Although national estimates vary according to survey methodologies employed, the results are unequivocal in showing that IPV remains a widespread experience among American women. According to the National Violence Against Women Survey (NVAWS), women’s lifetime prevalence of physical assault victimization by an intimate partner is about 22 percent. Lifetime prevalence is 7.7 percent for intimate partner rape and 4.8 percent for intimate partner stalking. NVAWS data also indicate that 5.3 million victimizations occur annually for adult women. In 1997, nearly 1.5 million women experienced approximately 4.5 million violent acts by intimate partners (Tjaden & Thoennes, 2000a). Estimates from the National Crime Victimization Survey (NCVS) indicate that women suffered nearly 600,000 nonfatal violent victimizations by an intimate partner in 2001 and that 85 percent of IPV incidents were against women (Rennison, 2003). Over a lifetime, as shown in the results of the NVAWS, the prevalence of IPV for women is triple the prevalence for men (Tjaden & Thoennes, 2000b).
