On any given day in the United States, 80,000 people are in solitary, with most in isolation 23 hours a day in a 6-by-9-foot cell with a steel door and no windows. No fresh air, no visual stimulation, no human contact.



Some Americans have been in solitary for 15, 20, 25 years or more. And like most layers of the American criminal justice system, solitary disproportionately impacts people of color.
