Federal, District of Columbia, and States' Future Prison and Correctional Institution Populations and Capacities

In response to a congressional request, GAO obtained information on the prison and correctional institution populations and capacities of the Federal prison system, the District of Columbia, and the 50 States for the period 1983 through 1990; compared their projections of future populations with their estimates of future correctional institution capacities; and examined the methods and models used by the Bureau of Prisons and District in their prison population projections.
