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 2024, the overall uninsured rate increased for the first time since 2019 as pandemic-era continuous enrollment in Medicaid came to an end, with significant increases among Hispanic, Black, and White people under age 65. These coverage losses were largely driven by the expiration of policies to stabilize and expand access to affordable coverage that were implemented during the COVID-19 pandemic.
This policy watch provides a short overview of the Department of Health and Human Services (HHS), describing its history, budget, organizational structure and its major programs and responsibilities.

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."
This paper presents data on Medicaid spending during the years leading up to the implementation of the Affordable Care Act (ACA). It uses administrative data to first examine overall spending trends and trends by service type. We then draw on additional data to analyze per enrollee spending growth during this period, both by service type and by eligibility group, to understand what drove Medicaid spending.
