The nation’s prison population grew for the second consecutive year in 2023, reversing more than a decade of steady decline.

A new prison population report from the federal Bureau of Justice Statistics, released before the federal shutdown, shows that 1,254,224 people were incarcerated in state and federal prisons on the last day of 2023 — an increase of 24,081 people from the year before, or about 2%. 

It follows a rise in 2022, which marked the first uptick since 2010, when prison populations began a gradual decline after peaking in the mid 2000s.

Even with recent increases, the prison population in 2023 was still about 20% below the 2013 level.

The latest figures show that women remain a small share of the prison population, but their numbers are growing faster than men’s. 

Between 2022 and 2023, the female prison population rose nearly 4%, from 87,800 to 91,100. The male population increased by nearly 2% during the same period. Thirty-eight states saw growth in their male prison populations, while 41 states reported increases among women.

New Mexico, Maine and South Dakota recorded the highest growth rates in their prison populations. 

Seven more populous states — Florida, Georgia, North Carolina, New York, Ohio, Texas and Wisconsin — added more than 1,000 people to their prison rolls during the same period. New Jersey, Alaska and Hawaii had the largest decreases in rates.

The growth comes as prisons are grappling with another demographic shift: a rapidly aging population. In 2023, nearly 1 in 4 prisoners were 50 or older. That trend is expected to continue, some experts say, with projections that by 2030 as much as one-third of the U.S. prison population will be over 50.

Correctional systems, many of which already face staffing shortages and overcrowding, are under growing pressure as prison populations rise. In recent years, some prisoner advocates and state legislators have pushed for measures such as “second look” laws or expanded parole eligibility that would release people deemed low risk for reoffending. Those could include older adults, people with serious medical needs and those convicted of nonviolent offenses.

The idea has gained traction as a way to lower prison operation costs and ease strain on correctional staff, but it remains controversial. Supporters say targeted decarceration can improve safety inside prisons and save taxpayer dollars, while opponents argue it could jeopardize public safety and that such releases may not significantly lower taxpayer costs.

America’s prison population is growing older at a pace that some experts say is unsustainable. As of 2022, the latest year with available data, people 55 and over made up nearly 1 in 6 prisoners — a fourfold increase since 2000 — and their numbers are projected to keep rising.

A new report from the American Civil Liberties Union and the Prison and Jail Innovation Lab at the University of Texas at Austin warns that this trend is straining correctional systems that were not designed to care for older adults.

If current trends continue, the authors estimate that by 2030 as much as one-third of the U.S. prison population will be over 50.

“It puts it into perspective how bad that this has gotten,” said Alyssa Gordon, the report’s lead author. Gordon is an attorney and legal fellow with the ACLU National Prison Project. “People don’t realize that prisons are woefully equipped to handle this crisis.”

The findings are based on data from public records requests to all 50 state corrections departments, publicly available state prison population datasets and the U.S. Bureau of Justice Statistics. Some data, however, were not available for every state, limiting the authors’ ability to make extended state-by-state comparisons.

The report’s findings come as states face competing pressures: a nationwide crackdown on crime and public safety, tightening corrections budgets and severe overcrowding and staffing shortages.

The aging prison population is largely a product of the “tough-on-crime” era of the 1980s and 1990s, when lawmakers at both the state and federal level enacted a wave of punitive policies under the banner of public safety, according to the report. These policies, including mandatory minimums, “three strikes” laws and “truth-in-sentencing” statutes, led to significantly longer sentences and fewer opportunities for early release. Experts say many of those policies remain in place today.

The report also highlights the growing price tag of incarcerating an aging population. Corrections spending data shows an upward trend in medical costs across some states, according to the report.

Prisons often lack accommodations for older adults, including accessible showers and beds, dementia care and hospice services, putting them at greater risk of injury or premature death, according to the report.

Emergency protocols also are frequently inadequate, the authors found, leaving older prisoners particularly vulnerable during natural disasters, disease outbreaks and other emergencies.

Some experts say that the costs of incarcerating older adults could create common ground for policymakers, as reducing this population may lower prison spending without significantly affecting public safety.

“If you want to figure out which population to target where it doesn’t have a public safety implication, this is the population to turn to,” Michele Deitch, one of the report’s authors and the director of the Prison and Jail Innovation Lab, told Stateline. “This is an issue that can gather bipartisan support.”

The report’s authors estimate that more than half of incarcerated people over 55 — more than 58,000 individuals — have already served at least 10 years, with nearly 16,000 behind bars for more than half their lives.

Older adults are less likely to reoffend, with recidivism rates reported at 18% in Colorado in 2020, 12% in South Carolina in 2021, and 6% in Florida in 2022. These rates are far below the national three-year rearrest rate of 66% for the general prison population, according to the report.

In recent years, more states have explored measures to address the aging prison population, including legislation commonly called “second look” laws or policies that expand parole eligibility for older or seriously ill inmates.

Most recently, a new Maryland law, which is set to take effect on Oct. 1, will allow certain incarcerated people to apply for geriatric parole. The law applies to those who are at least 65, have served at least 20 years, are not sex offenders, are serving sentences with the possibility of parole, and have had no serious disciplinary infractions in the past three years.
