More than half of the incidents involved partners (spousal and nonspousal), about a fourth involved prior or estranged partners, and the remainder involved family members and relatives. The 1984 rate of nonfatal family and intimate assault was estimated at 837 per 100,000 population -- the fatal rate was 7 per 100,000 population. Fatal and nonfatal victimization rates for blacks and other races were three times the rates for whites. Fatal incidents predominantly involved handguns, and nonfatal incidents most often involved bodily force. Most nonfatal victims (66 percent) and some perpetrators (13 percent) suffered physical injuries. Data on prior police contacts suggest that family and intimate assaults occur within a context of repeated violence. Information about prior incidents might contribute to preventive efforts by identifying people at high risk of being victims or perpetrators. 6 tables, 34 references. (Author abstract)
