This report presents an overview of gang research and programs in the United States and examines how gangs form and why youth join them. It is based on information on research findings and prevention strategies disseminated by the Office of Juvenile Justice and Delinquency Prevention as part of its comprehensive anti-gang initiative. This report describes how community members can start assessing their gang problems and enhance prevention and intervention activities to help prevent delinquency and gang violence. It identifies promising and effective programs for gang prevention. Illustrations. This is a print on demand edition of an important, hard-to-find publication.

The United States has seen rapid proliferation of youth gangs since 1980. During this period, the number of cities with gang problems increased from an estimated 286 jurisdictions with more than 2,000 gangs and nearly 100,000 gang members in 1980 (Miller, 1992) to about 4,800 jurisdictions with more than 31,000 gangs and approximately 846,000 gang members in 1996(Moore and Terrett, in press). An 11-city survey of eighth graders found that 9 percent were currently gang members, and 17 percent said they had belonged to a gang at some point in their lives (Esbensen and Osgood, 1997).Other studies reported comparable percentages and also showed that gang members were responsible for a large proportion of violent offenses. In the Rochester site of the OJJDP-funded Program of Research on the Causes and Correlates of Delinquency, gang members (30 percent of the sample) self-reported committing 68 percent of all violent offenses (Thornberry, 1998). In the Denver site, adolescent gang members (14 percent of the sample) self-reported committing 89 percent of all serious violent offenses (Huizinga, 1997). In another study, supported by OJJDP and several other agenciesand organizations, adolescent gang members in Seattle (15 percent of the sample) self-reported involvement in 85 percent of robberies committed by the entire sample (Battin et al., 1998).This Bulletin reviews data and research to consolidate available knowledge on youth gangs that are involved in criminal activity. Following a historical perspective, demographic information ispresented. The scope of the problem is assessed, including gang problems in juvenile detention and correctional facilities. Several issues are then addressed by reviewing gang studies to provide aclearer understanding of youth gang problems.An extensive list of references is provided for further review.

This systematic analysis of the youth gang problem in the USA focuses on current patterns of gang behaviour, with reference to historical and cross-cultural dimensions. The author integrates his own theory and practices with material on research programmes set up to address the problem.

This edited book significantly contributes to the knowledge on how to address gang problems from a broad community perspective, which takes into account criminal justice agencies, social service providers, and community leaders, along with police, who have implemented collaborative anti-gang policies and practices. As community-wide efforts become more common, it is increasingly important to investigate effective strategies to address social problems. Beyond Suppression: Community Strategies to Reduce Gang Violence explores a demonstration project of one state’s efforts to reduce gang and youth violence through use of a comprehensive initiative, the Comprehensive Gang Model (CGM). The relevance of the CGM as a conceptual framework to guide gang policy and practice is illustrated throughout the book, and tailored gang reduction strategies derived from that framework and rooted in the ecological constitution of communities are showcased. The chapters highlight implementation strategies employed by various communities using a case study methodology that assists in garnering an in-depth perspective of implementation issues and key dimensions of the CGM. This book answers important questions about how communities operationalize the CGM. The results of these investigations are important for scholars, learners, and practitioners who seek to address gang violence using a customized response.

This publication provides comprehensive guidance on how to implement GVI step by step, discussing the role and responsibilities of the core representatives in law enforcement, the community, and social services. It explains the logic and basics of the strategy before taking the reader through the initial planning stages, design, and execution of all key strategy elements, such as problem analysis and the call-in. This guide also includes methods to maintain program integrity and ensure sustainability in the long-term.
