Incarceration in the United States is one of the main forms of punishment, rehabilitation, or both for the commission of felony and other offenses. The United States has the largest prison population in the world, and the second-highest per-capita incarceration rate, behind Seychelles (which has a total prison population of 786 out of a population of 90,024). In 2012, it was 707 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. Although debtor’s prisons no longer exist in the United States, residents of some U.S. states can still be incarcerated for debt as of 2014. The Vera Institute of Justice reported in 2015 that jails throughout the United States have become warehouses for the poor, the mentally ill and those suffering from addiction as such individuals lack the financial means or mental capacity to post bail. According to a 2014 report by Human Rights Watch, “tough-on-crime” laws adopted since the 1980s have filled U.S. prisons with mostly nonviolent offenders. This policy failed to rehabilitate prisoners and many were worse on release than before incarceration. Rehabilitation programs for offenders can be more cost effective than prison. According to the Brennan Center for Justice, falling crime rates cannot be ascribed to mass incarceration.
