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.
Following the Trump administration’s warning last month that using acetaminophen – the active ingredient in Tylenol – during pregnancy can increase the risk of autism in children, very few adults say the claim about a causal relationship is “definitely true,” though much of the public is uncertain whether to believe it. Trust in the CDC to provide reliable vaccine information has fallen to a new low.
A look at public opinion about the ACA and its provisions, including protections for people with pre-existing conditions and the impact of the law on families.
KFF's Health Tracking Poll finds that more than three-quarters of the public say they want Congress to extend the ACA enhanced premium tax credits that are set to expire at the end of this year. If the credits do expire and the average premium more than doubles, seven in 10 of those who purchase their own insurance say they would not be able to afford premiums without significantly disrupting their household finances.
The Survey of 1988 NFL players, conducted by KFF in partnership with ESPN, looks at the overall health and well-being of former professional football players who played in the 1988 NFL season. While many are grappling with the immense toll the sport has taken on their physical and neurological health, most say they would do it all over again.
KFF's Tracking Poll on Health Information and Trust finds that just over half of adults use social media for health information and advice at least occasionally but fewer than half say they find “most” or “some” of the information they see on each platform trustworthy.
As federal vaccine policy changes, this poll finds that most adults do not expect to get a COVID-19 vaccine this fall , and many parents are confused and uncertain about whether the vaccine is recommended for healthy children this year. About one in five adults nationally say the changes to vaccine policy are making people safer, while more than a third say they are making people less safe.
Following a pledge by insurance companies to reduce the burden of prior authorizations, KFF's Health Tracking Poll examines the publics experience with the process. The poll finds that most view insurers' delays and denials as a problem, and few are aware of the newly announced pledge.
KFF's Health Tracking Poll looks at awareness and perceived impact of the tax and budget law signed by Trump in July 2025. Nearly half of the public says that they expect the new law to generally hurt them and their families, about twice the share who say it will generally help. The law itself remains largely unpopular, with many more people holding unfavorable views than favorable ones.
KFF's Health Tracking Poll looks at public awareness and support for ACA Marketplace subsidies and finds that most adults are unaware the subsidies are set to expire soon. Three in four say Congress should extend the subsidies and support persists despite hearing counter arguments.
This poll finds two-thirds of the public view the "One Big Beautiful Bill" legislation unfavorably, and its favorability erodes further when people hear about its potential health impacts. As Congress debates changes to Medicaid and the ACA as part of the bill, each program's popularity is at a record high.
