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. One in three say they would be “very likely” to look for a lower-premium Marketplace plan.

Health Coverage Among Community Health Center Patients, 2019-2024

Community Health Center Patients, Financing, and Services

Changes to Medicaid and the ACA Marketplace included in the 2025 reconciliation law and the expiration of ACA Marketplace enhanced premium tax credits at the end of 2025 are likely to increase the number of uninsured patients and patients who cannot afford out-of-pocket costs, placing new financial burdens on community health centers.

Data and analysis

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.

  • Sources of Payment for Uncompensated Care for the Uninsured

    Issue Brief

    This brief estimates the level of public funding that was paid to help offset providers’ uncompensated care costs for the uninsured in 2017. To conduct the analysis, we rely on several secondary data sources including government budget appropriations and expenditure data for major public programs that provided funds to cover the cost of care for the uninsured, as well as analyses of secondary data sources completed by others.

  • Declines in Uncompensated Care Costs for The Uninsured under the ACA and Implications of Recent Growth in the Uninsured Rate

    Issue Brief

    The increase in the uninsured rate in recent years, as well as loss of coverage during the pandemic, has led to attention on the consequences of being uninsured. The need for medical care to test, treat, or prevent COVID-19 has also highlighted the potential consequences of uncompensated care for uninsured people. Uncompensated care costs occur because, although people who are uninsured use less care than people with coverage, most who are uninsured have limited income or resources and cannot afford the high cost of medical care, if and when they do need or use health care.

  • Medicaid Officials Anticipate Sharp Enrollment Declines and Increases in State Spending on Medicaid as Pandemic-Era Policies Continue to Unwind

    News Release

    The 23rd annual survey of state Medicaid directors finds that states expect national Medicaid enrollment will decline by 8.6% in state fiscal year (FY) 2024 as state Medicaid agencies continue to unwind pandemic-related continuous enrollment protections. After reaching record high enrollment, these estimates reflect a dramatic year-over-year decline in program enrollment from that high.

  • Navigating the Unwinding of Medicaid Continuous Enrollment: A Look at Enrollee Experiences

    Report

    To better understand the experiences of Medicaid enrollees who have completed the renewal process since the start of the unwinding period, KFF conducted five virtual focus groups in September to learn about their experiences with Medicaid, awareness of the end of the continuous enrollment provision, experiences renewing their coverage since the start of the unwinding, and if they were disenrolled, efforts to regain Medicaid or transition to other coverage.

  • 2022 Survey of ACA Marketplace Assister Programs and Brokers

    Report

    This survey of Marketplace assister programs and brokers tracks the experiences of professionals signing people up for Affordable Care Act coverage. It also examines the role that these programs expect to play when the COVID-19 public health emergency (PHE) ends, potentially ending Medicaid eligibility for millions of Medicaid enrollees.

  • How Many People Might Lose Medicaid When States Unwind Continuous Enrollment?

    Issue Brief

    Between 8 and 24 million people across the U.S. could be disenrolled from Medicaid during the unwinding of the program’s continuous enrollment provision. KFF's new analysis offers three illustrative scenarios for how state-level Medicaid enrollment could decline between March 2023 and May 2024, ranging from 8 percent to 28 percent of total enrollees. 

  • Eliminating the ACA: What Could It Mean for Medicaid Expansion?

    Policy Watch

    The debate over filling the Supreme Court seat previously held by Ruth Bader Ginsburg has brought renewed attention to the possibility of the Affordable Care Act (ACA) being overturned under the court challenge in California v. Texas, currently scheduled to be heard shortly after the election this November. The expansion of Medicaid was a central component of the ACA, and 39 states have now adopted the ACA expansion into their Medicaid programs. Because Medicaid is administered by states, under federal guidelines, there may be some confusion about how overturning the federal law would affect state Medicaid programs.

  • Kaiser Health Policy Tracking Poll: December 2014

    Feature

    With many of the Affordable Care Act’s (ACA) major provisions taking effect this past year, the December Kaiser Health Tracking Poll finds that many Americans are aware of the main parts of the law and, with the exception of the individual mandate, at least 6 in 10 feel favorably towards them. The poll finds the vast majority of the uninsured don’t know the deadline to enroll, most expect to get health insurance in the next few months, and nearly two-thirds say they don’t think they’ll have to pay a fine, or don’t know if they will, for not having coverage this year.
