We examined different strategies for identifying nonfatal family and intimate assaults (FIAs) in police data. Police most often classify such incidents in the "assault" category, but they also use other crime categories. We estimated that, during 1984, 3300 FIAs (or 837 per 100,000 population) occurred in Atlanta. Of those, 77% were classified as assaults; 23% were classified in nonassault categories. Research measuring the magnitude of FIAs should take into account incidents classified in nonassault crime categories.
