Prison Reform in the United States. Efforts to Improve Conditions and Post-Release Outcomes

Most Americans don’t know what it’s like inside the United States’ 1,664 state and federal prisons. Yet even those who believe the primary purpose of incarceration is to deter crime or to inflict punishment expect that people returning home from prison should be ready to be productive, law-abiding members of their communities. Indeed, a 2025 Brennan Center poll found that more than 80 percent of likely voters think that formerly incarcerated people deserve a second chance and can be prepared to reenter society through rehabilitative, educational, or vocational programs.
Some correctional leaders are recognizing this and implementing innovative programs to set incarcerated people up for success. These reforms improve conditions for the people who live and work in prisons and, if adopted more widely, could also improve public safety.
But most prisons rarely offer such opportunities. Life behind bars is marked by social and physical isolation and punctuated by violence and brutality. People who have regular contact with U.S. prisons — law enforcement officers, correctional staff, lawyers, academics, nonprofit leaders, volunteers, and of course those who have been incarcerated and their loved ones — have referred to them as “warehouses that degrade and brutalize” and places where people have been “thrown away.” Judges have described the conditions in some U.S. prisons as objectively inhumane, with one saying such conditions have “no place in civilized society.” As of February 2026, the Department of Justice had 43 open investigations into jails, prisons, or entire state correctional systems for constitutional violations relating to physical and sexual violence, sanitation problems, staffing deficiencies, inadequate medical and psychiatric care, overuse of solitary confinement, and crowding.6 And as the Correctional Leaders Association has noted, the people who work in these systems suffer themselves.
