This NIJ Research Report presents findings from a survey of 8,000 U.S. women and 8,000 U.S. men about their experiences as victims of intimate partner violence (rape, physical assault, and stalking). Respondents were asked detailed questions about the characteristics and consequences of their victimization during their lifetime and the past 12 months, including the rate of injury among rape and physical assault victims, their use of medical services, and their involvement with the criminal justice system. Extent, Nature, and Consequences of Intimate Partner Violence: Findings From the National Violence Against Women Survey also summarizes the survey's findings on victimization rates among women and men, specific racial and ethnic groups, and Hispanics and non-Hispanics.
