Public Opinion and Survey Research

This poll looks at awareness and concern over the outbreak of measles in the U.S. and finds that a growing share of adults is encountering false claims about the measles vaccines, but many are uncertain whether these claims are true or false. Parents who lean toward believing the false claims are less likely to say they keep their children up to date on routine vaccinations.

As bird flu continues to spread among animals in the U.S., KFF’s Tracking Poll on Health Information and Trust finds that the public is more concerned about its impact on food prices than potential health impacts. Trust in the CDC to provide information on bird flu is also divided along partisan lines, and a large share of the public is uncertain about public health agencies’ recommendations for preventing infection.

Amid discussion of changes to the Medicaid program, most of the public say that Medicaid is important to their local communities. About two in ten favor cuts to Medicaid spending. Support for Medicaid cuts remain low even among typically conservative groups such as Republicans, Trump voters, and those living in rural communities. The poll also gauges the impact of arguments for and against Medicaid work requirements and reductions to federal spending on ACA expansion.

This poll finds most of the public believe the cutbacks at USAID will lead to increases in illness and death in low-income countries. Nearly half say it will reduce the U.S. budget. Most of the public also overestimates the share of the federal budget that is spent on foreign aid, and when informed it is about 1% of the federal budget, the share who want to reduce spending drops.

KFF’s January 2025 Prescription Drug Advertisements Poll looks at the public’s experiences with prescription drug advertisements, whether they’ve talked to a doctor about advertised drugs, and how this has influenced the care they receive.

As Senate hearings begin for President Trump’s health nominees, including Robert F. Kennedy Jr., the latest KFF Tracking Poll on Health Information and Trust shows a decline in public trust for government health agencies like the CDC, FDA, and local public health officials. The poll reveals growing skepticism about vaccines and school vaccine requirements, especially among Republicans and parents, while misinformation about vaccine safety persists. Despite low concern about the H5N1 bird flu, the U.S. public is divided on how prepared they believe the government is for future health crises or pandemic.

With the incoming Trump administration and Republican-led Congress looking to ways to reduce federal spending, this Poll finds that the Medicare and Medicaid programs remain broadly popular, and more people favor more spending on those programs than less spending. Among potential actions on health, the public sees price transparency and limiting chemicals in food as top priorities. Few say so about cuts to Medicaid and restrictions on abortion.

A new issue brief based on focus groups conducted by KFF among NHPI adults living in Hawaii and the continental U.S. highlights barriers NHPI people face when accessing health care, including geographic isolation, limited system capacity, and language access. In their own words, participants describe both positive and negative experiences in health care settings and discuss concerns about mental health in their communities.

KFF’s analysis of KFF/AP VoteCast supplemental questions shows how abortion, abortion-related ballot measures, and other health care issues influenced the 2024 election.

In a resurvey of women voters three months later, KFF uncovered substantial shifts in favor of Vice President Harris across a range of key election issues, including the handling of rising household and health care costs as well as enthusiasm for the candidates and motivation to vote. As the presidential election draws near, the survey also showed a pronounced rise in the salience of abortion for women under 30.
