In 2019, 143 inmates of state and federal prisons in the United States were killed by homicide. This is a significant increase from 2008 levels, when 40 inmates were killed in state or federal prisons in the United States.

Two inmate deaths were classified as suicide in federal prisons in Canada in the fiscal year of 2023. A further 59 deaths were attributed to natural causes in that year.

Between 2012 and 2020, the number of self-inflicted deaths among white prisoners in public prisons in England and Wales went up from 49 to 57.

In 2024, there were 342 deaths in prison custody in England and Wales, compared with 311 in the previous year, and 371 in 2022, which was the most deaths reported during this time period.

Mortality in Correctional Institutions (MCI) (formerly, the Deaths in Custody Reporting Program (DCRP)), is an annual data collection conducted by the Bureau of Justice Statistics (BJS). The MCI collection began in 2000 under the Death in Custody Reporting Act of 2000 (P.L. 106-297). It is the only national statistical collection that obtains detailed information about deaths in adult correctional facilities. MCI collects data on persons dying in state prisons, local jails and in the process of arrest. Each collection is a separate subcollection, but each is under the umbrella of the MCI collection. This deals with the prison subcollection, which has a prison death file. The prison portion of Mortality in Correctional Institutions began in 2001 after the passage of the Deaths in Custody Reporting Act of 2000 in October of 2000. The prison component of MCI collects data on inmate deaths occurring in the 50 state departments of corrections while inmates are in the physical custody of prison officials.

The DCRP collects data on persons dying in state prisons, local jails and in the process of arrest. Each collection is a separate subcollection, but each is under the umbrella of the DCRP collection. The DCRP collects inmate death records from each of the nation's 50 state prison systems and approximately 2,800 local jail jurisdictions. In addition, this program collects records of all deaths occurring during the process of arrest. Data are collected directly from state and local law enforcement agencies. Death records include information on decedent personal characteristics (age, race or Hispanic origin, and sex), decedent criminal background (legal status, offense type, and time served), and the death itself (date, time, location, and cause of death, as well as information on the autopsy and medical treatment provided for any illness or disease). This data collection represents a single year of DCRP Jails data. The variable names and coding, while similar to other years, have not been standardized across years. The concatenated multi-year versions of the DCRP Jails population data have been edited to correct outliers and other data anomalies. Researchers are encouraged to use the concatenated multi-year data for final jail population data.

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 2019, there were 3,853 state prisoner fatalities in the United States. This is a decrease from the previous year, when there were 4,137 state prisoner fatalities. All causes of death have been considered. A list of the countries with the largest number of prisoners is accessible here.

The prison murders are broken down by the age of the perpetrators.

The Mortality In Correctional Institutions (MCI) data collection (formerly Deaths in Custody Reporting Program (DCRP)), collects quarterly inmate death records from each of the nation's 50 state prison systems, 50 state juvenile correctional authorities, and 3,095 local jails. In addition, the program collects quarterly records of all deaths during the process of arrest by each of the nation's 17,784 state and local law enforcement agencies. These death records include information on the deceased's personal characteristics (age, gender and race/ethnicity), their criminal background (legal status, offense types, length of stay in custody), and details of the death itself (the date, time, location and cause of each death, as well as information on autopsies and medical treatment provided for illnesses/diseases).

Abstract: Mortality in prisons, a basic indicator of the right to health for incarcerated persons, has never been studied extensively in Brazil. An assessment of all-cause and cause-specific mortality in prison inmates was conducted in 2016-2017 in the state of Rio de Janeiro, based on data from the Mortality Information System and Prison Administration. Mortality rates were compared between prison population and general population after standardization. The leading causes of death in inmates were infectious diseases (30%), cardiovascular diseases (22%), and external causes (12%). Infectious causes featured HIV/AIDS (43%) and TB (52%, considering all deaths with mention of TB). Only 0.7% of inmates who died had access to extramural health services. All-cause mortality rate was higher among prison inmates than in the state’s general population. Among inmates, mortality from infectious diseases was 5 times higher, from TB 15 times higher, and from endocrine diseases (especially diabetes) and cardiovascular diseases 1.5 and 1.3 times higher, respectively, while deaths from external causes were less frequent in prison inmates. The study revealed important potentially avoidable excess deaths in prisons, reflecting lack of care and exclusion of this population from the Brazilian Unified National Health System. This further highlights the need for a precise and sustainable real-time monitoring system for deaths, in addition to restructuring of the prison staff through implementation of the Brazilian National Policy for Comprehensive Healthcare for Persons Deprived of Freedom in the Prison System in order for inmates to fully access their constitutional right to health with the same quality and timeliness as the general population.

"Collects inmate death records from each of the nation's 50 state prison systems, Federal Bureau of Prisons, and approximately 2,800 local jail jurisdictions. Between 2003 and 2014, BJS also collected data on persons who died while in the process of arrest. Death records include information on decedent personal characteristics (age, race or Hispanic origin, and sex), decedent criminal background (legal status, offense type, and time served), and the death itself (date, time, location, and cause of death, as well as information on the autopsy and medical treatment provided for any illness or disease). Data collections covering these populations were developed in annual phases: Annual collection of individual death records from local jail facilities began in 2000, followed by a separate collection for state prison facilities in 2001. Collection of state juvenile correctional agencies began in 2002 but was discontinued in 2006, and collection of arrest-related death records began in 2003. Due to concerns regarding data quality and coverage issues, BJS temporarily suspended the arrest-related death (ARD) portion of the DCRP in 2014. Datasets are produced in an annual format. In 2016, the Department of Justice (DOJ) decided to place more emphasis on the section of Death in Custody Reporting Act reauthorization law (P.L. 113-242) that concerned non-compliance with the data collection. Per the law, states that did not report on a quarterly basis individual-level data on deaths occurring in local jails, in state prisons, or in the process of arrest, could be penalized up to 10% of their DOJ-sponsored Justice Assistance Grant (JAG) awards. As a federal statistical agency, BJS data may not be used for enforcement purposes. Therefore, DOJ determined that the Bureau of Justice Assistance (BJA) should manage collection of the data pursuant to the law, since BJA is not under similar requirements to collect data for statistical purposes only. (The Report of the Attorney General to Congress Pursuant to The Death in Custody Reporting Act, December 16, 2016, is located at: https://www.justice.gov/archives/page/file/918846/download) BJS finished collection of deaths that occurred during the 2019 calendar year in December, 2020, and formally closed the MCI collection on March 31, 2021."

In 2019, 2,144 white state prison inmates died in the United States. A further 1,174 Black or African American inmates died in that same year. In total, 3,853 United States state prison inmates died in 2019.

Non-natural deaths of inmates in custody.

In 2023, there were 14,327 murder offenders in the United States who were male, in comparison to 1,898 who were female. However, there were also 5,279 murder offenders where their gender was unknown. Homicides in the U.S. Murder and non-negligent manslaughter in the United States is defined as the willful killing of another human being. Justifiable homicides, or cases where a felon is killed by an officer in the line of duty or a felon is killed during a felony by a private citizen, are not included in murder counts by the Federal Bureau of Investigation (FBI). The total number of murders varies from state to state in the U.S., with more populous states having higher numbers of murders. Murder offenders and victims Most murder offenders in the United States are between the ages of 17 and 39, with the number of offenders declining steadily after age 40. Additionally, the highest rate of death by homicide was found among males between the ages of 15 and 24. The highest rate of death by homicide for females was for girls under the age of one.

The purpose of this survey is particularly important for monitoring trends in correctional populations. These data assist policy makers and corrections managers in formulating decisions based upon historical comparisons. Key indicator data also give some indication of current trends in the utilization of correctional services and provide a basis for calculating incarceration rates (number of persons incarcerated as a proportion of the Canadian population).
