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 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.

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.

Although a range of program and policy responses to youth gangs exist, most are largely based on suppression, implemented by the police or other criminal justice agencies. Less attention and fewer resources have been directed to prevention and intervention strategies that draw on the participation of community organizations, schools, and social service agencies in the neighborhoods in which gangs operate. Also underemphasized is the importance of integrating such approaches at the local level. In this volume, leading researchers discuss effective intervention among youth gangs, focusing on the ideas behind, approaches to, and evidence about the effectiveness of community-based, youth gang interventions. Treating community as a crucial unit of analysis and action, these essays reorient our understanding of gangs and the measures undertaken to defeat them. They emphasize the importance of community, both as a context that shapes opportunity and as a resource that promotes positive youth engagement. Covering key themes and debates, this book explores the role of social capital and collective efficacy in informing youth gang intervention and evaluation, the importance of focusing on youth development within the context of community opportunities and pressures, and the possibilities of better linking research, policy, and practice when responding to youth gangs, among other critical issues.
