This working paper is a descriptive analysis of homicides from 1998 to 2002 in Hayward, California. It complements earlier analyses of violence in several other California jurisdictions, including Oakland, Los Angeles and San Diego. These analyses are part of a series that RAND Corporation researchers have conducted on behalf of Project Safe Neighborhoods, which is a national initiative funded by the U.S. Department of Justice. Project Safe Neighborhoods, coordinated through U.S. Attorney’s offices, is a strategic, coordinated approach to reducing gun violence in America. The role of RAND researchers in the Hayward project is to provide research and support for the strategic planning components of the initiative. The goals of this program are to (1) increase the capacity of Project Safe Neighborhood task forces to design data-driven strategies that produce measurable decreases in firearms-related crime and (2) improve the long-term ability of federal, state, and local agencies to work together to understand, prosecute, and prevent firearms-related violent crime within their jurisdictions.
