2025 KFF Marketplace Enrollees Survey

If the amount they pay in premiums doubled, about one in four enrollees in ACA Marketplace health plans say they would “very likely” go without insurance in 2026, finds a KFF survey of Marketplace enrollees fielded shortly after open enrollment began in the first weeks of November 2025.

The Uninsured Population and Health Coverage

This Health Policy 101 chapter examines the share of the United States population who are uninsured, highlighting their demographics and the challenges they face because of the lack of coverage.

How Many Uninsured Are in the Coverage Gap?

This analysis estimates that 1.4 million uninsured individuals in the 10 states without Medicaid expansion, including many working adults, people of color, and those with disabilities, remain in the “coverage gap,” ineligible for Medicaid or for tax credits that would make coverage ACA's Marketplaces affordable to them.

Key Facts about the Uninsured Population

The number of people ages 0-64 who were uninsured held steady at 25.3 million in 2023, although the number of uninsured children rose from 3.8 million to 4.0 million. Most uninsured people are in low-income families and have at least one worker in the family.

How the Unwinding Affected Enrollees

Over half who were disenrolled say they put off needed medical care while trying to renew Medicaid. Overall, 19% of adults who had Medicaid prior to the start of unwinding say they were disenrolled at some point in the past year. Of this group, a large majority (70%) were left at least temporarily uninsured.

  • Coverage Expansions and the Remaining Uninsured: A Look at California During Year One of ACA Implementation

    Report

    California is a bellwether state for understanding the impact of the Affordable Care Act (ACA). Much attention has been paid to enrollment in California's new coverage options, such as the Medicaid expansion (Medi-Cal) and plans sold through ACA marketplaces (Covered California), and to changes in the uninsured from 2013 to 2014. However, less is known about how this coverage has affected people’s access to care and financial security, and why others remain uninsured.
