" Black and Hispanic state prisoners were less likely than white state prisoners to report a hearing, cognitive, ambulatory, or independent-living disability.
" Black federal prisoners were less likely than white federal prisoners to report a hearing, vision, cognitive, ambulatory, or independent-living disability, and equally likely to report a self-care disability.
" More than half of state (57%) and federal (51%) prisoners ages 55 to 64 reported having a disability, and 7 in 10 state (70%) and federal (68%) prisoners age 65 or older reported a disability.
" State and federal prisoners (38%) were about two and a half times more likely to report a disability than adults in the U.S. general population (15%) (table 4).
" Twenty-five percent of state prisoners and 14% of federal prisoners reported having ever attended special education classes (table 5).
