Approximately 16% of all prison and jail inmates have a serious mental illness, and more than half have a clinical diagnosis, a treatment history, or symptoms of mental illness, according to research cited in Lifelines. Within 18 months of release, 64% of those with mental illnesses are rearrested—more than twice the rate of those without mental illnesses. Entitlements such as Medicaid and Medicare, veterans benefits, and Social Security income support enable individuals to obtain mental health care, housing, and other services. Without assistance, released inmates often wait months for benefits—a major factor in their high recidivism rate. However, only a third of inmates nationally receive benefits restoration planning.
