People in prisons and jails are disproportionately likely to have chronic health problems including diabetes, high blood pressure, and HIV, as well as substance use and mental health problems. Nevertheless, correctional healthcare is low-quality and difficult to access. It’s also expensive: Astonishingly, most prisons charge incarcerated people a copay for doctor visits.

The downstream effects — for both incarcerated people and the general public — have been disastrous: Mass incarceration has shortened the overall U.S. life expectancy by 5 years.

Below is our key research into the public health effects of incarceration:

Chronic Punishment: The unmet health needs of people in state prisons

We break down the most recent national data on incarcerated people’s health, showing how prisons are neglecting the health problems of many in their care.

Our COVID-19 resources

Find our three major reports on COVID-19 in prisons and jails, as well as a list of policy recommendations, an explainer on social distancing behind bars, a powerful fact sheet, and much more. We also tracked where pandemic-related policy changes took place.

Arrest, Release, Repeat: How police and jails are misused to respond to social problems

At least 4.9 million people go to county and city jails each year, our national analysis shows. We find that people who go to jail - particularly those who go more than once a year - are more likely to have preexisting health problems.

Briefings

• Addicted to punishment: Jails and prisons punish drug use far more than they treat it, by Emily Widra, January 30, 2024
  Despite the common refrain that jails and prisons are "de facto treatment facilities," most prioritize punitive mail scanning policies and strict visitation rules that fail to prevent drugs from entering facilities while providing little to no access to treatment and healthcare.
• The aging prison population: Causes, costs, and consequences by Emily Widra, August 2, 2023
  New Census Bureau data show the U.S. population is getting older — and at the same time, our prison populations are aging even faster. In this briefing, we examine the inhumane, costly, and counterproductive practice of locking up older adults.
• Heat, floods, pests, disease, and death: What climate change means for people in prison, by Leah Wang, July 19, 2023
  Without consistent access to relief or safer environments, incarcerated people are punished with deadly heat, increased biological threats, and flimsy emergency protocols. We explain new epidemiological evidence confirming that heat and death are linked in prisons nationwide, and explain why the climate-change-induced plight of people in prisons deserves swift action.
• New data on HIV in prisons during the COVID-19 pandemic underscore links between HIV and incarceration, by Emily Widra, June 1, 2023
  The percent of people in prison with HIV barely budged despite the heightened risks of COVID-19 to immunocompromised individuals. We review the evidence connecting the parallel epidemics of HIV and incarceration, which disproportionately impact Black men in the South.
• Mortality, health, an poverty: the unmet needs of people on probation and parole, by Emily Widra and Alexi Jones, April 3, 2023
  Unique survey data reveal that people under community supervision have high rates of substance use and mental health disorders and extremely limited access to healthcare, likely contributing to the high rates of mortality.
• How a Medicare rule that ends financial burdens for the incarcerated leaves some behind, by Emily Widra, January 3, 2023
  Medicare expands enrollment periods for people released from prison after January 1, 2023, but offers no relief for people who have been paying premiums for zero Medicare benefits while incarcerated, nor for those released before 2023 who signed up late and are stuck paying jacked-up premiums for the rest of their life.
• What the end of Roe v. Wade will mean for people on probation and parole, by Wendy Sawyer and Wanda Bertram, June 30, 2022

  Forty states and the federal prison system continue to charge incarcerated people unaffordable copays for medical care.
• Recent studies shed light on what reproductive “choice” looks like in prisons and jails, by Katie Rose Quandt and Leah Wang, December 8, 2021
  States that are otherwise hostile to abortion rights are especially likely to make it difficult for incarcerated people.
• Unsupportive environments and limited policies: Pregnancy, postpartum, and birth during incarceration, by Leah Wang, August 19, 2021
  Recent data offers an unprecedented, detailed look at pregnancy and postpartum experiences in prison. Findings indicate that jails, prisons, and youth facilities have yet to adequately recognize pregnancy and postpartum needs either in policy or in practice.

• New data: State prisons are increasingly deadly places, by Leah Wang and Wendy Sawyer, June 8, 2021
  New data from the Bureau of Justice Statistics shows that state prisons are seeing alarming rises in suicide, homicide, and drug and alcohol-related deaths.

  Incarceration can trigger and worsen symptoms of mental illness — and those effects can last long after someone leaves the prison gates.
• The research is clear: Solitary confinement causes long-lasting harm, by Tiana Herring, December 8, 2020
  At the International Symposium on Solitary Confinement, researchers and formerly incarcerated people made it clear that isolation causes severe and permanent damage.
• New data: Solitary confinement increases risk of premature death after release, by Andrea Fenster, October 13, 2020
  Any amount of time spent in solitary confinement increases the risk of death after release from prison, including deaths by suicide, homicide, and opioid overdose.
• Compassionate release was never designed to release large numbers of people, by Emily Widra and Wanda Bertram, May 29, 2020
  With help from artist Kevin Pyle, we explain why very few people who apply for compassionate release are approved — even during a pandemic.
• Deaths in state prisons are on the rise, new data shows. What can be done?, by Emily Widra, February 13, 2020
  Prison systems have shown they are unprepared and unwilling to care for an aging prison population - whether by improving healthcare or expanding compassionate release.
• New BJS report reveals staggering number of preventable deaths in local jails, by Alexi Jones, February 13, 2020
  In 2016, over 1,000 people died in local jails - many the tragic result of healthcare and jail systems that fail to address serious health problems among the jail population, and of the trauma of incarceration itself.

  13 states in the hottest parts of the country lack universal A/C in their prisons. We explain the consequences.

  For some incarcerated people, a visit to the doctor can cost almost an entire month’s pay, deterring people from seeking the care they need.
• Food for thought: Prison food is a public health problem by Wendy Sawyer, March 3, 2017
  We connect the dots between prison food, nutrition, and public health. The takeaway? Prison food is not just gross; it is often nutritionally inadequate.

Drug policy

One of the worst criminal justice policy failures — responding to drug use with punishment rather than care — also puts public health at risk.

Collateral consequences

Tens of millions of people are dealing with the “collateral consequences” of punishment: effects such as homelessness that last long after someone has served their sentence. These harms also impact public health.

Communication and contact

Visits and phone calls mitigate the harmful effects of prolonged isolation behind bars. But jails and prisons make staying in touch difficult, particularly for poor families.
