these projects should lead to better criminal justice policy, practice, and research, particularly at the local or state level, on issues surrounding gangs.​
