" Rates of inmate-on-inmate sexual victimization among prison inmates were higher among females (6.9%) than males (1.7%), higher among whites (2.9%) or inmates of two or more races (4.0%) than among blacks (1.3%), higher among inmates with a college degree (2.7%) than among inmates who had not completed high school (1.9%), and lower among currently married inmates (1.4%) than among inmates who never married (2.1%) (table 7).
" Similar patterns of inmate-on-inmate sexual victimization were reported by jail inmates. Female jail inmates (3.6%), whites (2.0%), and inmates with a college degree (3.0%) reported higher rates of victimization than males (1.4%), blacks (1.1%), and inmates who had not completed high school (1.4%).
" Rates of inmate-on-inmate sexual victimization were unrelated to age among state and federal prisoners, except for slightly lower rates among inmates age 55 or older.
" Rates were lower among jail inmates in the oldest age categories (ages 35 to 44, 45 to 54, and 55 or older) than among jail inmates ages 20 to 24."
