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.

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.

In 2023 Turkey had the highest incarceration rate among European countries, at 408 prisoners per 100,000 inhabitants, followed by Georgia, which had an incarceration of 256. The country with the lowest incarceration rate in this year was Liechtenstein, which had 15 people in prison for every 100,000 inhabitants. Germany had one of the lowest rates of 69 when compared with other major European countries such as France and England & Wales, which had rates of 106 and 136 respectively. The Russian Federation has in previous years been the country with the highest incarceration rate in the Council of Europe's data, however, as the country was removed as a member of the council in 2022 due to their invasion of Ukraine, data for Russia is no longer available.

With approximately *** million prisoners, China had by far the biggest prison population across the Asia-Pacific region in 2022. In contrast, less than ************ people were incarcerated in Brunei and Timor-Leste, respectively. Prison populations and total populationsThe varying size of prison populations throughout Asia-Pacific can be attributed to the size of the general populations across the region's countries and territories. With a population of over *** billion, China is the most populous country in the world. Despite the disparity in population size, Bhutan, which had one of the smallest prison populations in APAC in 2022, had a higher serious assault rate than other Asia-Pacific counties. Crime ratesApart from the general population size, there are other factors which can be taken into consideration, such as a diversity in justice systems. Therefore, a comparison of crime throughout the region can be challenging. Although China had a higher prison population, it had a lower intentional homicide rate compared to other Asia-Pacific countries and territories. New Zealand, Singapore, and Hong Kong have the lowest corruption index scores in the region, whereas countries including Bangladesh, Cambodia, and North Korea have recorded the highest scores.

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.

As of May 2025, the Republic of Congo recorded the world’s highest prison occupancy rate, operating at approximately 616.9 percent of its official capacity. Cambodia followed with an occupancy rate of 409.1 percent.

Hong Kong had the largest share of female prisoners as of April 2025, with over ** percent of its detainees being women. Macau had the second-highest rate at over ** percent. In the United States, *** percent of inmates were women.

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

In 2011, a historic Supreme Court decision mandated that the state of California substantially reduce its prison population to alleviate overcrowding, which was deemed so severe as to preclude the provision of adequate healthcare. To comply, California passed the Public Safety Realignment Act (Assembly Bill [AB] 109), representing the largest ever court-ordered reduction of a prison population in U.S. history. AB109 was successful in reducing the state prison population; however, although the policy was precipitated by inadequate healthcare in state prisons, no studies have examined its effects on prisoner health. As other states grapple with overcrowded prisons and look to California’s experience with this landmark policy, understanding how it may have impacted prisoner health is critical. We sought to evaluate the effects of AB109 on prison mortality and assess the extent to which policy-induced changes in the age distribution of prisoners may have contributed to these effects. To do so, we used prison mortality data from the Bureau of Justice Statistics and the California Deaths in Custody reporting program and prison population data from the National Corrections Reporting Program to examine changes in overall prison mortality, the age distribution of prisoners, and age-adjusted prison mortality in California relative to other states before and after the implementation of AB109. Following AB109, California prisons experienced an increase in overall mortality relative to other states that attenuated within three years. Over the same period, California experienced a greater upward shift in the age distribution of its prisoners relative to other states, suggesting that the state’s increase in overall mortality may have been driven by this change in age distribution. Indeed, when accounting for this differential change in age distribution, mortality among California prisoners exhibited a greater reduction relative to other states in the third year after implementation. As other states seek to reduce their prison populations to address overcrowding, assessments of California’s experience with AB109 should consider this potential improvement in age-adjusted mortality.

As of May 2025, Monaco had the largest share of foreign prisoners, with almost 90 percent of its detainees being foreigners. The United Arab Emirates was ranked second, with 87.5 percent of foreign prisoners.

Correctional System Market Outlook

The global correctional system market size was valued at approximately USD 5.8 billion in 2023 and is projected to reach USD 10.6 billion by 2032, growing at a compound annual growth rate (CAGR) of 6.9% from 2024 to 2032.

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.

The 1922 Prison System Enquiry Committee Report said that: 'In order to judge our Prison system rightly it is necessary to know what kind of people become prisoners... How many go to prison? For what length of sentence?' These questions persist, and are especially relevant for today's prison crisis. This project will assess nearly 100 years of historical data to explore, for the first time, how prison numbers were largely dictated by the repeat incarceration of recidivist's offenders with short sentences. It questions how the prison authorities attempted to manage increasing numbers of offenders by using early release schemes (licenses) in the nineteenth and twentieth centuries (licenses have only recently become available, generous access granted by The National Archives). This project will explore whether short sentences contributed to repeat offending, and whether early release schemes accelerated or inhibited recidivism. It investigates the financial costs of imprisonment to the country (and the human costs to those imprisoned) and does this over a significant period of time (allowing an examination of how repeated incarcerations affected the whole of an offender's criminal career). It concludes by asking what lessons can be learnt for today's debates about sentencing offenders and managing the prison population? Data was derived from the following sources: PCOM 3 (1853-1887, 1902-08, 1912-42) – these files contained 45,000 licenses and also the registers of license holders. They listed the prisoner’s name, sentence, where/when convicted, dates and conditions of the current license; previous convictions, age, previous occupation, when and from where the prisoner was released; and most had photographs of the prisoner. The National Archives granted us access to these records pre public release (they are now available on Find-My-Past and Ancestry). Criminal Registers 1853-1892 (contained offenders tried for indictable crimes, whether they were found guilty, details of the offence, and sentence imposed). Where possible we traced these offences in the Quarter Sessions Calendars in order to trace the antecedent criminal history. From these main sources, we were then able to trace prisoners released on license using a wide variety of other extant sources. These sources provided us with a considerable amount of additional information on offenders who were released on license: Census returns from 1841-1911 censuses (which gave details of the residence, family status, and occupation, of each person we will be searching for). Online Birth, Marriage and Death indices (which detailed if and when our offender was married, and had children; and, of course, when they died). Military records (mainly referring to World War One; these included service records - which in turn included disciplinary breaches - medal indices and pensions details. Metropolitan Police records including Habitual Criminal Registers (MEPO 6) which contain details of criminals as defined by sections 5-8 of the Prevention of Crimes Act 1871. From the sources above we constructed approximately 650 life grids. These were divided into an early (1853-55 n=62), middle (1871-73 n=201), and late (1885-1887 n=184) tranche, for 356 men and 288 women. Each life-grid charted offending/life histories for each offender. Studies funded by Leverhulme Trust (F/00130/H)) and ESRC (RES-062-23-0416) used life grids and `whole-life’ research methods and the method is now well-tested. The life-grid data was then entered into excel and SPSS in order to produce quantifiable data on - the progress of their criminal careers, their periods of incarceration, their employment careers, life events such as marriage, death of parents, and other significant life events. We had over two hundred thousand fields of data at the conclusion of our data collection/analysis. By analysing each of the life grids we were able to see the relationships and connections between life events and offending post-imprisonment (both short and long periods of custody, whilst on licence, and after license had expired.

This study assessed the effects of male inmate religiosity on post-release community adjustment and investigated the circumstances under which these effects were most likely to take place. The researcher carried out this study by adding Federal Bureau of Investigation criminal history information to an existing database (Clear et al.) that studied the relationship between an inmate's religiousness and his adjustment to the correctional setting. Four types of information were used in this study. The first three types were obtained by the original research team and included an inmate values and religiousness instrument, a pre-release questionnaire, and a three-month post-release follow-up phone survey. The fourth type of information, official criminal history reports, was later added to the original dataset by the principal investigator for this study. The prisoner values survey collected information on what the respondent would do if a friend sold drugs from the cell or if inmates of his race attacked others. Respondents were also asked if they thought God was revealed in the scriptures, if they shared their faith with others, and if they took active part in religious services. Information collected from the pre-release questionnaire included whether the respondent attended group therapy, religious groups with whom he would live, types of treatment programs he would participate in after prison, employment plans, how often he would go to church, whether he would be angry more in prison or in the free world, and whether he would be more afraid of being attacked in prison or in the free world. Each inmate also described his criminal history and indicated whether he thought he was able to do things as well as most others, whether he was satisfied with himself on the whole or felt that he was a failure, whether religion was talked about in the home, how often he attended religious services, whether he had friends who were religious while growing up, whether he had friends who were religious while in prison, and how often he participated in religious inmate counseling, religious services, in-prison religious seminars, and community service projects. The three-month post-release follow-up phone survey collected information on whether the respondent was involved with a church group, if the respondent was working for pay, if the respondent and his household received public assistance, if he attended religious services since his release, with whom the respondent was living, and types of treatment programs attended. Official post-release criminal records include information on the offenses the respondent was arrested and incarcerated for, prior arrests and incarcerations, rearrests, outcomes of offenses of rearrests, follow-up period to first rearrest, prison adjustment indicator, self-esteem indicator, time served, and measurements of the respondent's level of religious belief and personal identity. Demographic variables include respondent's faith, race, marital status, education, age at first arrest and incarceration, and age at incarceration for rearrest.

South Africa: Number of prisoners per 100,000 people: The latest value from 2017 is 279 prisoners per 100,000 people, a decline from 287 prisoners per 100,000 people in 2014. In comparison, the world average is 182 prisoners per 100,000 people, based on data from 146 countries.
