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.
