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

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.

  • California’s Previously Uninsured After The ACA’s Second Open Enrollment Period

    Report

    The Kaiser Family Foundation California Longitudinal Panel Survey is a series of surveys that, over time, tracks the experiences and views of a representative, randomly selected sample of Californians who were uninsured prior to the major coverage expansions under the Affordable Care Act (ACA). The initial baseline survey was conducted with a representative sample of 2,001 nonelderly uninsured Californian adults in summer 2013, prior to the ACA’s initial open enrollment period. The second survey in the series followed up with the same group of previously uninsured Californians who participated in the baseline (a longitudinal panel survey). The third in the series, and the focus of this report, followed up with them again after the second open enrollment period in spring 2015 to find out whether more have gained coverage, lost coverage, or remained uninsured, what barriers to coverage remain, how those who now have insurance view their coverage, and to assess the impacts that gaining health insurance may have had on financial security and access to care.

  • Kaiser Health Tracking Poll: March 2015

    Feature

    As the Affordable Care Act (ACA) marks its fifth anniversary, this month’s poll finds the gap between favorable and unfavorable opinions of the law has narrowed to the closest margin in over two years.

Burwell case in early March, the majority of the public continues to say they have heard only a little or nothing at all about the case. The survey also includes a look at Americans’ experiences reporting their insurance status on their taxes for the first time, and finds that nearly half are unaware that the requirement to report health insurance status on their taxes takes effect this year.
