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.

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 U.S. 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. From 1979 to 2013, the Census Bureau was the NPS data collection agent. In 2014, the collection was competitively bid in conjunction with the National Corrections Reporting Program (NCRP), since many of the respondents for NPS and NCRP are the same. The contract was awarded to Abt Associates, Inc. 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.

This statistic shows the share of the United States prison population that was Black in 2014, by state and the length of time inmates have served. In 2014, 58.7 percent of the prison population in Alabama was Black. For those inmates who had served 10 years or more, that figure rose to 67 percent.

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.

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.

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.

The Annual Survey of Jails (ASJ) is the only data collection effort that provides an annual source of data on local jails and jail inmates. Data on the size of the jail population and selected inmate characteristics are obtained every five to six years from the Census of Jails. In each of the years between the complete censuses, a sample survey of jails is conducted to estimate baseline characteristics of the nation's jails and inmates housed in these jails. The 2023 Annual Survey of Jails is the 35th such survey in a series begun in 1982. The ASJ supplies data on characteristics of jails such as admissions and releases, growth in the number of jail facilities, changes in their rated capacities and level of occupancy, growth in the population supervised in the community, changes in methods of community supervision, and crowding issues. The ASJ also provides information on changes in the demographics of the jail population, supervision status of persons held, and a count of non-U.S. citizens in custody. The data presented in this study were collected in the Annual Survey of Jails, 2023. These data are used to track growth in the number of jails and the capacities nationally, changes in the demographics of the jail population and supervision status of persons held, the prevalence of crowding issues, and a count of non-U.S. citizens within the jail population. The data are intended for a variety of users, including Federal and State agencies, local officials in conjunction with jail administrators, researchers, planners, and the public. The reference date for the survey is June 30, 2023.

As of 2021, **** percent of California's prison population were non-U.S. citizens, the highest share of any state in that year. Massachusetts, Nevada, New Jersey, and Arizona rounded out the top five states with the highest share of non-U.S. citizens in prison in that year.

Investigator(s): Bureau of Justice Statistics The National Jail Census was conducted by the U.S. Census Bureau for the Bureau of Justice Statistics. Excluded from the census were federal- or state-administered facilities, including the combined jail-prison systems in Alaska, Connecticut, Delaware, Hawaii, Rhode Island, and Vermont. Data include jail population by reason being held, age (juvenile or adult) and sex, maximum sentence that can be served in the facility, available services, type of security available, facility capacity, age, construction and renovation of the facility, employment, and operating expenditures.Years Produced: Every 5 years

The Central American nation with the highest prison population rate was El Salvador, with over 1,000 prisoners per 100,000 inhabitants, followed by Panama with 522 prisoners. The lowest prison population rate of the region was found in Guatemala, with 123 prisoners per 100,000 people.

Private Prison Service Market Outlook

The global private prison service market size was valued at approximately USD 8 billion in 2023 and is forecasted to reach USD 12.5 billion by 2032, expanding at a compound annual growth rate (CAGR) of around 4.5% during the forecast period. The growth of this market is driven by several factors, including increasing prison populations, government policies favoring privatization, and a focus on cost-efficiency and specialized services provided by private entities.

One of the primary growth factors of the private prison service market is the escalating prison population globally. Over the years, many countries have experienced a steady rise in incarceration rates due to stricter law enforcement policies and an increase in crime rates. This surge has led to overcrowded public prison facilities, prompting governments to seek alternatives to manage the burgeoning inmate numbers. Private prisons have emerged as a viable solution to this issue, providing additional capacity and thus driving market demand.

Another significant factor contributing to the growth of the private prison service market is the cost-efficiency and specialized services offered by private operators. Governments are increasingly outsourcing prison management to private entities to reduce operational costs and improve service quality. Private prisons often employ advanced technologies and management practices that lead to better resource utilization, enhanced security measures, and improved inmate rehabilitation programs. These factors make private prisons an attractive option for governments looking to manage prisons more effectively.

The increasing focus on rehabilitation and reintegration of inmates is also bolstering the private prison service market. Unlike traditional public prisons, many private facilities emphasize rehabilitation and education programs aimed at reducing recidivism rates. Private prison operators often provide comprehensive healthcare, vocational training, and educational programs tailored to the needs of inmates. These initiatives not only help in the personal development of inmates but also contribute to a safer society, which, in turn, drives the demand for private prison services.

From a regional perspective, North America holds the largest share in the global private prison service market, primarily driven by the United States, which has one of the highest incarceration rates in the world. Government policies favoring privatization and the presence of major private prison operators further strengthen the market in this region. However, other regions such as Asia Pacific and Europe are also showing significant potential due to increasing crime rates and shifting governmental policies towards privatization.

Service Type Analysis

The private prison service market is segmented by service type into security, rehabilitation, healthcare, education, and others. The security segment holds the largest market share due to its critical role in maintaining order and safety within prison facilities. Private prison operators invest heavily in advanced security technologies such as surveillance systems, biometric access controls, and perimeter security solutions. These investments ensure a secure environment for both inmates and staff, thereby making security services a pivotal component of the private prison market.

The rehabilitation segment is gaining traction as governments and private operators recognize the importance of reducing recidivism rates. Rehabilitation services include a range of programs such as behavioral therapy, substance abuse treatment, and vocational training designed to help inmates reintegrate into society. With growing awareness about the social and economic benefits of rehabilitation, this segment is expected to see substantial growth in the coming years.

Healthcare services are another critical component of private prison services. Inmates often have complex health needs that require specialized medical care. Private prison operators provide comprehensive healthcare services, including primary care, mental health services, and emergency medical treatment. The healthcare segment is expected to grow significantly due to the increasing prevalence of chronic conditions and mental health issues among the incarcerated population.

Educational services are also an essential part of the private prison service market. These services aim to equip inmates with the knowledge and skills needed to secure employment upon release. Educational programs range

Correctional facilities have suffered from a mixture of policy changes at the federal and local levels, coupled with broader support for rehabilitative solutions to the broader issue of crime. The implementation of a ban on private prison contract renewals with the DOJ in 2021 cut off a considerable revenue stream across BOP and USMS clientele. While the order was reversed in January 2025, facilities were forced to pivot to alternative revenue streams, namely community centers and rehabilitative service provision. Demand is uniquely separate from the broader economic climate, since revenue growth is primarily influenced by crime and incarceration rates. Falling approval of for-profit prisons also influenced statewide restrictions on private correctional facilities. Revenue fell at a CAGR of 3.6% to an estimated $9.0 billion, including an estimated 3.5% decline in 2025 alone, as profit reached an estimated 12.4%. Decreasing national crime and incarceration rates have been the primary contributing factors influencing revenue. A sharp 7.6% collapse in the national incarceration rate over the past five years was influenced by a conscious effort by the US government to reduce prison overcrowding. Since private correctional facilities charge fixed, per-diem rates based on occupancy, a reduction in the inmate population not only lowers demand for facility, but also raises fixed costs that eat into their profit margin. However, stricter immigration enforcement, caused agencies such as ICE to contract correctional facilities to provide detention and processing centers for new arrivals. In February 2025, major company GEO Group signed off on a contract with ICE for a new processing facility in Newark, New Jersey, providing a crucial revenue stream that offset larger losses. Moving forward, correctional facilities face an uncertain future. Continued slippage in public opinion regarding for-profit prison systems will force facilities to invest capital in rehabilitative services aimed at reentry and reduction of recidivism. Reputational problems stemming from reports of inadequate medical care, excessive use of solitary confinement and unsanitary conditions may lead to financial penalties or full-on closures. A continued retreat in national incarceration and crime rates will continue shrinking the potential marketplace for correctional facilities. Revenue is expected to sink at a CAGR of 3.6% to an estimated $7.5 billion over the next five years.

This statistic shows the percentage of prison population in the United States in 2014, by state and the length of time inmates have served. In 2014, ***** percent of inmates in Californian prisons had served 5 to 10 years.

The Latin America and Caribbean nation with the highest prison population rate in 2024 was El Salvador, with 1.086 prisoners per 100,000 inhabitants, the only country to achieve four digits, followed by Cuba with 794 prisoners. Guatemala and Haiti Jamaica had the lowest prison population rates, 123 and 63 per 100,000 inhabitants, respectively.

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.

To reduce respondent burden for the 2019 collection, the Census of Jails was combined with the Deaths in Custody Reporting Program (DCRP). The census provides the sampling frame for the nationwide Survey of Inmates in Local Jails (SILJ) and the Annual Survey of Jails (ASJ). Previous jail enumerations were conducted in 1970 (ICPSR 7641), 1972 (ICPSR 7638), 1978 (ICPSR 7737), 1983 (ICPSR 8203), 1988 (ICPSR 9256), 1993 (ICPSR 6648), 1999 (ICPSR 3318), 2005 (ICPSR 20367), 2006 (ICPSR 26602), and 2013 (ICPSR 36128). The RTI International collected the data for the Bureau of Justice Statistics in 2013 and 2019. The United States Census Bureau was the collection agent from 1970-2006. The 2019 Census of Jails gathered data from all jail detention facilities holding inmates beyond arraignment, a period normally exceeding 72 hours. Jail facilities were operated by cities and counties, by private entities under contract to correctional authorities, and by the Federal Bureau of Prisons (BOP). Excluded from the census were physically separate temporary holding facilities such as drunk tanks and police lockups that do not hold persons after being formally charged in court. Also excluded were state-operated facilities in Connecticut, Delaware, Hawaii, Rhode Island, Vermont, and Alaska, which have combined jail-prison systems. Fifteen independently operated jails in Alaska were included in the Census. The 2019 census collected information on the number of confined inmates, number of persons supervised outside jail, number of inmates participating in weekend programs, number of confined non-U.S. citizens, number of inmates by sex and adult or juvenile status, number of juveniles held as adults, number of inmates who were parole or probation violators, number of inmates by conviction status, number of inmates by felony or misdemeanor status, number of inmates held by race or Hispanic origin, number of inmates held for other jurisdictions or authorities, average daily population, rated capacity, admissions and releases, number of staff employed by local jails, facility functions, and number of jails under court orders and consent decrees. The 2019 census also included a module to collect data on the effects of the opioid epidemic on local jails and jail responses to the epidemic. Items included: Jail practices on opioid use disorder testing, screening, and treatment. Number of local jail admissions screened during June 2019. Number of positive screens. Number of admissions treated for opioid use disorder. Number of jail inmates treated for opioid withdrawal at midyear 2019.

The National Corrections Reporting Program (NCRP) compiles offender-level data on admissions and releases from state and federal prisons and post-confinement community supervision. The data are used to monitor the nation's correctional population and address specific policy questions related to recidivism, prisoner reentry, and trends in demographic characteristics of the incarcerated and community supervision populations. The Bureau of Justice Statistics (BJS) has administered the NCRP since 1983. The United States Bureau of the Census served as data collection agent for BJS until October 2010, when Abt Associates assumed this position. From 2000 to 2009, NCRP data were archived each year in four, year-specific files that corresponded to the four files that states were asked to submit to the Census Bureau. The four files are: Prison Admissions (Part A), Prison Releases (Part B), Parole Exits (Part C), and Prison Custody (Part D). For example, the 2009 NCRP archive consists of prison admissions occurring in 2009, prison releases occurring in 2009, parole exits occurring in 2009, and prisoners in custody on December 31, 2009. Starting in 2011, NCRP data will be archived in a single, multi-year Term Record file. A Term Record represents a single period of incarceration for an individual offender. Each year, the archived Term Record file will be replaced by a new Term Record file that incorporates new NCRP data collected and processed during the previous year, as well as updates to previously collected data. The Term Records were created from the Prison Admissions (Part A), Prison Releases (Part B), and Prison Custody (Part D) records submitted by states since 2000. With a few lines of computing code (included with the archive), an analyst can create a prison admission, release, or custody file from the Term Record file. In addition to the Term Record file, two additional files are being archived: (1) Prison Admissions (Part A), Prison Releases (Part B), and Prison Custody (Part D) records that were not used in building the Term Record file and (2) Part C (Parole Exit) records collected from January 1, 2011 to October 31, 2012.
