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.
State Health Facts is a KFF project that provides free, up-to-date, and easy-to-use health data for all 50 states, the District of Columbia, and the United States. It offers data on specific types of health insurance coverage, including employer-sponsored, Medicaid, Medicare, as well as people who are uninsured by demographic characteristics, including age, race/ethnicity, work status, gender, and income. There are also data on health insurance status for a state's population overall and broken down by age, gender, and income.
This Health Policy 101 chapter explores the performance of the U.S. health system on a number of cost, outcomes, and quality measures by comparing it with those in similarly large and wealthy OECD nations. It highlights that despite significant spending, Americans have shorter life expectancies and encounter more barriers to health care, influenced by both the health system's structure and broader socioeconomic factors.
This Health Policy 101 chapter provides an overview of the Affordable Care Act (ACA), a major reform of the U.S. health care system aimed at reducing high uninsured rates and alleviating issues like high out-of-pocket costs and coverage exclusions for preexisting conditions. The ACA significantly altered many aspects of the health system and the chapter explores its mechanisms, such as the Health Insurance Marketplaces, and the evolution of the law since its passage in 2010 to the changes in the 2025 budget reconciliation law.
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. Economic conditions, federal and state policy decisions, and major health crises like the COVID-19 pandemic influence the uninsured rate. While implementation of the Affordable Care Act, namely the expansion of Medicaid and availability of subsidized Marketplace coverage, led to a drop in the share of people who are uninsured, disparities in coverage persist and policy changes in the 2025 budget reconciliation bill are expected to increase the size of the population.
This issue brief describes the hardship exception for individuals living in counties with high unemployment, and using the most recent available county-level unemployment data, estimates the number of counties that could meet the criteria for this exception and the number of expansion enrollees living in those counties who could be exempt from work requirements.
This policy watch outlines the groups of lawfully present immigrants that will lose access to federally funded health coverage due to the 2025 tax and budget law, and the CBO’s estimates of the increases in the uninsured.
This issue brief describes the impact of H.R.1's 10-year delay in implementing provisions in two Medicaid eligibility rules that would have reduced red tape. The delayed rules are projected to decrease federal spending and future Medicaid and CHIP enrollment and increase coverage loss.
This brief examines key characteristics of part-time workers and their access to coverage. Part-time workers are much less likely than full time ones to be offered health benefits by their employer or to have health coverage at all.
In his latest column for the JAMA Health Forum, KFF’s Larry Levitt talks about how popular shows like “The Pitt” can make changes to the health care system stemming from this year’s federal tax and budget bill tangible for viewers, and offers some suggested story lines.
The ACA enhanced premium tax credit has driven growth in Marketplace enrollment and offset declines in Medicaid coverage, holding 2024's 8% uninsured rate at its near-historic low, according to new Census Bureau data.
This analysis estimates that 48% of adults under age 65 with individual market coverage are either employed by a small business with fewer than 25 workers, self-employed entrepreneurs, or small business owners. Because the vast majority of this coverage is purchased through the Affordable Care Act (ACA) Marketplaces, changes to the ACA, including the expiration of the enhanced premium tax credits at the end of this year, would have significant implications for what small business owners and workers spend on their health care.
