We have added another entry to the Bibliography:
Cortoni, F., Babchishin, K. M., & Rat, C. (2016). The Proportion of Sexual Offenders Who Are Female Is Higher Than Thought: A Meta-Analysis. Criminal Justice and Behavior
Women commit sexual offenses, but the proportion of sexual offenders who are female is subject to debates. Based on 17 samples from 12 countries, the current meta-analysis found that a small proportion of sexual offenses reported to police are committed by females (fixed-effect meta-analytical average = 2.2%). In contrast, victimization surveys indicated prevalence rates of female sexual offenders that were six times higher than official data (fixed-effect meta-analytical average = 11.6%). Female sexual offenders are more common among juvenile offenders than adult offenders, with approximately 2 percentage points more female juvenile sex offenders than female adult sex offenders. We also found that males were much more likely to self-report being victimized by female sex offenders compared with females (40% vs. 4%). The current study provides a robust estimate of the prevalence of female sexual offending, using a large sample of sexual offenses across diverse countries.
I am pleased to see that, especially from this researcher, some time is being put into looking at the numbers. Even so I suspect that the numbers are higher than even this study states. If you look at the numbers when it comes to female sex offenders and children the numbers go much higher.
