In New York, a study by the John Jay College of Criminal Justice found that violence interrupters helped reduce crime in the East New York and South Bronx neighborhoods.
Surveys of New York City public housing residents suggest that changes in some public safety outcomes might be mediated by gains in community well-being, social cohesion, engagement with government, and citizen trust in the competence of government agencies and actors. As communities become more tightly connected and more supported, they may experience gains in public safety.
As part of an evaluation of the New York City Mayor’s Action Plan for Neighborhood Safety (MAP), researchers from John Jay College of Criminal Justice collaborated with survey specialists from NORC at the University Chicago to collect data from two probability samples of residents in public housing developments in New York City. One sample of residents came from communities involved in the MAP initiative. A second sample was from statistically matched housing developments not involved in MAP.
