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.
Based on the latest statistics compiled by the Federal Bureau of Investigation (FBI), the national violent crime arrest rate declined 38 percent overall between 1988 and 2018, but the steepest declines were observed among youth ages 10 to 14 (–53%) and 15 to 17 (–54%). The arrest rate for 18-20 year-olds dropped 47 percent while the arrest rates for adults ages 21-24 and 25-49 declined 42 percent and 23 percent, respectively.
Was the presence of the MAP initiative in some NYCHA developments associated with greater improvements in crime and victimization outcomes compared with the same outcomes in NYCHA developments not involved in MAP? The results presented here do not answer the question in full, but they offer an early look at efforts by the research team to generate more precise answers. Additional analyses are needed to rule out competing explanations and to examine the complex series of relationships among all the study’s variables. Based on the preliminary findings in this report, however, the results of MAP to date may be considered promising.
This second in a series of reports about the evaluation of the New York City Mayor’s Action Plan for Neighborhood Safety (MAP). This Evaluation Update: summarizes the goals and methods used to evaluate the Mayor’s Action Plan; describes the quasi-experimental design used to test the outcomes and impacts of MAP as well as the data sources assembled by the research team and how they are used; and portrays a logical framework the research team used initially to identify causal pathways through which various elements of MAP were intended to achieve their desired effect.
To evaluate the New York City Mayor's Action Plan for Neighborhood Safety (MAP), an initiative to improve the safety of public housing developments, researchers estimated the counterfactual (no intervention) by selecting a set of comparison housing developments not involved in the initiative. The study relied on the statistical method known as propensity score analysis (PSA) to select the comparison group.
