Nationally, the situation was similar. In 1955, state hospitals housed 560,000 patients, proportionately equivalent to 1.5 million today. Now, fewer than 40,000 inpatient psychiatric beds remain in the United States, but 550,000 people with mental illness are housed in jails and prisons, with another 900,000 in community control, said Leifman, who serves on the board of the American Psychiatric Foundation.
