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.

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.

The map is based on Bureau of Justice Statistic (BJS) annual statistic on prison population. It was combined with the annual population estimates from Census to compute female prisoners per 100k population. The top 10 states with largest male prison population per 100k in 2004 are Delaware, Oklahoma, Texas, Mississippi, Louisiana, Montana, Arizona, Idaho, Missouri, Connecticut. Compared to top ten states for Male prisoners, which are all in south, the top 10 female prisoner states do not show geographic concentration. Data for Wash. DC is not reported, according to BJS, the "responsibility for felons was transferred to the Federal Bureau of Prisons". Only those female prisoners with one or more years of sentence are included.

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.

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.

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 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 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 ratesApart from the general population size, there are other factors which can be taken into consideration, such as a diversity in justice systems.

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 2024 Turkey had the highest incarceration rate among European countries, at 356 prisoners per 100,000 inhabitants, followed by Azerbaijan, which had an incarceration of 264. The country with the lowest incarceration rate in this year was Liechtenstein, which had 20 people in prison for every 100,000 inhabitants. Germany had one of the lowest rates of 72 when compared with other major European countries such as France and England & Wales, which had rates of 111 and 145 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.

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.

Mexico had nearly 236,773 prisoners as of January 2024, around 3,500 prisoners more than the prior year. The volume of imprisoned people in the country followed an increasing trend from 2018 to 2024. 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.

Figures in this chart may not align with others due to differences in counting methods.

The Holocaust was the systematic extermination of Europe's Jewish population in the Second World War, during which time, up to six million Jews were murdered as part of Nazi Germany's "Final Solution to the Jewish Question". In the context of the Second World War, the term "Holocaust" is traditionally used to reference the genocide of Europe's Jews, although this coincided with the Nazi regime's genocide and ethnic cleansing of an additional eleven million people deemed "undesirable" due to their ethnicity, beliefs, disability or sexuality (among others). During the Holocaust, Poland's Jewish population suffered the largest number of fatalities, with approximately three million deaths. Additionally, at least one million Jews were murdered in the Soviet Union, while Hungary, Latvia, Lithuania, the Netherlands and Yugoslavia also lost the majority of their respective pre-war Jewish populations. The Holocaust in Poland In the interwar period, Europe's Jewish population was concentrated in the east, with roughly one third living in Poland; this can be traced back to the Middle Ages, when thousands of Jews flocked to Eastern Europe to escape persecution. At the outbreak of the Second World War, it is estimated that there were 3.4 million Jews living in Poland, which was approximately ten percent of the total population. Following the German invasion of Poland, Nazi authorities then segregated Jews in ghettos across most large towns and cities, and expanded their network of concentration camps throughout the country. In the ghettos, civilians were deprived of food, and hundreds of thousands died due to disease and starvation; while prison labor was implemented under extreme conditions in concentration camps to fuel the German war effort. In Poland, six extermination camps were also operational between December 1941 and January 1945, which saw the mass extermination of approximately 2.7 million people over the next three years (including many non-Poles, imported from other regions of Europe). While concentration camps housed prisoners of all backgrounds, extermination camps were purpose-built for the elimination of the Jewish race, and over 90% of their victims were Jewish. The majority of the victims in these extermination camps were executed by poison gas, although disease, starvation and overworking were also common causes of death. In addition to the camps and ghettos, SS death squads (Einsatzgruppen) and local collaborators also committed widespread atrocities across Eastern Europe. While the majority of these atrocities took place in the Balkan, Baltic and Soviet regions, they were still prevalent in Poland (particularly during the liquidation of the ghettos), and the Einsatzgruppen alone are estimated to have killed up to 1.3 million Jews throughout the Holocaust. By early 1945, Soviet forces had largely expelled the German armies from Poland and liberated the concentration and extermination camps; by this time, Poland had lost roughly ninety percent of its pre-war Jewish population, and suffered approximately three million further civilian and military deaths. By 1991, Poland's Jewish population was estimated to be just 15 thousand people, while there were fewer than two thousand Jews recorded as living in Poland in 2018.

Additional information on religion in United States prisons

The religious affiliation of inmates in the United States, the country with most prisoners per head globally, is reasonably similar to the religious affiliations of the society overall. That said, the proportion of non-religious inmates and those declining to express their religious affiliation is smaller than the overall proportion. In contrast the number of Muslim inmates is disproportionately large in comparison with wider society. As a result a sizable share of prison chaplains identity as Muslim, catering to the preferences of the Muslim prison population.

Following the September 11, 2001 World Trade Centre attacks and the subsequent War on Terror launched by George W. Bush, religious extremism has been a target of public debate and policy. The debate has stretched into prisons particularly with the United States prison on Guantanamo Bay holding a number of suspected terrorists related to religious extremism. In turn, fears have been raised that prisons have become a hotbed for religious extremism.

Critics have argued that religious extremism has provided an unwarranted justification for the conviction of Muslims. Regardless of the supposed reason for their imprisonment, this disproportionate number presents a problem for United States policy makers.

This dataset shows the number of people that are in prison by state in 2006 and 2007. These numbers are then compared to show the difference between the two years and a percentage of change is given as well.
