Estimates from the National Crime Victimization Survey (NCVS) indicate that in 1998 about 1 million violent crimes were committed against persons by their current or former spouses, boyfriends, or girlfriends. Such crimes, termed intimate partner violence, are committed primarily against women. About 85% of victimizations by intimate partners in 1998, about 876,340, were against women. Intimate partner violence made up 22% of violent crime against women between 1993 and 1998. By contrast, during this period intimate partners committed 3% of the violence against men. Women experienced intimate partner violence at lower rates in 1998 than in 1993. From 1993 to 1997 the rate of intimate partner violence fell from 9.8 to 7.5 per 1,000 women. In 1998 the rate was virtually unchanged from that in 1997 (7.7 per 1,000 women). Males experienced intimate partner violence at similar rates in 1993 and 1998 (1.6 and 1.5 per 1,000 men, respectively). In 1998 about 1,830 murders were attributable to intimate partners, down substantially from the 3,000 murders in 1976. This report updates findings presented in Violence by Intimates (March 1998, NCJ 167237) and provides more complete statistics of intimate partner violence against men. (Author abstract)
