This NIJ Research Report presents a systematic analysis of the sexual victimization of college women by examining two national-level surveys that used two different survey methods: the National College Women Sexual Victimization Study and the National Crime Victimization Survey. The report—cosponsored by the National Institute of Justice and the Bureau of Justice Statistics—assesses the extent and nature of the sexual victimization of college women. Based on the study findings, it is estimated that more than 350 rapes per year may occur on a campus with a population of 10,000 female students.
