"The reported use or threat of physical force to engage in sexual activity with staff was generally low among all prison and jail inmates (0.8%); however, at least 5% of the inmates in three state prisons and one high-rate jail facility reported they had been physically forced or threatened with force. (See appendix tables 3 and 7.) The Clements Unit (Texas) had the highest percentage of inmates reporting sexual victimization involving physical force or threat of force by staff (8.1%), followed by Denver Women’s Correctional Facility (Colorado) (7.3%), and Idaho Maximum Security Institution (6.0%). Wilson County Jail (Kansas) led all surveyed jails, with 5.6% of inmates reporting that staff used physical force or threat of force to have sex or sexual contact.
"While 0.8% of prison and jail inmates reported the use or threat of physical force, an estimated 1.4% of prison inmates and 1.2% of jail inmates reported being coerced by facility staff without any use or threat of force, including being pressured or made to feel they had to have sex or sexual contact. In 8 of the 24 facilities with high rates of staff sexual misconduct, at least 5% of the inmates reported such pressure by staff. Among state prisoners, the highest rates were reported by female inmates in the Denver Women’s Correctional Facility (Colorado) (8.8%) and by male inmates in the Clements Unit (Texas) (8.7%). Among jail inmates, the highest rates were reported by inmates in the Rose M. Singer Center (New York) (5.6%) and the Contra Costa County Martinez Detention Facility (California) (5.2%)."
