Despite concerns and debates about the policy of using extended solitary confinement for managing individuals deemed to be too violent or disruptive to be controlled any other way—for the broader goal of system order and safety—empirical assessments of disparities in placements into this form of incarceration are limited. Prior studies typically have not compared extended solitary management (ESM) populations to general prison populations or dimensions along which disparities in ESM placements may arise. This paper identifies groups that may be more likely to be placed in ESM and policy concerns unique to each. Drawing on a study of one large state prison system, we examine disparities in ESM placement, including multiple, early, and longer duration placements. Implications of these disparities and the possibility that there may be differential experiences in and effects of ESM are discussed.
