Who Enrolls in Coverage and Who Remains Uninsured? Medicaid Take‐Up Before and After the Affordable Care Act and During Unwinding

From the pre- to post-ACA period, Medicaid take-up rates among eligible individuals increased, and these gains persisted during the beginning of the unwinding period, potentially reflecting increased outreach efforts under the Biden administration. However, areas of vulnerability remain among young adults, working adults, AI/AN individuals, and those in rural areas. These findings have important implications as the unwinding period ends, and large changes to Medicaid may be considered after the 2024 elections.
