Incarceration in the United States

Incarceration in the United States is one of the primary means of punishment for crime in the United States. In 2023, over five million people were under supervision by the criminal justice system, with nearly two million people incarcerated in state or federal prisons and local jails. The United States has the largest known prison population in the world, it has 5% of the world’s population, and 20% of the world’s incarcerated persons. China, with four times more inhabitants, has fewer persons in prison. Prison populations grew dramatically beginning in the 1970s, but began a decline around 2009, dropping 25% by year-end 2021.

Drug offenses account for the incarceration of about 1 in 5 people in U.S. prisons. Violent offenses account for over 3 in 5 people (62%) in state prisons. Property offenses account for the incarceration of about 1 in 7 people (14%) in state prisons.

The United States maintains a higher incarceration rate than most developed countries. According to the World Prison Brief on May 7, 2023, the United States has the sixth highest incarceration rate in the world, at 531 people per 100,000. Expenses related to prison, parole, and probation operations have an annual estimated cost of around $81 billion. Court costs, bail bond fees, and prison phone fees amounted to another $38 billion in costs annually.

Since reaching its peak level of imprisonment in 2009, the US has averaged a rate of decarceration of 2.3% per year. This figure includes the anomalous 14.1% drop in 2020 in response to the COVID-19 pandemic. There is significant variation among state prison population declines. Connecticut, New Jersey, and New York have reduced their prison populations by over 50% since reaching their peak levels. Twenty-five states have reduced their prison populations by 25% since reaching their peaks. The federal prison population downsized 27% relative to its peak in 2011.

Although debtor's prisons no longer exist in the United States, residents of some US states can still be incarcerated for debt as of 2016. The Vera Institute of Justice reported in 2015 that the majority of those incarcerated in local and county jails are there for minor violations and have been jailed for longer periods of time over the past 30 years because they are unable to pay court-imposed costs.
