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.
The interactive map shows the increase in states with laws restricting abortion coverage in Medicaid and private insurance in 2010 compared to the present.
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 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.
To understand the impact of Medicaid work requirements included in the budget reconciliation bill being debated in Congress, KFF has undertaken two different analyses using different data sources. Using 2023 data from the Survey of Income and Program Participation, this analysis looks at the share of adults who work at least 80 hours per month, the reasons some do not, and how consistently individuals meet the requirement over a six-month period.
This brief looks at changes to Marketplace plans recently finalized by the Centers for Medicare and Medicaid Services (CMS) that may incentivize insurers to make their plans less generous. With less generous plans, consumers could face higher out-of-pocket costs, though those who don't qualify for premium tax credits could see lower premiums.
This analysis details the number of people who would become uninsured from policy changes in the ACA Marketplaces and Medicaid. The Congressional Budget Office estimates that, taken together, these changes will result in 16 million more uninsured people in the year 2034 than would otherwise be the case.
This analysis examines the potential impacts of a provision in the House reconciliation bill that proposes reducing the federal matching rate for the Affordable Care Act (ACA) Medicaid expansion population from 90% to 80% for states that either provide health coverage or financial assistance to purchase health coverage to individuals who are not “a qualified alien.”
This issue brief presents KFF WHS data on access to mental health services among women and men ages 18 to 64, and it also takes a closer look at mental health coverage among women.
This issue brief provides an overview of the potential impact not extending enhanced ACA premium tax credits could have on people with HIV and the Ryan White HIV/AIDS Program. Enhanced credits have improved insurance coverage affordability for millions of people, including those with HIV. People with HIV may be particularly vulnerable, given that they are more likely to have Marketplace plans and many also rely on the federally-funded Ryan White HIV/AIDS Program to help cover plan costs. Loss of coverage and increased costs could lead to disruptions in care for people with HIV which could have serious implications for individual and public health.
