Prison in the United States

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 in 2014 had a total prison population of 735 out of a population of around 92,000). In 2013 in the US, there were 698 people incarcerated per 100,000 population. This is the U.S. incarceration rate for adults or people tried as adults.

According to the US Bureau of Justice Statistics (BJS), 2,220,300 adults were incarcerated in US federal and state prisons, and county jails in 2013 – about 0.91% of adults (1 in 110) in the U.S. resident population. Additionally, 4,751,400 adults in 2013 (1 in 51) were on probation or on parole. In total, 6,899,000 adults were under correctional supervision (probation, parole, jail, or prison) in 2013 – about 2.8% of adults (1 in 35) in the U.S. resident population. In 2014, the total number of persons in the adult correctional systems had fallen to 6,851,000 persons, approximately 52,200 fewer offenders than at the year end of 2013 as reported by the BJS. About 1 in 36 adults (or 2.8% of adults in the US) was under some form of correctional supervision – the lowest rate since 1996. On average the correctional population has declined by 1.0% since 2007; while this continued to stay true in 2014 the number of incarcerated adults slightly increased in 2014.

In addition, there were 54,148 juveniles in juvenile detention in 2013.

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 2016^[update]. 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.
