The National Academies of Sciences, Engineering, and Medicine convened a workshop on June 6, 2018. The workshop’s mission was to investigate the connection between incarceration and health inequities to better understand the distributive impact of incarceration on low-income families and communities of color. Topics of discussion focused on the experience of incarceration and reentry, mass incarceration as a public health issue, women’s health in jails and prisons, the effects of reentry on the individual and the community, and promising practices and models for reentry. The programs and models that are described in this publication are all Philadelphia-based because Philadelphia has one of the highest rates of incarceration of any major American city. This publication summarizes the presentations and discussions of the workshop.
