Community Safety and Violence

This study will describe, estimate, and explore the effectiveness of community-centered safety models (CCSMs)-including co-response, alternative response, and community violence intervention modalities-implemented across U.S. municipalities to prevent community violence among youth and young adults (YYA). Specifically, the investigators will (1) describe CCSM implementation using implementation-science methods, (2) estimate CCSMs' impacts on community-violence outcomes using quasi-experimental methods, and (3) explore operational and contextual factors associated with stronger or weaker effects.
