The Extent and Context of Rape and Sexual Assault

Our knowledge about the extent and context of rape and reasons for it comes from three sources: the FBI Uniform Crime Reports (UCR) and the National Crime Victimization Survey (NCVS), both discussed in Chapter 8 "Crime and Criminal Justice", and surveys of and interviews with women and men conducted by academic researchers. From these sources we have a fairly good if not perfect idea of how much rape occurs, the context in which it occurs, and the reasons for it. What do we know?

According to the UCR, which are compiled by the Federal Bureau of Investigation (FBI) from police reports, 88,767 reported rapes (including attempts, and defined as forced sexual intercourse) occurred in the United States in 2010 (Federal Bureau of Investigation, 2011). ^[2] Because women often do not tell police they were raped, the NCVS, which involves survey interviews of thousands of people nationwide, probably yields a better estimate of rape; the NCVS also measures sexual assaults in addition to rape, while the UCR measures only rape. According to the NCVS, 188,380 rapes and sexual assaults occurred in 2010 (Truman, 2011). ^[3] Other research indicates that up to one-third of US women will experience a rape or sexual assault, including attempts, at least once in their lives (Barkan, 2012). ^[4]A study of a random sample of 420 Toronto women involving intensive interviews yielded an even higher figure: Two-thirds said they had experienced at least one rape or sexual assault, including attempts. The researchers, Melanie Randall and Lori Haskell (1995, p. 22), ^[5] concluded that “it is more common than not for a woman to have an experience of sexual assault during their lifetime.”

Studies of college students also find a high amount of rape and sexual assault. About 20–30 percent of women students in anonymous surveys report being raped or sexually assaulted (including attempts), usually by a male student they knew beforehand (Fisher, Cullen, & Turner, 2000; Gross, Winslett, Roberts, & Gohm, 2006). ^[6] Thus at a campus of 10,000 students of whom 5,000 are women, about 1,000–1,500 women will be raped or sexually assaulted over a period of four years, or about 10 per week in a four-year academic calendar. TheNote 4.33 "People Making a Difference" box describes what one group of college students did to help reduce rape and sexual assault at their campus.
