Official statistics on child abuse and wife abuse indicate that women, blacks, minorities, and the poor are overrepresented as victims of domestic violence. Data also show that overrepresentation of blacks among homicide victims. In fact, homicide is the leading cause of death of black men and women aged 25 to 34. Various models have been proposed to explain the violence. Research has identified many factors that appear to be associated with both processes, particularly family stress, limited resources, and existence of multiple problems. In cases when homicide occurs as a direct result of violence or in retaliation to violence, the links may be causal in both directions. Thus, efforts to reduce the incidence of family violence may prevent some homicides. Primary prevention techniques might include educational programs for parents and children, stress reduction efforts through neighborhood support teams, and family counseling or therapy. Secondary and tertiary prevention techniques are also needed. Research recommendations and 49 references.
