Résumé
This report found that some prevention programs work, some do not, some are promising, and some have not been tested adequately. Given the evidence of promising and effective programs, the report finds that the effectiveness of government funding depends heavily on whether it is directed to the urban neighborhoods where youth violence is highly concentrated. Substantial reductions in national rates of serious crime can only be achieved by prevention in areas of concentrated poverty, where the majority of all homicides in the nation occur, and where homicide rates are 20 times the national average.
