Research has shown that sex offenders are more likely to recidivate with a nonsexual offense than a sexual offense. In a study of 15 states’ inmates, of 9,691 sex offenders released from prison in 1994, 3.5 percent were reconvicted for a sex crime and about one-quarter (24 percent) were reconvicted for an offense of any kind during the followup period. However, researchers agree that these statistics may underestimate¬†the actual recidivism rates due to the difficulty of convicting defendants¬†in sex offense cases.
