KFF’s policy research provides facts and analysis on a wide range of policy issues and public programs.

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.
Enrollment in Affordable Care Act (ACA) Marketplace health plans reached a record 24.3 million people, more than double the total in 2020, with most of the growth occurring in states won by President Trump in the 2024 election, a new KFF analysis finds.
In his latest column, president and CEO Drew Altman discusses why debate about extending the ACA enhanced tax credits set to expire this year has been slow to develop, and why it could matter to Republicans politically if the tax credits are not extended.
This chart examines individual market enrollment data from 2011 through 2025, when enrollment reached a record high of 25.2 million people. Affordable Care Act (ACA) Marketplace enrollment increased following the enactment of enhanced premium tax credits in 2021, as more individuals became eligible for subsidies.
This analysis estimates that 5.1 million people fall into the Affordable Care Act's "family glitch," which occurs when a worker receives an offer of affordable employer coverage for themselves but not for their dependents, making them ineligible for financial assistance for marketplace coverage. It explores the demographic characteristics of this group, including state-level estimates.
The House COVID-19 relief proposal would temporarily lower what millions of Marketplace enrollees and uninsured potential enrollees would pay toward premiums and would provide states that have not expanded their Medicaid programs a financial boost that would more than offset their costs initially, two new KFF analyses find.
This data note estimates how tax credits premiums will change for people at various ages and incomes under the temporary boost in subsidies included in the American Rescue Plan Act of 2021, the COVID-19 relief plan signed into law in March 2021.
The Health Insurance Marketplace Calculator, updated with 2021 premium data, provides estimates of health insurance premiums and subsidies for people purchasing insurance on their own in health insurance exchanges (or “Marketplaces”) created by the Affordable Care Act (ACA). With this calculator, you can enter your income, age, and family size to estimate your eligibility for subsidies and how much you could spend on health insurance.
As open enrollment begins for Marketplace plans, this Policy Watch provides information about consumer experiences with Marketplace sign up from the 2023 KFF Consumer Survey. Data from the survey show that Marketplace sign up has been a challenge to many consumers---often more complicated than enrollment in other kinds of health insurance. The Policy Watch also spotlights efforts to address common enrollment problems such as option overload and transitioning to Marketplace coverage from other forms of coverage.
About 5 million uninsured people across the country could get coverage through an Affordable Care Act Marketplace health plan with virtually no monthly premium if they enroll soon, a new KFF analysis finds. In most states, open enrollment runs through January 15, with tax credits available to help eligible low- and middle-income people afford coverage.
The latest Kaiser Health Tracking Poll finds that when told that the U.S. Supreme Court ruled to keep the Affordable Care Act (ACA) as it is, allowing subsidies to be provided to low- and moderate-income people in all states regardless of who runs their Marketplace, about 6 in 10 say they approve of the decision while about a third disapprove. The King v. Burwell ruling does not appear to have had an immediate effect on the public’s overall views of the health law. Still, most Americans do not think the ACA has cleared its last big hurdle with the June 25 Supreme Court ruling; just 18 percent think the King v. Burwell case was the last major battle over the ACA, while nearly 8 in 10 think there will be more to come.
