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 title is part of The Wadsworth Professionalism in Policing Series, edited by Samuel Walker. This reader is a descriptive presentation of current practices within policing and juvenile justice (focusing on gangs) that utilize the community-policing model. By looking at specific strategies and their efficacy, the authors attempt to combat a major perceived problem with community policing; that the methodology of community policing can be subjective and nebulous, using ill-defined and misinterpreted practices. This book shows what is working for agencies across the country and how these "best practices" can be employed.

This volume provides a systematic overview of the contemporary Latin American youth violence phenomenon. The authors focus specifically on youth gangs, juvenile justice issues, and applied research concerns, providing a rounded and balanced exploration of this increasingly important topic.

In the quarter century since the first edition of this book, scholarship on gangs in general, and especially youth gangs, has grown exponentially. This massive expansion of the literature on youth gangs, especially in the past decade, warranted this expanded and updated fourth edition. The first chapter has an expanded discussion of definitional issues, plus recent data from the National Youth Gang Survey, material on the evolving economic nature of gangs, and gang use of internet and social media. The second chapter continues by examining gang violence and drug involvement, and the extent to which they are intercorrelated, with new material on victimization of gang members and gang involvement in drug use and sales. Chapter 3 focuses on racial and ethnic decadences in gangs and the important role of race and ethnicity on gang membership and gang behavior in the U.S. The fourth chapter examines female gangs and gang membership and the changes that have taken place in the nature and extent of female gang membership over time. The fifth and sixth chapters place contemporary American gangs in the historical and international perspective. Chapter 5 includes a new section on youth gangs in the new millennium, and Chapter 6 has been reorganized, particularly to reflect the burgeoning research on European and other international gangs since the turn of the millennium. Chapter 7 has been expanded to include recent developments in the actual and potential application of biosocial, psychological, and life course developmental theories to gangs. Chapter 8 provides a comprehensive, multilevel theory of gangs with updates including new propositions, and new evidence for both the new and old propositions, based on more recent work in theory development and theory testing for gangs. The ninth and tenth chapters’ revisions focus on legislative and justice system efforts to deter gang crime and membership. Chapter 10 also focuses on intervention and assistance programs outside the justice system, including discussion of the Gang Resistance Education and Training program. The final chapter concludes by considering the future of youth gangs in the U.S. and elsewhere in light of historical and cross-national evidence, theory, and experience with gang interventions and programs, considering more recent developments in those areas, and whether they justify any change and for what would be expected of the future of youth gangs.

In this book, Irving Spergel details the efforts of his Chicago youth gang project, a comprehensive, community-based model designed to reduce gang problems, including violence and illegal drug activity. He offers an in-depth description of the Little Village Gang Violence Reduction Project, revealing the successes and failures of intervention at each level: individual youths, the gang itself, and the community at large. Spergel relates how a coalition of criminal justice, neighborhood, and academic organizations_along with a team of tactical officers, probation officers, former gang leaders, and a neighborhood organization_developed strategies for dealing with hardcore violent male youths from two gangs: the Latin Kings and Two Six. This well-known project has become the model for a series of national initiatives. Policymakers, criminologists, and gang researchers will find this model valuable for assessing gang programs and reducing gang violence.

'Oxford Textbook Violence Prevention' brings together an international team of experts to provide an extensive global account of the global mortality and morbidity burden caused by violence through examining the causes of violence, and what can be done to prevent and reduce violence.

Provides an introduction to the study of gangs how we define them, what we know and not know about gangs. This title offers both a domestic and international view of processes of delinquency and gang formation and identity. It is suitable for criminal justice, sociology and social work, parole practitioners, and public defenders.

This unique volume by eminent gang researchers presents valuable new data on European youth gangs, describing important characteristics of these groups, and their similarities and differences to American gangs. Their findings from the Eurogang Research Program highlight the impact of immigration and ethnicity, urbanization, national influences, and local neighborhood circumstances on gang development in several European countries. It is an important resource on crime, delinquency and youth development for criminologists, sociologists, youth workers, policy makers, local governments, and law enforcement professionals.

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.
