"Among people in state and federal prisons in 2016, an estimated 40.4 percent reported a psychiatric disability, and 56.0 percent reported a nonpsychiatric disability (exhibit 1). Overall, an estimated 66 percent of incarcerated people were disabled. Exhibit 1 presents the distribution of specific types of disability and shows that bipolar, depressive, and anxiety disorders were especially common among psychiatric disabilities, as were cognitive disability, attention deficit hyperactivity disorder, and having been enrolled in “special education” among nonpsychiatric disabilities."
