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.
In his latest column, KFF’s President and CEO Dr. Drew Altman looks at why the issue of extending the enhanced ACA tax credits has languished in Congress without clear direction, despite its importance to the 24 million people who get their coverage in the ACA Marketplaces today and the potentially significant role the issue could play in the midterms if the credits are not extended.
This analysis apportions the increase in the number of uninsured across the 50 states and DC. CBO estimates that the reconciliation law will increase the number of uninsured by 10M in 2034 and rise to over 14M if enhanced premium tax credits for ACA Marketplace enrollees expire later this year.

This brief provides an overview of the most recent ACA case under review at the Supreme Court (Kennedy v. Braidwood Management) and discusses the implications of the potential rulings by the high court.
This brief explains the preventive services coverage requirements, the basis of the Braidwood Management Inc. v. Becerra lawsuit, next steps in the litigation, and the potential implications.
In this July 1 column for The New York Times Opinion section, KFF Executive Vice President for Health Policy Larry Levitt explains how the budget reconciliation bill passed by the Senate on July 1 is effectively a partial repeal of the Affordable Care Act (ACA) and, if signed into law, the resulting reductions in Medicaid and ACA Marketplace coverage would make it "the biggest rollback in federal support for health coverage ever."
On June 27, 2025, the U.S. Supreme Court issued its opinion on Kennedy v. Braidwood Management, ruling that the ACA requirement that most private insurers and Medicaid expansion programs cover preventive services recommended by the United States Preventive Services Task Force (USPSTF) with no cost-sharing is constitutional.
This brief uses 2021 Medicaid claims data to examine utilization among Medicaid expansion adults and estimate how much cost sharing these enrollees could be required to pay under the new requirement if all states imposed the maximum cost sharing amounts. This is an illustrative analysis intended to describe which enrollees may be subject to the most cost sharing under the new provisions rather than estimate exactly what expansion enrollees may actually pay.
