This study examined the recidivism rates of female sexual offenders. A meta-analysis of 10 studies (2,490 offenders; average follow-up 6.5 years) showed that female sexual offenders have extremely low rates of sexual recidivism (less than 3%). The recidivism rates for violent (including sexual) offences and for any type of crime were predictably higher than the recidivism rates for sexual offences but still lower than the recidivism rates of male sexual offenders. These findings indicate the need for distinct policies and procedures for assessing and managing the risk of male and female sexual offenders. Risk assessment tools developed specifically for male sexual offenders would be expected to substantially overestimate the recidivism risk of female sexual offenders.
female sexual offenders, recidivism, meta-analysis
Although tremendous advances have been made in the understanding of the recidivism rates of adult male sexual offenders, similar knowledge is still extremely limited for female sexual offenders. Like men, women convicted of sexual offenses are subject to social control policies (e.g., Canadian Dangerous Offender Provisions, U.S. Sexually Violent Predator laws). Without an empirical basis for risk assessment, the

assessment of these women remains as problematic as the assessment of male sexual offenders was 20 years ago. Reliable estimates of the recidivism base rates of female sexual offenders would be a valuable aid to applied decision makers. Providing these estimates is the primary goal of this study.
Prevalence of Sexual Offending by Women
The prevalence rate of female sexual offending is difficult to ascertain. Some authors believe that sexual offending by females is relatively common but that its extent is unknown because of the lack of reporting or because these women tend to be diverted from the criminal justice system (Vandiver & Walker, 2002). Others suggest that sexual offending by women is likely to be underidentified because of societal and cultural stereotypes of female sexual behavior, including professional biases (Denov, 2003, 2004; Giguere & Bumby, 2007).
