This report examines the use of disciplinary or administrative segregation or solitary confinement in U.S. prisons and jails, including —

  • the percentage of prison and jail inmates who were currently held in restrictive housing, those who had spent any time in restrictive housing in the last 12 months or since coming to the facility, if less than 12 months, and the total time spent in restrictive housing
  • prevalence rates for inmates by selected demographic characteristics, criminal justice status and history, current and past mental health status, and indicators of misconduct while in the facility
  • the relationship between the use of restrictive housing and facility-level characteristics, such as measures of facility disorder and facility composition.

Findings are based on data from the National Inmate Survey (NIS), 2011-12, conducted in 233 state and federal prisons and 358 local jails, with a sample of 91,177 inmates nationwide.
