A growing number of states are trying to support reentry for justice-involved individuals by providing Medicaid services prior to release from prison or jail through a Section 1115 demonstration waiver. This issue brief identifies unique opportunities states should consider when designing evaluation plans specific to their justice-involved populations, provides an overview of justice-involved 1115 demonstration initiatives, and summarizes what is known from existing evaluations of these activities.

SHADAC researchers have long monitored and investigated the magnitude, causes, and effects of the Medicaid undercount across surveys such as the American Community Survey (ACS) and Current Population Survey Annual Social and Economic Supplement (CPS ASEC) and its prevalence across states and populations. Two recent SHADAC publications investigate the large increase in the size of the undercount in the 2021 ACS.
