30 Countries Bursting at the Seams With Prisoners, USA Ranks High
The American prison system is a deeply debated issue. According to Statista, approximately 1.8 million people were incarcerated in the U.S. at the end of 2023. While some Americans advocate abolishing mass incarceration, others want to see criminals serve longer sentences.
These numbers may seem large at first glance. But where does the U.S. rank alongside other countries’ prison populations?
Statista gathered data to rank the countries with the largest number of prisoners. You might be surprised to learn where the U.S. stands.
Measuring Incarceration Rates

Statista took data from the World Prison Brief created by the Institute for Criminal Policy Research to rank the 30 countries with the largest number of prisoners. The 2024 results show the number of incarcerations per 100,000 people in each country.
According to an Institute for Crime & Justice Policy Research report from 2021, approximately 10 million people were incarcerated worldwide. There’s been a rise in prisoner rates in some parts of the world. South America, for example, tripled its incarceration size between 2000 and 2021.

The World’s Largest Prison

El Salvador not only has the largest number of prisoners; it also holds another major distinction. The Latin American country is home to the world’s largest prison, which opened in February 2023. The prison, called the Center for the Confinement of Terrorism, can hold approximately 40,000 prisoners and is operated by a guard force of 650 people.
El Salvador’s need for this prison is said to be due to the extensive gang network operating there. President Nayib Bukele promised to detain as many criminals as possible, making constitutional exceptions to accomplish the task. It’s reported that the facility will also become the world’s most overcrowded prison.
America’s Large Incarceration Rate

The United States has the sixth highest number of prisoners worldwide, with nearly 2 million people behind bars. The prison system costs the U.S. approximately $182 million per year.
Some advocates have suggested that overturning drug convictions in the U.S. would greatly reduce the American prison population. Approximately 20% of incarcerated people are there for drug offenses.
The History of Prisons

The origins of prisons go back to 1000 BC with Mesopotamia and Egypt setting up holding cells for offenders who were sentenced to death or slavery. In the U.S., the country’s first penitentiary opened in 1790, which tried to create a larger, safer, and more sanitary space for prisoners.
Alcatraz, one of history’s most infamous high-security prisons, opened on an island in the San Francisco Bay in 1934. In 1989, California also opened the first supermax prison, which confines its prisoners to their cells for about 22 hours each day.
The rate of mass incarcerations rose drastically starting in the 1970s, with U.S. prisoners increasing from 161 per 100,000 residents to 767 per 100,000 between 1972 and 2007.
