Using American Community Survey data from 2010-2019 and a difference-in-differences (DiD) research design, we test for changes in migratory trends between expansion and non-expansion states. In contrast with prior findings examining short-run effects, we find evidence of increased migration from non-expansion-toexpansion states among those with Medicaid coverage after the policy change. Staggered DiD methods indicate that increases in net migration to expansion states are driven by reduced out-migration from expansion states.
