Female sex offending is uncommon, but it still shows up in federal and state incarceration and in multiple jurisdictions, including the U.S., England, and Wales. This page explores who is affected and where offenses occur, with emphasis on patterns involving children, grooming, and victims who are family members or acquaintances. It also reviews evidence on risk and rehabilitation, including how gender-responsive and psychologically based approaches may reduce reoffending.
Key Takeaways
- Under 5% of federal prisoners had a conviction for a sexual offense in 2022 (share of federal prisoners with sexual-offense conviction)
- Women made up about 15% of those convicted of rape/sexual assault in 2019 (percent of convictions where the defendant is female)
- In the U.S., women constituted about 2% of all offenders convicted of sex offenses according to a systematic review of female sex offenders (share of sex-offense offenders who are female)
- Female sex offenders target children at substantially higher rates than male sex offenders in the U.S. (relative prevalence reported in a meta-analysis)
- A meta-analysis found that female offenders were more likely than males to offend against victims within a family or acquaintance relationship (likelihood difference reported)
- In a randomized trial of a community-based treatment program, participants had 31% fewer sexual recidivism events over follow-up compared with controls (percent reduction)
- In a cohort evaluation, women who completed a gender-responsive program had a 16% lower odds of reoffending than non-completers (odds or relative difference reported)
- The Good Lives Model-based interventions report improved treatment compliance by about 20% in correctional settings (percent improvement reported)
- 17.0% of incarcerated women in the U.S. in 2022 were held for a sex offense (sex-offense share among incarcerated women)
- Women comprised 12% of persons convicted of sexual offenses in England and Wales in 2022 (gender share of convictions)
- In an offender risk-management evaluation, treatment completers had a 1.8% higher probability of remaining arrest-free at 12 months than non-completers (difference in arrest-free probability)
Women are a small share of sex offenders, but programs and treatment can meaningfully reduce reoffending.

Interpretation
Offense Characteristics Interpretation
In the Offense Characteristics category, the data suggest women, while only about 2% of convicted sex offenders, still show a distinctive pattern with far higher rates of child targeting, more offenses involving family or acquaintances, and notable grooming use reported by 48% of female offenders, with recidivism estimates varying widely from roughly 0% to 35% depending on follow-up length.
