2025 KFF Marketplace Enrollees Survey

In 2025, about one in three ACA enrollees said they would be “very likely” to look for a lower-premium Marketplace plan If their premium payments doubled.

Following the expiration of the enhanced premium tax credits for people with Affordable Care Act (ACA) Marketplace plans, a new KFF follow-up survey of the same Marketplace enrollees KFF surveyed in 2025 finds half (51%) of returning enrollees say their health care costs are “a lot higher” this year compared to last year, including four in 10 who specifically say their premiums are “a lot higher.”

  • Pulling it Together: Business and Health Care Costs

    Perspective

    Hidden away on page 218 of our annual Employer Health Benefits Survey is a table that shows what employers think of the main strategies they have to control health care costs.  More specifically, the table shows what the person in the firm responsible for its health benefits thinks, which is whom we survey.  The short answer is, employer confidence in their own ability to control costs is not high. Not more than about a quarter…

  • Kaiser Health Tracking Poll — August 2011

    Feature

    The August tracking poll examines the views of Americans without health insurance, with a particular focus on how they think the health reform law will affect them. Findings from the poll include: Although estimates are that 32 million uninsured Americans will gain coverage under the ACA, only about half of non-elderly Americans currently without coverage say they are familiar with the chief components in the law designed to achieve this goal. Perhaps because awareness of…

  • Pulling it Together: 19.7

    Perspective

    Several years ago Joanne Silberner from NPR offered some advice I liked. Joanne said that the secret to effective communication was to "have a killer anecdote and a killer number." Here is a killer number: 19.7. That's the average number of years between major attempts at health reform since Harry Truman made health reform a top priority and his plan was branded a socialist plot and soundly defeated in 1950. The chart below chronicles the…

  • Pulling it Together: What Will Health Reform Do For Me?

    Perspective

    There is one poll number that may be more important to watch than any other if we have a big debate about health reform: The percentage of Americans who think that they or their families would be better off if the president and the Congress enacted major health reform legislation. It's a number that signals whether people think that health reform legislation will actually help them with the problems they are having in the current…

  • Pulling It Together: Keeping the Health Reform Coalition Together

    Perspective

    We could be headed for a new schism in the debate about health reform. Not the familiar gulf between advocates of the market and government, or the predictable one between deficit hawks and spenders, but a new one that crosses traditional partisan and ideological lines between advocates of long-term reform of the health care delivery system, and immediate help for the uninsured and insured struggling with health care costs.  This new rift is most likely to develop if tight money and a crowded agenda…

  • Kaiser Health Tracking Poll — February 2012

    Feature

    In the midst of continuing debate on the future of the Medicare program, the February Kaiser Family Foundation Tracking Poll finds most Americans and most seniors favor the status quo, though arguments about the program’s solvency have the potential to sway opinion toward new proposals. The survey also gauges public opinion about the ongoing contraceptive coverage debate, views of the Affordable Care Act, and trust in the presidential candidates on health care issues. The February…

  • The Digital Divide And Access To Health Information Online

    Poll Finding

    The Affordable Care Act (ACA) calls for a number of web-based initiatives, including development of the website healthcare.gov which provides a variety of health information and helps individuals find coverage options. Therefore, understanding the level and quality of Internet access among those groups most likely to benefit from reform, such as the uninsured, those with lower incomes, and members of racial and ethnic minority groups, is an important consideration as health reform is implemented. A…

  • Kaiser Health Tracking Poll — February 2011

    Feature

    In the wake of the health reform repeal vote in the U.S. House and the ongoing legal challenges over the individual mandate, nearly half the country either believes that the Patient Protection and Affordable Care Act (ACA) has been repealed and is no longer law (22 percent) or doesn’t know enough to say whether it is still law (26 percent). Roughly half of Americans (52 percent) accurately report that the ACA is still the law…
