In 2018, the CDC published the results of a 2015 scientific survey that found 13.5% of adult women in the U.S. have been the victims of acts that constitute forcible rape. The study identified cases of forcible rape by positive responses to questions about vaginal, oral, or anal sex acts done unwillingly because of physical force or threats of physical harm. These acts accord with the definition of rape under federal law. For more context and facts that debunk common misinformation about rape, see the second link below.
