Although a great deal of literature pertains to male sex offenders, it is not known whether these research findings are applicable to female sex offenders because little empirical research regarding female sex offenders exists. Currently, females make up approximately one percent to two percent of all sex offenders. This article includes a case review of the 40 registered female sex offenders in the state of Arkansas. The female sex offenders are compared to the registered male sex offenders in Arkansas. The majority of the female sex offenders were found to be Caucasian with an average age of 31 at the time of the first sex offense. Most of the offenders had a history of only one sex offense with no other criminal history. Most of the offenders were arrested for rape or first-degree sexual abuse. Females were slightly younger the male sex offenders at the time of arrest for their initial sex offense. Females were significantly more likely to be first-time offeders at the time of rest for their first sex offenders. The article concludes that female sex offenders differ slightly from males, indicating the need for the development of a new sex offender typology. © 2002, Sage Publications. All rights reserved.
