Multiple independent studies have shown substantial reductions in violence. Here are a few highlights:
An extensive evaluation of the Cure Violence program in 2 communities in New York City is currently being conducted by John Jay College of Criminal Justice Research and Evaluation Center. Although the complete evaluation is ongoing, there have been several reports released with important findings.
- 18% reduction in killings compared to 69% increase in controls
- 14% reduction in attitudes supporting violence, with no change in controls
- Young men in Cure Violence zones reported Increased confidence in police and increased willingness to contact police
A 2012 CDC/Johns Hopkins evaluation of 4 communities in Baltimore.
- 56% reductions in killings and 34% in shootings in one community
- Reductions across all 4 communities
- 276 conflict mediations
- Reductions spread to surrounding communities
- Norms on violence were changed – people in program site were much less likely to accept the use of a gun to settle a dispute; 4 times more likely to show little or no support for gun use.
A 2009 NIJ/Northwestern University evaluation analyzed 7 communities in Chicago.
- 41% to 73% reductions in shootings
- 40% reduction/cooling of hot spots
- 100% reductions in retaliation homicides in 5 of 8 communities
- “Overall, the impact of the CeaseFire Program is significant and moderate-to-large in size.”
- “In every program area there was a substantial decline in the median density of shootings following the introduction of CeaseFire.”
A 2013 McCormick Foundation/University of Chicago/UIC quantitative and a qualitative evaluation of the 2012/2013 CeaseFire illinois/Cure Violence program covered two Chicago neighborhoods.
- 31% greater decrease in killings
- 1% greater decrease in total violent crimes (including domestic violence),
- 19% greater decrease in shootings
- CeaseFire high-risk participants reported decreased involvement in crime and violence,
In New York City, a 2010 BJA/Center for Court Innovation evaluation analyzed the program in Crown Heights, Brooklyn.
- 20% lower shootings compared to control
- More than 100 mediations involving more than 1,000 people
- Average monthly shooting rates decreased by 6%, while increasing in the three comparison areas between 18% and 28%
This report presents a comprehensive evaluation of the Cure Violence initiative implemented in Trinidad and Tobago from July 2015 to August 2017. It describes the evaluation’s methods and findings and includes three main components: a process evaluation, impact evaluation, and cost-effectiveness analysis.
- 45% reduction in violent crime rate
- 23% reduction in calls for police
- Reduction in hospital admissions
- “They really are suggestive of a strong impact.” Nicholas Corsaro, Evaluator
- “Our study actually showed really powerful effects.” Ed Maguire, Lead Evaluator
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.
