The independent source for health policy research, polling, and news.
KFF’s policy research provides facts and analysis on a wide range of policy issues and public programs.
KFF designs, conducts and analyzes original public opinion and survey research on Americans’ attitudes, knowledge, and experiences with the health care system to help amplify the public’s voice in major national debates.
KFF Health News is a national newsroom that produces in-depth journalism about health issues and is one of the organization’s core operating programs.
Health Policy 101 is a comprehensive guide covering fundamental aspects of U.S. health policy and programs, including Medicare, Medicaid, the Affordable Care Act, employer-sponsored insurance, the uninsured population, health care costs and affordability, women's health issues, and health care politics. The Health Care Costs and Affordability chapter explores trends in health care costs in the U.S. and the factors that contribute to this spending. It also examines how health care spending varies across the population, the impact of costs on care affordability and individuals' overall financial vulnerability.
Ahead of the 2026 midterm elections, this KFF issue brief examines the role health care has played in previous elections and what that may suggest about its potential role in 2026. KFF polls have consistently found that the cost of health care is an important part of voters’ economic concerns.
This KFF survey is a follow-up survey of adults who had ACA Marketplace insurance in 2025. The survey examines the cost concerns and coverage changes that these 2025 Marketplace enrollees are experiencing following the expiration of the enhanced premium tax credits. The survey finds that half of returning enrollees say their health care costs are “a lot higher” and most expect to cut back on basic household expenses to afford coverage.
This data note reviews our recent polling data that finds that many Americans struggle to afford many aspects of health care, including disproportionate shares of uninsured adults, Black and Hispanic adults and those with lower incomes.
As the 2026 midterms approach, health care costs remain voters' top health priority, but fraud in government health programs, including Medicaid and Medicare, is resonating with Republican voters, 55% of whom say it's extremely important for candidates to address. Most voters say there is at least “some” fraud in government health programs, but larger shares say there is fraud in the tax system, defense, and foreign aid, while the smallest share sees fraud in the…
This analysis examines early indicators of how the expiration of enhanced premium tax credits has affected effectuated enrollment levels (i.e., enrollment among people who have paid their premiums), plan selections, and out-of-pocket costs in 2026, drawing on plan selection and effectuated enrollment data from the Centers for Medicare & Medicaid Services (CMS) and state-based Marketplace (SBM) Open Enrollment reports, as well as KFF survey data and individual market enrollment estimates from Wakely Consulting Group.
This brief highlights voices from adult focus group participants with low and moderate incomes who gained Medicaid or Marketplace coverage following implementation of the ACA. It focuses on work, including work status, the new labor market, job benefits, and the role of ACA coverage for those with non-traditional jobs.
The April 2019 KFF Health Tracking Poll examines the public’s position on the future of ACA and its protections for people with pre-existing medical conditions, in light of the ongoing legal battle which may end up in the Supreme Court. With lawmakers proposing legislation to address surprise medical bills, this month’s survey also measures the public’s support for federal government action to protect patients from having to pay the cost incurred from an inadvertent out-of-network…

Juliette Cubanski, Associate Director of the Foundation's Program on Medicare Policy, testified on Feb. 27, 2013 before the Senate Special Committee on Aging to provide an overview of the Medicare program and Medicare beneficiaries' costs and service utilization. Testimony (.pdf)
To date, there has been little research providing a quantitative look at the causes of medical bill problems and the impacts they have on people’s families, their finances, and their access to health care. To fill this gap, the Kaiser Family Foundation and The New York Times conducted an in-depth survey with 1,204 adults ages 18-64 who report that they or someone in their household had problems paying or an inability to pay medical bills…
