Teen gangs are a hot issue in the United States. This volume shows the international scope of the phenomenon today. Gang activity in 14 countries, including the United States, is discussed within the larger framework of social and economic conditions. Each chapter explains the nature of the gang activity in that country; touches on the causes, such as poverty, marginalization, and self-identity problems; and heavily emphasizes the responses, including education and community-based intervention. Students and researchers will find a wealth of current information on teen gangs to mine and use for comparisons.
