"The Federal Bureau of Prisons (BOP) is a United States federal law enforcement agency. A subdivision of the U.S. Department of Justice, the Bureau is responsible for the administration of the federal prison system. The system also handles prisoners who committed acts considered felonies under the District of Columbia's law. The Bureau was established in 1930 to provide more progressive and humane care for federal inmates, to professionalize the prison service, and to ensure consistent and centralized administration of the 11 federal prisons in operation at the time.
According to its official web site, the Bureau consists of more than 116 institutions, six regional offices, its headquarters office in Washington, D.C., two staff training centers, and 22 community corrections offices, and is responsible for the custody and care of approximately 210,000 federal offenders. Approximately 82 percent of these inmates are confined in Bureau-operated correctional facilities or detention centers. The remainder are confined through agreements with state and local governments or through contracts with privately operated community corrections centers, detention centers, prisons, and juvenile facilities."

"Incarceration in the United States of America is one of the main forms of punishment, rehabilitation, or both for the commission of felony and other offenses. The United States has the highest documented incarceration rate in the world. At year-end 2009, it was 743 adults incarcerated per 100,000 population.
According to the U.S. Bureau of Justice Statistics (BJS), 2,266,800 adults were incarcerated in U.S. federal and state prisons, and county jails at year-end 2011 – about 0.94% of adults in the U.S. resident population. Additionally, 4,814,200 adults at year-end 2011 were on probation or on parole. In total, 6,977,700 adults were under correctional supervision (probation, parole, jail, or prison) in 2011 – about 2.9% of adults in the U.S. resident population.
In addition, there were 70,792 juveniles in juvenile detention in 2010.
