In 2022, the CDC published the results of a scientific survey that found 16.3% of women in the U.S. say they 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. Those acts accord with the definition of rape under federal law. Over a lifetime, this figure is likely larger because: (1) the study didn’t account for the fact that some of the younger respondents will be victimized later in life. (2) the study’s definition of forcible rape doesn’t include surreptitious drugged rapes. (3) “victims who are involved in violent relationships or who have recently experienced severe forms of violence might be less likely to participate in surveys or might not be willing to disclose their experiences because of unresolved emotional trauma or concern for their safety, among other reasons.”
