Comparing Military and Civilian Rape Rates
To place military rape rates in context, it is valuable to compare them with civilian rates. Comparisons of the crime rates of civilian and military populations during peacetime periods in 1986–92 reveal that contemporary peacetime rates of rape by American military personnel are actually lower (controlling for age and gender) than civilian rates. However, the data also indicate that peacetime military rape rates are diminished far less from civilian rates than are military rates for other violent offenses. This “rape differential” is also reflected in the World War II data: U.S. Army rape rates in Europe climbed to several times the U.S. civilian rates for that period, while military rates for other violent crimes were roughly equivalent to civilian rates. Thus, in both contexts studied, a rape differential exists: the ratio of military rape rates to civilian rape rates is substantially larger than the ratio of military rates to civilian rates for other violent crimes.

Rep. Jane Harman, D-California, spoke before a House panel investigating the way the military handles reports of sexual assault. . . "My jaw dropped when the doctors told me that 41 percent of the female veterans seen there say they were victims of sexual assault while serving in the military," said Harman, who has long sought better protection of women in the military.
. . . The Government Accountability Office released preliminary results from an investigation into sexual assaults in the military and the Coast Guard. The GAO found that the "occurrences of sexual assault may be exceeding the rates being reported."
"At the 14 installations where GAO administered its survey, 103 service members indicated that they had been sexually assaulted within the preceding 12 months. Of these, 52 service members indicated that they did not report the sexual assault," the GAO said.

An official Department of Defense report states that, “Thirty percent of female veterans in a recent survey reported rape or attempted rape during active duty. Thirty-seven percent of women who reported a rape or attempted rape had been raped more than once; fourteen percent of the victims reported having been gang raped” (Department of Defense, 2002). This is a disturbing reality during a time when 15 percent of our nation’s armed forces are female, with more than 204,500 American women serving in the military. The November 23, 2003, article in the Denver Post, “Protect Women in Military,” reports that,
“Nearly one-third of the women in the military have reported a rape or attempted rape, compared with 18 percent in the civilian world. http://www.offourbacks.org/WomMilBack.htm.******
