According to the U.S. Centers for Disease Control and Prevention’s (CDC) 2010 National Intimate Partner and Sexual Violence Survey (NISVS), nearly 1 in 5 women (18.3 percent) and 1 in 71 men (1.4 percent) in the United States have been raped at some time in their lives, including completed, attempted or alcohol/drug-facilitated rape.
Forty-two percent of victims experienced their first completed rape before the age of 18 years.
In Colorado, the lifetime prevalence of sexual violence by any perpetrator for women is 23.8 percent, which is higher than the national prevalence of 18.3 percent.
The 2010 NISVS indicates the lifetime prevalence of sexual violence acts other than rape for women in Colorado is 47.4 percent, versus 44.6 percent in the nation as a whole and for men in Colorado is 26.5 percent, versus 22.2 percent for the nation as a whole.
Additionally, the CDC reports that men and women with a lifetime history of rape, physical violence or stalking by an intimate partner were more likely to report frequent headaches, chronic pain, difficulty sleeping, activity limitations and poor physical health in general compared with those without a history of intimate partner violence.
According to the 2011 Healthy Kids Colorado Survey Report, which was completed by 1,523 students from 33 schools, 9.9 percent of female students and 4.2 percent of male students reported having been physically forced to have sexual intercourse when she/he did not want to have intercourse.
While these data provide some context to the prevalence of sexual violence in Colorado, data on the magnitude of sexual violence remains incomplete. Measuring the true magnitude of sexual violence is difficult, due to issues of nondisclosure, different data collection and analysis methodologies, and the varying definitions of sexual violence.
