Jails hold more of Virginia’s mentally ill population than state-run and private hospitals combined, according to a report released this week.

The study, prepared by the General Assembly’s Joint Legislative and Audit Review Commission, outlines a decades-long shift in the ratio of mentally ill inmates to patients. In 1936, there was one such person in a jail to every six in a state hospital. By 2005, that figure had almost turned upside down, with five mentally ill people in jails for every two in hospitals.
