A 2017 evaluation of the Cure Violence program in Philadelphia found significant reductions in violence associated with the program.


  • 30% reduction in shootings (comparing the 24 months before the implementation of CeaseFire to the 24 months after implementation)
  • In the five hotspot areas, CeaseFire was associated with a statistically significant reduction in both total shootings (victims of all ages) and shootings of individuals between the ages of 10 and 35.
  • Although in some models comparison groups also showed reductions in shootings, these reductions were either not statistically significant or not as large as those in the CeaseFire target areas.
