The survey gathered data from 254 criminal justice agencies, community service agencies, and other organizations in 45 cities and 6 institutional sites. The analysis focused on five types of program strategies: community organization, social intervention, provision of opportunities, suppression, and organizational development and change. The cities were also characterized as having either chronic or emerging gang problems. Findings showed that suppression and social intervention were the most prevalent strategies, but other approaches should be the dominant strategies. Thus, results showed the importance of a combination of community organization and the provision of opportunities. In addition, the crucial components of the problem of youth gangs are economic deprivation, lack of opportunities, social disorganization, and the failure of community institutions. Tables.
