Research into the characteristics of at-risk juveniles that contribute to violence and the patterns of behavior and neighborhood characteristics and patterns that are associated with youth violence or victimization are reviewed. The results of the studies reviewed cannot be generalized to the total population of juveniles, but the findings of these studies appear to be consistent with past research. Overall, juvenile violence is committed primarily by males and often occurs intra-racially among minority groups. The majority of juvenile offenders are 16- and 17-year-olds. Many violent offenders live in disruptive and disorganized families and communities, although the majority of youth in such environments are not involved in serious delinquency. Some recommendations are given for the prevention and control of juvenile violence. These include suggestions for dealing with gangs, guns, and high-risk juveniles. (Contains 36 references.) (SLD)
