        Sexual Assault by the Numbers

        Just how bad of a problem is sexual assault? The reality is that we don’t definitively know; the available data can not begin to paint the complete picture of the scope of the problem. Why? Because most of the numbers we have reflect the number of crimes reported to law enforcement. But, sexual assault is one of those crimes that is still so misunderstood; we know that many victims are not reporting – either because they are ashamed, feel the assault was somehow their fault, are worried about consequences to their perpetrator (who all too often is someone known to the victim and/or an intimate partner), or because they feel that what happened was just “normal” and wasn’t a crime at all.

        In partnership with state agencies and the service providers we represent, WCASA is working toward a more comprehensive picture of sexual violence in Wisconsin.




        Burden of Sexual Violence in Wisconsin Report (2010)

        • Sexual violence is a significant public health problem impacting nearly a million people in Wisconsin. It is perhaps the most personal and invasive expression of violence that one person (or a group) can perpetrate upon another individual. Victims of sexual assault come from every walk of life, and this epidemic knows no boundaries; sexual violence affects us all. But what is the real burden of sexual violence on the communities in Wisconsin?
        • The Burden of Sexual Violence in Wisconsin Report (2010) compiles data from a variety of sources to help us articulate the impact sexual violence has at a state level, as well as in each of the 72 counties. This report seeks to heighten awareness and provide critical information to communities so they can successfully initiate and support efforts to prevent sexual violence. The following data is included in the report: prevalence; reports to advocacy, medical (state-level only) and law enforcement; and convictions.



        The Osnium WS database is used throughout Wisconsin to track statistical data, which allows advocates to set goals, plan progress, and report on outcomes in prevention work.

        For questions on Osnium, please contact End Domestic Abuse Wisconsin at technology@endabusewi.org.


        Other Wisconsin Data

        • The WI Office of Justice Assistance (OJA) released an annual sexual assault report through 2010 which can be accessed on the Wisconsin Department of Justice page for Justice Statistics Documents (scroll down for sexual assault reports 2006-2010)



        NISVS – National Intimate Partner and Sexual Violence Survey 

        In December, 2011, the Centers for Disease Control and Prevention (CDC) released the 2010 Report from the National Intimate Partner and Sexual Violence Survey (NISVS). The report provides insight into the prevalence and characteristics of sexual violence, stalking, and intimate partner violence across the county, and in Wisconsin. The survey shows that more than 1 in 3 women and more than 1 in 4 men have experienced rape, physical violence, and/or stalking by an intimate partner in their lifetime.

        To access all NISVS information and reports please visit the NISVS page of the CDC website.
