In a recent study of a population of 41 deaf sex offenders incarcerated
by the state of Texas, the rate of sexual offending by deaf offenders
was 4 times the rate of sexual offending by hearing offenders with 30%
recidivism in the population. Sexual offending by deaf adults was
discussed in relation to the sexual abuse of deaf children. Sixty-two
percent of deaf sex offenders were functionally illiterate, a literacy
rate considerably below the average for deaf adults who remained in
school until age 18 or above. However, the performance IQs of deaf sex
offenders were comparable to those of the overall prison population.
