Sexual Assault By The Numbers

Sexual assault is a pervasive issue.

Cultural factors, including societal norms, systemic inequalities, and community-specific barriers shape the prevalence and impact of sexual assault. These disparities affect how survivors experience, report, and heal from sexual assault. 

By recognizing these cultural influences, we can better understand the complexities of this issue and advocate for inclusive, community-informed solutions that meet survivors where they are.


For Coloradans, 1 in 3 people experience some form of sexual violence, in their lifetime, 80% of which take place prior to the age of 25.

  • The likelihood of repeat victimization increases, for youth who have experienced sexual violence before the age of 18.
  • Forty-two percent of victims experienced their first completed rape before the age of 18 years.
  • According to the 2019 Healthy Kids Colorado Survey Report:
    • 10.1%  of female students & 3.4%  of male students reported having been physically forced to have sexual intercourse when she/he did not want to have intercourse. 
    • 8% of surveyed students reported making unwelcome sexualized comments, jokes, gestures, or leering
    • 4% of Colorado students overall reported touching, grabbing, pinching, or otherwise handling someone in a sexual way, despite it being noted as unwanted by the victim.

Survivors with a lifetime history of rape, physical violence, or stalking by an intimate partner were more likely to report poor physical and mental health compared with those without a history of intimate partner violence.

  • Among U.S. women, the adjusted odds of experiencing asthma, irritable bowel syndrome, frequent headaches, chronic pain, difficulty sleeping, activity limitations, poor physical or mental health, and use of special equipment (e.g., wheelchair) were significantly higher for lifetime rape victims compared with non-victims.

False Reporting

  • The majority of sexual assaults, an estimated 63 percent, are never reported to the police.
  • A review of research finds that the prevalence of false reporting is between 2 percent and 10 percent. 
  • Often, victims who do report will delay doing so for a variety of reasons that are connected to neurobiological and psychological responses to their assault.

Sexual violence is a cost to society.

  • Individual victims of sexual violence incur $122,461 over a lifetime in costs associated with lost wages, health, criminal justice, and property damage
  • Sexual violence can derail a person’s education and employment, resulting in a $241,600 income loss over a lifetime
  • In 2015, the Equal Employment Opportunity Commission alone recovered $164.5 million for workers alleging harassment.
