Sex Offenses and Offenders
Draws on more than two dozen statistical datasets maintained by the Bureau of Justice Statistics and on data from the Uniform Crime Reporting (UCR) Program of the FBI to provide a comprehensive overview of current knowledge about the incidence and prevalence of violent victimization by sexual assault, the response of the criminal justice system to such crimes, and the characteristics of those who commit sexual assault or rape. Findings include the following:
Convicted rape and sexual assault offenders serving time in State prisons report that two-thirds of their victims were under the age of 18, and 58% of those–or nearly 4 in 10 imprisoned violent sex offenders – said their victims were aged 12 or younger.
In 90% of the rapes of children less than 12 years old, the child knew the offender, according to police-recorded incident data.
