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.

With approximately 1.7 million prisoners, China had by far the biggest prison population across the Asia-Pacific region in 2022. In contrast, less than one thousand people were incarcerated in Brunei and Timor-Leste, respectively.

Prison populations and total populations

The 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 1.4 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 rates

Apart 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.

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.

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

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.

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.

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 United Nations International Crime Prevention and Criminal Justice Branch began the Surveys of Crime Trends and Operations of Criminal Justice Systems (formerly known as the World Crime Surveys) in 1978. The goal of the data collection effort was to conduct a more focused inquiry into the incidence of crime worldwide. To date, there have been five quinquennial surveys, covering the years 1970-1975, 1975-1980, 1980-1986, 1986-1990, and 1990-1994, respectively. Starting with the 1980 data, the waves overlap by one year to allow for reliability and validity checks of the data. For this data collection, the original United Nations data were restructured into a standard contemporary file structure, with each file consisting of all data for one year. Naming conventions were standardized, and each country and each variable was given a unique identifying number. Crime variables include counts of recorded crime for homicide, assault, rape, robbery, theft, burglary, fraud, embezzlement, drug trafficking, drug possession, bribery, and corruption. There are also counts of suspects, persons prosecuted, persons convicted, and prison admissions by crime, gender, and adult or juvenile status. Other variables include the population of the country and largest city, budgets and salaries for police, courts, and prisons, and types of sanctions, including imprisonment, corporal punishment, deprivation of liberty, control of freedom, warning, fine, and community sentence. The countries participating in the survey and the variables available vary by year.

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.

On March 16th 2025, Trump's administration deported 238 alleged members of the Venezuela criminal gang Tren de Aragua to the Terrorism Confinement Center (or CECOT) prison in El Salvador. According to official data, the United States will pay around six million U.S. dollars to El Salvador to imprison around 300 deportees from the U.S. for one year. Crime in El Salvador Nayib Bukele is one of the most beloved world leaders, with an approval rate of 93 percent as of July 2024, being crowned with the highest in Latin America. This comes not without a reason, as El Salvador used to be constantly ranked as one of the most violent countries globally due to gang violence, specifically, La Mara Salvatrucha (MS-13) and Mara Barrio-18. After a particularly violent couple of days in March 2022, Bukele’s administration called for an Emergency state, with massive incarceration of alleged gang members. The Central American country now ranks with the lowest homicide rate in the region. One of the largest prisons in the world, not without controversy El Salvador ranks by far as the country with the highest incarceration rate in the world. As of February 2025, El Salvador's rate was 1,659 prisoners per 100,000 inhabitants, more than double when compared to Cuba – which ranks as the second place. The massive incarceration and the measures taken during the emergency state, various countries and international observers called out El Salvador for an approach lacking human rights. As the gang members were heavily mistreated and later on some of them, or their families, were charged 170 US dollars a month for food, clothing, and other services. Nonetheless, the effectiveness of such measures and with almost 90 percent of Salvadoreans feeling safer after the emergency state, Bukele secured a second office term in 2024 with more than 80 percent of the votes.

Mexico had nearly 233,300 prisoners as of December 2023, around 7,200 prisoners more than the prior year. The volume of imprisoned people in the country followed an increasing trend from 2018 to 2023. Prison population That figure places Mexico among the countries with the largest number of prisoners in the world. However, when taking into account incarceration rates, that is, the number of prisoners per 100,000 inhabitants, Mexico falls out of the ranking and is, actually, one of the Latin American and Caribbean countries with the lowest rates, exceeded by far by countries like El Salvador and Cuba, which register four times the prison population rate of Mexico.People aged 30 to 39 years made up for the largest share of prisoners in Mexico. However, the share of people deprived of liberty whose age ranged from 18 to 29 years was significantly largest in the case of women, with 32.1 percent of female prisoners pertaining to such age group, while in the case of men it fell to 25.1 percent. Regarding female inmates, approximately a tenth have been pregnant while being in jail. Furthermore, theft was the most commonly committed crime by women in Mexican states' penitentiary centers in 2022, followed by kidnapping and homicide. Preventive prison The main reason for the rapid growth of prison population in Mexico in recent years is the 2019 reform of the article 19 of the Constitution, which has led to the spread of pretrial detention. Pretrial detention is a measure that leads to the imprisonment of people automatically while they are still being investigated, without having been sentenced, and can last up to two years. The reform allowed for automatic preventive imprisonment for a wider range of crimes than before, with the new list including fuel theft (huachicoleo) and burglary, among others. This affects particularly vulnerable people from poor backgrounds, with low education and who commit petty crimes. As of December 2020, 78.6 percent of pre-trial detainees for robbery in Mexico had not been sentenced, which means that less than a fourth of people in jail for robbery had been found guilty in court. The country had an even higher share of unsentenced prisoners for drug trafficking, with 87.8 percent of people being in preventive detention without charge.. One of the reasons behind the high share of prisoners awaiting sentence is the large number of simultaneous cases that public defenders have to attend to. Depending on the Mexican state in which someone is being prosecuted, a public defender can have up to an average of 336.9 simultaneous cases to defend.
