Mapping ACA Marketplace and Medicaid Enrollment by Congressional District
With an estimated 14 million people expected to become uninsured by 2034 due to major changes to Medicaid and the Affordable Care Act (ACA) Marketplaces in the 2025 reconciliation law plus the expiration of the ACA’s enhanced premium tax credits, KFF’s new interactive maps provide a way to view ACA Marketplace and Medicaid enrollment by congressional district across the U.S.
