For courses in Gangs and Juvenile Delinquency. Applicable for students, academics, and practitioners, this text presents an overview of the prominent quantitative and qualitative data that exists on gangs. Academically sound, it synthesizes gang research into a format that is understandable for students and offers a balance between clarity and rigor. Placing a clear distinction between gangs and gang members, it highlights the differences between individual and group perspectives and encourages a richer understanding of the phenomenon. More visual than competing texts, it uses learning boxes to highlight notable research projects and special topics. Separate chapters are devoted to current issues such as race/ethnicity; gender; prison gangs; and prevention and intervention.
