Time-In-Cell 2021 is the only comprehensive, current national data on the number of prisoners in solitary confinement — or what prison directors call restrictive housing — and the length of time prisoners are housed under these conditions. As of the summer of 2021, an estimated 41,000 to 48,000 prisoners in the United States were held in isolation for an average of 22 hours a day for 15 days or more. Moreover, three states reported holding no one in that form of isolation in July 2021; two other states reported fewer than ten people in solitary; and ten states reported not using solitary in any of their women’s prisons. In contrast, as documented in the study published in 2014, every jurisdiction reported using solitary confinement, and an estimated 80,000 to 100,000 people were in solitary confinement in prisons throughout the United States.

This research intersects with efforts around the country—spearheaded by people in confinement, by communities, by many organizations including of correctional leaders, and by legislators—to limit or end the use of isolation in prison. National campaigns (“Unlock the Box,” “Stop Solitary”) have brought attention to the harms, as has the recent death of Albert Woodfox, author of Solitary, who spent more than forty years in isolation at Louisiana’s Angola prison before he was released in 2016. Time-in-Cell also examined the demographics of people held in isolation, including its continued use for people whom their own jurisdiction defines as having “serious mental illness.” Moreover, the number of Black women held in solitary was higher than the number of white women.
