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.

In 2022, about 1,826 Black men per 100,000 residents were imprisoned in the United States. This rate was much lower for Black women, at 64 per 100,000 residents. The overall imprisonment rate in 2022 stood at 355 per 100,000 Americans.

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.

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.

In 2023, 8,842 murderers in the United States were white, while 6,405 were Black. A further 461 murderers were of another race, including American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander. However, not all law enforcement agencies submitted homicide data to the FBI in 2023, meaning there may be more murder offenders of each race than depicted. While the majority of circumstances behind murders in the U.S. are unknown, narcotics, robberies, and gang killings are most commonly identified.

Saint Kitts and Nevis saw a murder rate of 65 per 100,000 inhabitants, making it the most dangerous country for this kind of crime worldwide as of 2023. 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. Meanwhile, Celaya in Mexico was the most dangerous city for murders. Violent conflicts worldwide Notably, these figures do not include deaths that resulted from war or a violent conflict. While there is a persistent number of conflicts worldwide, resulting casualties are not considered murders. Partially due to this reason, homicide rates in Latin America are higher than those in Afghanistan or Syria. A different definition of murder in these circumstances could change the rate significantly in some countries. Causes of death Also noteworthy is that murders are usually not random events. In the United States, the circumstances of murders are most commonly arguments, followed by narcotics incidents and robberies. Additionally, murders are not a leading cause of death. Heart diseases, strokes and cancer pose a greater threat to life than violent crime.

In 2023, the FBI reported that there were 9,284 Black murder victims in the United States and 7,289 white murder victims. In comparison, there were 554 murder victims of unknown race and 586 victims of another race. Victims of inequality? In recent years, the role of racial inequality in violent crimes such as robberies, assaults, and homicides has gained public attention. In particular, the issue of police brutality has led to increasing attention following the murder of George Floyd, an African American who was killed by a Minneapolis police officer. Studies show that the rate of fatal police shootings for Black Americans was more than double the rate reported of other races. Crime reporting National crime data in the United States is based off the Federal Bureau of Investigation’s new crime reporting system, which requires law enforcement agencies to self-report their data in detail. Due to the recent implementation of this system, less crime data has been reported, with some states such as Delaware and Pennsylvania declining to report any data to the FBI at all in the last few years, suggesting that the Bureau's data may not fully reflect accurate information on crime in the United States.

This statistic shows the number of releases on day and full parole from federal prisons in Canada from the fiscal year of 2006 to the fiscal year of 2022. In the fiscal year of 2022, 62 prisoners were released on full parole from federal prisons in Canada. ParoleParole is the conditional release of an offender that allows them to serve the remainder of their sentence in the community under supervision. There are two type of parole in Canada: day parole, and full parole. The purpose of day parole is to prepare the inmate for full parole or statutory release. The inmate is allowed to participate in community-based activities but must return to either a correctional institution or community residence in the evening. An inmate is eligible for day parole six months before they are eligible for full parole. Full parole allows offenders to serve part of their sentence in the community under supervision. They are allowed to live in a private residence but must report regularly to a parole supervisor. An offender is eligible for full parole when they have served either one-third of their sentence or seven years, whichever is less. Those convicted of first degree murder are eligible after 25 years. Second degree murderers are eligible between 10 and 25 years into their sentences. Day parole is granted much more frequently than full parole. In the fiscal year of 2022, 715.8 percent of day paroles were granted, while only 30.4 percent of full paroles were granted. In general, non-aboriginal offenders have been more likely to be granted parole over the last decade. Aboriginal offenders also serve more of their sentence, on average, than their non-Aboriginal counter parts.

This statistic shows the percentage of eligible days and full paroles from federal prisons approved in Canada from the fiscal year of 2006 to the fiscal year of 2022. In the fiscal year of 2022, 30.4 percent of offenders eligible for full parole were granted release in Canada.

This statistic shows the number of statutory releases from federal prisons in Canada from the fiscal year of 2006 to the fiscal year of 2022. In the fiscal year of 2022, 4,383 prisoners were released from federal prisons in Canada under statutory release.

The crime rate in the United Kingdom was highest in England and Wales in 2023/24, at 89.7 crimes per 1,000 people, compared with Scotland which had 55 crimes per 1,000 population and Northern Ireland, at 52.3 crimes per 1,000 people. During this time period, the crime rate of England and Wales has usually been the highest in the UK, while Scotland's crime rate has declined the most, falling from 93.4 crimes per 1,000 people in 2002/03, to just 52.3 by 2021/22. Overall crime on the rise In 2022/23 there were approximately 6.74 million crimes recorded by the police in England and Wales, with this falling to 6.66 million in 2023/24. Although crime declined quite significantly between 2002/03 and 2013/14, this trend has been reversed in subsequent years. While there are no easy explanations for the recent uptick in crime, it is possible that reduced government spending on the police service was at least partly to blame. In 2009/10 for example, government spending on the police stood at around 19.3 billion pounds, with this cut to between 17.58 billion and 16.35 billion between 2012/13 and 2017/18. One of the most visible consequences of these cuts was a sharp reduction in the number of police officers in the UK. As recently as 2019, there were just 150,000 police officers in the UK, with this increasing to 171,000 by 2023. A creaking justice system During the period of austerity, the Ministry of Justice as a whole saw its budget sharply decline, from 9.1 billion pounds in 2009/10, to just 7.35 billion by 2015/16. Although there has been a reversal of the cuts to budgets and personnel in the justice system, the COVID-19 pandemic hit the depleted service hard in 2020. A backlog of cases grew rapidly, putting a strain on the ability of the justice system to process cases quickly. As of the first quarter of 2023, for example, it took on average 676 days for a crown court case to go from offence to conclusion, compared with 412 days in 2014. There is also the issue of overcrowding in prisons, with the number of prisoners in England and Wales dangerously close to operational capacity in recent months.
