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.

This is the fifth national survey of its kind. CLA (formerly the Association of State Correctional Administrators) and the Liman Center launched these longitudinal data collections in 2014. CLA is a national organization representing directors of corrections.
