The Federal Bureau of Prisons was established in 1930 to provide more progressive and humane care for federal inmates, to professionalize the prison service and ensure consistent and centralized administration of the 11 federal prisons that were operating in that year. It currently consists on just over 100 institutions throughout the Unites States, six regional offices, a central office, two staff training centers and 28 community corrections offices. The Federal Bureau of Prisons is responsible for the custody on nearly 185,000 federal inmates. Almost 85 percent are confined in bureau-operated correctional facilities or detention centers, including Washington, D.C. The Federal Bureau of Prisons employs more than 35,000 people who ensure the security of federal prisons and provide inmates with needed programs and services.
