About 1.85 million people were locked up in US prisons and jails at the end of 2023, the most recent year with comprehensive data from the Bureau of Justice Statistics.1Bureau of Justice Statistics. Correctional Populations in the United States, 2023 – Statistical Tables That total splits across roughly 1.1 million people in state prisons, about 153,500 in federal prisons, and about 664,200 in local jails. Add the roughly 3.8 million adults on probation or parole and the number of people under some form of correctional control climbs to about 5.6 million.2Bureau of Justice Statistics.

The Three Buckets Behind the 1.85 Million
The headline figure of 1,852,900 covers three kinds of facilities, and they operate very differently.
State prisons hold the largest share. About 1.1 million people were under state correctional authority at the end of 2023, almost all serving sentences longer than one year for felony convictions under state law.3Bureau of Justice Statistics. Prisoners in 2023 – Statistical Tables Each state runs its own department of corrections, which is why conditions, programming, and sentence length can vary so much from one state line to the next.
Federal prisons are a much smaller slice. The Federal Bureau of Prisons reported 153,535 inmates as of March 2026.4Federal Bureau of Prisons. Population Statistics The federal population has been drifting down, falling about 1% from 155,972 at the end of 2023 to 154,093 at the end of 2024.5Bureau of Justice Statistics. Federal Prisoner Statistics Collected Under the First Step Act, 2025 Because the federal system is small relative to the states, federal reforms like the First Step Act reach only a modest share of the overall incarcerated population.6Federal Bureau of Prisons. An Overview of the First Step Act
Local jails held 664,200 people at midyear 2023.7Bureau of Justice Statistics. Jail Inmates in 2023 – Statistical Tables Jails are run by cities and counties and house two very different groups: people who have been arrested and are awaiting the outcome of their case, and people serving short sentences, usually under a year. Turnover is high, with millions of admissions and releases every year. The distinction matters because the policy levers for jails and prisons are different. Jail numbers move with bail reform and pretrial diversion; prison numbers move with sentencing policy and parole decisions.
Who Isn’t Counted in That Number
The 1.85 million figure leaves out several populations that most people would consider incarcerated.
US Immigration and Customs Enforcement held over 68,000 people in immigration detention as of early 2026, a number that has grown sharply in recent years. About 29,300 youth were in juvenile residential placement facilities in 2023. Neither group shows up in the standard BJS incarceration count. The 3.8 million adults on probation or parole aren’t behind bars at all, but they are under correctional supervision and subject to re-incarceration for violations.2Bureau of Justice Statistics. Probation and Parole in the United States, 2023
How That Compares to the Rest of the World
The US incarceration rate sits around 540 per 100,000 residents, placing it among the top five nations worldwide. Western Europe averages about 86 per 100,000. Eastern Europe averages around 233. Northern America has the highest regional incarceration rate on the planet, and the United States drives that number almost entirely.
The gap isn’t explained by crime rates alone. US sentences tend to be much longer than those in peer countries, and the widespread use of pretrial detention fills local jails with people who haven’t been convicted of anything. Nations with similar wealth and similar crime levels simply don’t lock up anywhere near as many of their residents.
What People Are Serving Time For
The composition of the incarcerated population surprises many readers. In state prisons, where most prisoners are held, about 62% are serving time for violent offenses, including homicide, robbery, and assault. That share has risen from 46% in 1990. Drug offenses and property crimes make up smaller and shrinking slices of the state prison population.
The federal system looks different. Drug offenses, overwhelmingly trafficking and distribution rather than simple possession, account for roughly 43% of federal inmates. Property crimes like burglary and fraud make up only about 5%.8Federal Bureau of Prisons. Inmate Offenses Weapons and immigration offenses account for much of the rest. In fiscal year 2024, about one-quarter of federal cases involved an offense carrying a statutory mandatory minimum.9United States Sentencing Commission. Mandatory Minimum Penalties
Because the state system dwarfs the federal one, the overall picture of US incarceration is shaped mostly by violent crime convictions at the state level. A substantial share of prisoners will never leave: about 194,800 people were serving life sentences as of 2024, roughly 16% of everyone in prison, including about 56,200 serving life without the possibility of parole.
Who Is Incarcerated
The racial makeup of US prisons does not mirror the country’s population. Black Americans made up 33% of the sentenced prison population at the end of 2023 while representing about 13% of the US population. Hispanic individuals accounted for 23%, and white Americans made up 31%.3Bureau of Justice Statistics. Prisoners in 2023 – Statistical Tables
Measured by rate, the disparity sharpens. Black adults were imprisoned at about five times the rate of white adults in 2023: 1,218 per 100,000 Black adults compared to 231 per 100,000 white adults. American Indian and Alaska Native adults were imprisoned at 1,045 per 100,000, nearly as high.3Bureau of Justice Statistics. Prisoners in 2023 – Statistical Tables
Men make up roughly 93% of the federal prison population.10Federal Bureau of Prisons. Inmate Sex Across state prisons and jails combined, the share is around 90%. The female prison population has been climbing, growing between 2022 and 2023 in 41 states.3Bureau of Justice Statistics. Prisoners in 2023 – Statistical Tables
Most incarcerated people are between 25 and 44. In federal prisons, the 31-to-45 range alone accounts for about half of all inmates.11Federal Bureau of Prisons. Inmate Age The fastest-growing segment is older adults. The number of state prisoners aged 55 and over grew 400% between 1993 and 2013, pushed up by long sentences and truth-in-sentencing laws that keep people locked up into old age.12Bureau of Justice Statistics. Aging of the State Prison Population, 1993-2013
Regional Differences
Where someone lives in the United States shapes the odds of ending up behind bars. The South locks up people at far higher rates than any other region, and several southern states clear 500 per 100,000 residents. Mississippi leads the nation at 661 per 100,000, followed by Louisiana at 596, Arkansas at 574, and Oklahoma at 563. Northeastern states tend to fall well below the national average.
These gaps reflect policy as much as crime. Mandatory minimums, habitual offender laws, the availability of diversion programs, and prosecutorial charging practices all vary by state. Two states with similar crime rates can end up with very different incarceration rates, and the same offense that draws probation in one state can bring years of prison time in another.
Where the Numbers Come From
The Bureau of Justice Statistics, part of the Department of Justice, is the main federal agency tracking incarceration. Two programs do most of the work. The National Prisoner Statistics program collects annual data from all 50 state corrections departments, the Federal Bureau of Prisons, and US territories.13Bureau of Justice Statistics. National Prisoner Statistics The Annual Survey of Jails samples about 950 local facilities to produce national estimates for the jail population.14Bureau of Justice Statistics. Annual Survey of Jails
These figures come out with a lag, which is why the most recent full snapshot of the combined incarcerated population reflects the end of 2023. The BOP posts its own count in near real time, and individual states release data on their own schedules. That’s why totals vary slightly depending on the source and the date attached to them.
