As of December 2022, there was a total of 139,631 prisoners in the state of Texas, the most out of any state. California, Florida, Georgia, and Ohio rounded out the top five states with the most prisoners in the United States.

The National Prisoner Statistics (NPS) data collection began in 1926 in response to a congressional mandate to gather information on persons incarcerated in state and federal prisons. Originally under the auspices of the United States Census Bureau, the collection moved to the Bureau of Prisons in 1950, and then in 1971 to the National Criminal Justice Information and Statistics Service, the precursor to the Bureau of Justice Statistics (BJS) which was established in 1979. Since 1979, the Census Bureau has been the NPS data collection agent. The NPS is administered to 51 respondents. Before 2001, the District of Columbia was also a respondent, but responsibility for housing the District of Columbia's sentenced prisoners was transferred to the federal Bureau of Prisons, and by yearend 2001 the District of Columbia no longer operated a prison system. The NPS provides an enumeration of persons in state and federal prisons and collects data on key characteristics of the nation's prison population. NPS has been adapted over time to keep pace with the changing information needs of the public, researchers, and federal, state, and local governments.

Private prisons, also referred to as for-profit prisons, have become a dominant sector of society in the United States and are now implemented in many states around the country. As of 2022, the state of Florida had the highest number of prisoners held in private prisons in the United States, with a total of ****** prisoners, followed by Texas, Arizona, and Georgia, and Tennessee. ** states did not have any prisoners held in private prisoners in that year. Private prisons in the U.S. The United States is home to the highest prison population per capita of all OECD countries, resulting in a consistent overcrowding of prisons which has negatively affected the criminal justice system for decades. The privatization of prison facilities was initially proposed as a solution to a lack of funding and an increasing demand for more jail space, leading to around *** percent of the U.S. prison population currently behind bars in private prisons. In 2021, ****** prisoners were held in in-state private prison facilities in the United States, compared to ****** prisoners held in out-of-state private prisons. Arguments on private prisons Advocates of private prisons proposed that privatization could lead to cost reductions, suggesting that allowing the private industry to operate prison facilities would save taxpayers money. However, the increasing reliance on private prison facilities has been criticized politically in the U.S. for catering to profit-seeking corporations as well as for the tendency to hold people in immigrant detention in these privately run facilities. In 2021, the highest share of revenue reported by the two largest for-profit prison companies in the U.S. was from U.S. Immigration and Customs Enforcement. In addition, Republican Senator Marco Rubio from Florida, who is well-known for his positive stance on strengthening border security, was also found to receive the most money from the private prison industry than any other federal politician in the 2022 election cycle.

As of February 2025, El Salvador had the highest prisoner rate worldwide, with over 1,600 prisoners per 100,000 of the national population. Cuba, Rwanda, Turkmenistan, and the United States, rounded out the top five countries with the highest rate of incarceration. Homicides in El Salvador Interestingly, El Salvador, which long had the highest global homicide rates, has dropped out of the top 20 after a high number of gang members have been incarcerated. A high number of the countries with the highest homicide rate are located in Latin America. Prisoners in the United StatesThe United States is home to the largest number of prisoners worldwide. More than 1.8 million people were incarcerated in the U.S. at the beginning of 2025. In China, the estimated prison population totaled 1.69 million people that year. Other nations had far fewer prisoners. The largest share of the U.S. prisoners in federal correctional facilities were of African-American origin. As of 2020, there were 345,500 black, non-Hispanic prisoners, compared to 327,300 white, non-Hispanic inmates. The U.S. states with the largest number of prisoners in 2022 were Texas, California, and Florida. Over 160,000 prisoners in state facilities were sentenced for rape or sexual assault, which was the most common cause of imprisonment. The second most common was murder, followed by aggravated or simple assault.

Investigator(s): Bureau of Justice Statistics Conducted by the Bureau of Justice Statistics, this survey is part of a series of data gathering efforts undertaken to assist policymakers in assessing and remedying deficiencies in the nation's correctional institutions. Its primary objective is to produce national statistics of the state and sentenced federal prison populations across a variety of domains. The survey gathered information on demographic, socioeconomic, and criminal history characteristics of prisoners. Also obtained were details of prisoner’ military service, current offense and sentence, incident characteristics, and firearm possession and sources. Other information includes age at time of interview, ethnicity, education, lifetime drug use and alcohol use and treatment, mental and physical health and treatment, and pre-arrest employment and income. Data on characteristics of victims, prison programs and services, and rule violations are provided as well. With the 2016 administration, the survey was renamed the Survey of Prison Inmates. NACJD has prepared a resource guide for the Survey of Prison Inmates Series.

Investigator(s): United States. Bureau of Justice Statistics Produces annual national- and state-level data on the number of prisoners in state and federal prison facilities. Aggregate data are collected on race and sex of prison inmates, inmates held in private facilities and local jails, system capacity, noncitizens, and persons age 17 or younger. Findings are released in the Prisoners series and the Corrections Statistical Analysis Tool (CSAT) - Prisoners. Data are from the 50 states departments of correction, the Federal Bureau of Prisons, and until 2001, from the District of Columbia (after 2001, felons sentenced under the District of Columbia criminal code were housed in federal facilities).

There were about 87,784 female prisoners under the jurisdiction of state or federal correctional authorities in the United States as of December 2022. This is an increase from the previous year, when there were 83,651 female prisoners in the country.

Overview

The Marshall Project, the nonprofit investigative newsroom dedicated to the U.S. criminal justice system, has partnered with The Associated Press to compile data on the prevalence of COVID-19 infection in prisons across the country. The Associated Press is sharing this data as the most comprehensive current national source of COVID-19 outbreaks in state and federal prisons.

Lawyers, criminal justice reform advocates and families of the incarcerated have worried about what was happening in prisons across the nation as coronavirus began to take hold in the communities outside. Data collected by The Marshall Project and AP shows that hundreds of thousands of prisoners, workers, correctional officers and staff have caught the illness as prisons became the center of some of the country’s largest outbreaks. And thousands of people — most of them incarcerated — have died.

In December, as COVID-19 cases spiked across the U.S., the news organizations also shared cumulative rates of infection among prison populations, to better gauge the total effects of the pandemic on prison populations. The analysis found that by mid-December, one in five state and federal prisoners in the United States had tested positive for the coronavirus -- a rate more than four times higher than the general population.

This data, which is updated weekly, is an effort to track how those people have been affected and where the crisis has hit the hardest.

Methodology and Caveats

The data tracks the number of COVID-19 tests administered to people incarcerated in all state and federal prisons, as well as the staff in those facilities. It is collected on a weekly basis by Marshall Project and AP reporters who contact each prison agency directly and verify published figures with officials.

Each week, the reporters ask every prison agency for the total number of coronavirus tests administered to its staff members and prisoners, the cumulative number who tested positive among staff and prisoners, and the numbers of deaths for each group.

The time series data is aggregated to the system level; there is one record for each prison agency on each date of collection. Not all departments could provide data for the exact date requested, and the data indicates the date for the figures.

To estimate the rate of infection among prisoners, we collected population data for each prison system before the pandemic, roughly in mid-March, in April, June, July, August, September and October. Beginning the week of July 28, we updated all prisoner population numbers, reflecting the number of incarcerated adults in state or federal prisons. Prior to that, population figures may have included additional populations, such as prisoners housed in other facilities, which were not captured in our COVID-19 data. In states with unified prison and jail systems, we include both detainees awaiting trial and sentenced prisoners.

To estimate the rate of infection among prison employees, we collected staffing numbers for each system. Where current data was not publicly available, we acquired other numbers through our reporting, including calling agencies or from state budget documents. In six states, we were unable to find recent staffing figures: Alaska, Hawaii, Kentucky, Maryland, Montana, Utah.

To calculate the cumulative COVID-19 impact on prisoner and prison worker populations, we aggregated prisoner and staff COVID case and death data up through Dec. 15. Because population snapshots do not account for movement in and out of prisons since March, and because many systems have significantly slowed the number of new people being sent to prison, it’s difficult to estimate the total number of people who have been held in a state system since March. To be conservative, we calculated our rates of infection using the largest prisoner population snapshots we had during this time period.

As with all COVID-19 data, our understanding of the spread and impact of the virus is limited by the availability of testing. Epidemiology and public health experts say that aside from a few states that have recently begun aggressively testing in prisons, it is likely that there are more cases of COVID-19 circulating undetected in facilities. Sixteen prison systems, including the Federal Bureau of Prisons, would not release information about how many prisoners they are testing.

Corrections departments in Indiana, Kansas, Montana, North Dakota and Wisconsin report coronavirus testing and case data for juvenile facilities; West Virginia reports figures for juvenile facilities and jails. For consistency of comparison with other state prison systems, we removed those facilities from our data that had been included prior to July 28. For these states we have also removed staff data. Similarly, Pennsylvania’s coronavirus data includes testing and cases for those who have been released on parole. We removed these tests and cases for prisoners from the data prior to July 28. The staff cases remain.

About the Data

There are four tables in this data:

• covid_prison_cases.csv contains weekly time series data on tests, infections and deaths in prisons. The first dates in the table are on March 26. Any questions that a prison agency could not or would not answer are left blank.

• prison_populations.csv contains snapshots of the population of people incarcerated in each of these prison systems for whom data on COVID testing and cases are available. This varies by state and may not always be the entire number of people incarcerated in each system. In some states, it may include other populations, such as those on parole or held in state-run jails. This data is primarily for use in calculating rates of testing and infection, and we would not recommend using these numbers to compare the change in how many people are being held in each prison system.

• staff_populations.csv contains a one-time, recent snapshot of the headcount of workers for each prison agency, collected as close to April 15 as possible.

• covid_prison_rates.csv contains the rates of cases and deaths for prisoners. There is one row for every state and federal prison system and an additional row with the National totals.

This data collection supplies annual data on the size of the prison population and the size of the general population in the United States for the period 1925 to 1986. These yearend counts include tabulations for prisons in each of the 50 states and the District of Columbia, as well as the federal prisons, and are intended to provide a measure of the overall size of the prison population. The figures were provided from a voluntary reporting program in which each state, the District of Columbia, and the Federal Bureau of Prisons reported summary statistics as part of the statistical information on prison populations in the United States.

Around 1.23 million people were imprisoned in the United States in 2022. This is a slight increase from the previous year, when 1.2 million people were in prison.

At the beginning of 2025, the United States had the highest number of incarcerated individuals worldwide, with around 1.8 million people in prison. China followed with around 100,000 fewer prisoners. Brazil followed in third. The incarceration problem in the U.S. The United States has an incredibly high number of incarcerated individuals. Therefore, the incarceration problem has become a widely contested issue, because it impacts disadvantaged people and minorities the most. Additionally, the prison system has become capitalized by outside corporations that fund prisons, but there is still a high cost to taxpayers. Furthermore, there has been an increase in the amount of private prisons that have been created. For-profit prison companies have come under scrutiny because of their lack of satisfactory staff and widespread lobbying. Violent offenses are the most common type of offense among prisoners in the U.S. Incarceration rates worldwide El Salvador had the highest rate of incarceration worldwide, at 1,659 prisoners per 100,000 residents as of February 2025. Cuba followed in second with 794 prisoners per 100,000 inhabitants. The incarceration rate is a better measure to use when comparing countries than the total prison populations, which will naturally have the most populous countries topping the list.

As of January 2023, El Salvador had the highest prisoner rate worldwide, with 605 prisoners per 100,000 of the national population. Rwanda, Turkmenistan, American Samoa, and Cuba rounded out the top five countries with the highest rate of incarceration.

Homicides in El Salvador

El Salvador is not only the country with the highest prison rate worldwide, but also the country with the highest murder rate, reaching over 50 per 100,000 inhabitants in 2022. A high number of the countries with the highest homicide rate are located in Latin America.

Prisoners in the United States

The United States is home to the second largest number of prisoners worldwide, only beaten by China. Roughly 1.68 million people were incarcerated in the U.S. in 2023. In China, the estimated prison population totaled to 1.69 million people that year. Other nations had far fewer prisoners.

The largest share of the U.S. prisoners in federal correctional facilities were of African-American origin. As of 2020, there were 345,500 black, non-Hispanic prisoners, compared to 327,300 white, non-hispanic inmates. The U.S. states with the largest number of prisoners in 2021 were Texas, California and Florida.

Over 160,000 prisoners in state facilities were sentenced for rape or sexual assault, which was the most common cause of imprisonment. Second most common were murder, followed by aggravated or simple assault.

The 2019 Census of State and Federal Adult Correctional Facilities (CCF) was the ninth enumeration of state institutions and the sixth enumeration of federal institutions sponsored by the Bureau of Justice Statistics and its predecessors. Earlier censuses were completed in 1979 (ICPSR 7852), 1984 (ICPSR 8444), 1990 (ICPSR 9908), 1995 (ICPSR 6953), 2000 (ICPSR 4021), 2005 (ICPSR 24642), and 2012 (ICPSR 37294). The 2019 CCF consisted of two data collection instruments - one for confinement facilities and one for community-based facilities. For each facility, information was provided on facility operator; sex of prisoners authorized to be housed by facility; facility functions; percentage of prisoners authorized to leave the facility; one-day counts of prisoners by sex, race/ethnicity, special populations, and holding authority; number of walkaways occurring over a one-year period; and educational and other special programs offered to prisoners. Additional information was collected from confinement facilities, including physical security level; housing for special populations; capacity; court orders for specific conditions; one-day count of correctional staff by payroll status and sex; one-day count of security staff by sex and race/ethnicity; assaults and incidents caused by prisoners; number of escapes occurring over a one-year period; and work assignments available to prisoners. Late in the data collection to avoid complete nonresponse from facilities, BJS offered the option of providing critical data elements from the two data collection instruments. These elements included facility operator; sex of prisoners authorized to be housed by facility; facility functions; percentage of prisoners authorized to leave the facility; one-day counts of prisoners by sex, and holding authority. Physical security level was an additional critical data element for confinement facilities. The census counted prisoners held in the facilities, a custody count. Some prisoners who are held in the custody of one jurisdiction may be under the authority of a different jurisdiction. The custody count is distinct from a count of prisoners under a correctional authority's jurisdiction, which includes all prisoners over whom a correctional authority exercises control, regardless of where the prisoner is housed. A jurisdictional count is more inclusive than a prison custody count and includes state and federal prisoners housed in local jails or other non-correctional facilities.

This data collection includes tabulations of annual adult admissions to federal and state correctional institutions by gender for the years 1926 through 1987. The two data files have identical structures: Part 1 includes information on male admissions, and Part 2 includes information on female admissions. The 3,348 cases in each part include one case for each of the 62 years of the collection for each of the following 54 categories: the 50 states, the District of Columbia, federal institutional totals, state cumulative totals, and United States totals (the sum of the federal and state cumulative totals). The figures were drawn from a voluntary reporting program in which each state, the District of Columbia, and the Federal Bureau of Prisons reported summary and detailed statistics, as part of the National Prisoner Statistics reporting series. Each file also includes individual state and United States general population figures.

Investigator(s): Bureau of Justice Statistics This series of studies contains a descriptive analysis of federal and state-operated adult confinement and correctional facilities nationwide. The census included prisons, penitentiaries, and correctional facilities; boot camps; community corrections; prison farms; reception, diagnostic, and classification centers; road camps; forestry and conservation camps; youthful offender facilities (except in California); vocational training facilities; prison hospitals; and correctional drug and alcohol treatment facilities. Variables include physical security, age of facilities, functions of facilities, programs, inmate work assignments, staff employment, facilities under court order/consent decree for conditions of confinement, capital and operating expenditures, custody level of residents/inmates, one-day and average daily population counts, race/ethnicity of inmates, inmate deaths, special inmate counts, and assaults and incidents by inmates. The institution is the unit of analysis. The Census of State and Federal Adult Correctional Facilities is produced every 5 years.

Introduction

Prison Statistics: Prisons serve as critical institutions within global justice systems, reflecting societal approaches to punishment, deterrence, and rehabilitation. As of 2024, approximately 11.5 million individuals are incarcerated worldwide, with about 10.8 million men and 700,000 women. This represents a 5.5% increase since 2012, indicating a persistent reliance on incarceration.

Incarceration rates vary significantly across regions. North America has the highest rate, with 489 prisoners per 100,000 people in 2022, down from 647 in 2012. In contrast, Southern Asia reported rates below 100 per 100,000 population. El Salvador leads globally with 1,086 prisoners per 100,000 people, followed by Cuba at 794 and Rwanda at 637.

The female prison population has surged by 57% since 2000, outpacing the 22% increase in the male prison population. This rise is often linked to factors such as poverty, discriminatory laws, and limited access to legal resources. Notably, one in three incarcerated individuals globally is held in pre-trial detention, highlighting concerns about legal processes and the presumption of innocence.

Understanding these demographics is essential for evaluating the effectiveness of incarceration as a tool for justice and rehabilitation. It also underscores the need for reforms that address systemic issues contributing to high incarceration rates. Let's explore some intriguing statistics about prisoners in the United States.

In 2022, about *** people per 100,000 inhabitants were imprisoned in the state of Mississippi, the most out of any state. The imprisonment rate stood at *** people per 100,000 inhabitants in the United States in that year.

The dataset contains year- and state-wise compiled data on the total number of undertrials and convicted prisoners (inmates), together with total prison capacity and occupancy ratio in the prisons of India

This data collection contains information gathered in a two-part survey that was designed to assess institutional conditions in state and federal prisons and in halfway houses. It was one of a series of data-gathering efforts undertaken during the 1970s to assist policymakers in assessing and overcoming deficiencies in the nation's correctional institutions. This particular survey was conducted in response to a mandate set forth in the Crime Control Act of 1976. Data were gathered via self-enumerated questionnaires that were mailed to the administrators of all 558 federal and state prisons and all 405 community-based prerelease facilities in existence in the United States in 1979. Part 1 contains the results of the survey of state and federal adult correctional systems, and Part 2 contains the results of the survey of community-based prerelease facilities. The two files contain similar variables designed to tap certain key aspects of confinement: (1) inmate (or resident) counts by sex and by security class, (2) age of facility and rated capacity, (3) spatial density, occupancy, and hours confined for each inmate's (or resident's) confinement quarters, (4) composition of inmate (or resident) population according to race, age, and offense type, (5) inmate (or resident) labor and earnings, (6) race, age, and sex characteristics of prison (or half-way house) staff, and (7) court orders by type of order and pending litigation. Other data (contained in both files) include case ID number, state ID number, name of facility, and operator of facility (e.g., federal, state, local, or private).
