Uninsured

New and noteworthy

Quote from KFF President and CEO Drew Altman reads, "when it comes to the “affordability crisis” driving the national discussion of health care today, the chronically ill, and most of all the chronically ill uninsured, are the tip of the spear."

The Group that Struggles the Most in American Health Care

In a new column, Dr. Drew Altman, KFF’s Founding President and CEO, previews findings about the chronically ill uninsured from a large KFF survey of 25,000 Americans focusing on the cost and access challenges facing the chronically ill, which will be released tomorrow. He writes: “There are more than enough needs to go around in American health care, but if I had to pick the one group that struggles the most with costs and access, it would be people with chronic illnesses who are also uninsured.”

Key Facts about the Uninsured Population

The number and share of people without insurance grew in 2024, increasing for the first time since 2019, according to KFF’s analysis of data from the American Community Survey (ACS). This issue brief describes trends in health coverage in 2024, examines the characteristics of the uninsured population , and summarizes the access and financial implications of not having coverage.

Data and analysis

The coverage gap exists because some states did not expand Medicaid under the ACA to cover adults under age 65 without dependent children with incomes at/below 138% of the federal poverty level (FPL)

How Many Uninsured Are in the Coverage Gap?

An estimated 1.4 million uninsured individuals in the 10 states without Medicaid expansion, including many working adults, people of color, and those with disabilities, remain in the "coverage gap," ineligible for Medicaid or for ACA tax credits that would make coverage affordable.

  • The Health Reform Law’s Medicaid Expansion: A Guide to the Supreme Court Arguments

    Issue Brief

    One significant element of the pending U.S. Supreme Court case challenging the Affordable Care Act is the constitutionality of the law's Medicaid expansion. This provision of the law requires states that choose to participate in the Medicaid program to cover nearly all adults under age 65 with household incomes at or below 133% of the federal poverty level as of January 2014. A ruling on the Medicaid expansion could have far-reaching impacts on the present…

  • Optimizing Medicaid Enrollment: Perspectives on Strengthening Medicaid’s Reach Under Health Care Reform

    Issue Brief

    The health reform law creates a national plan for near-universal health coverage that relies on a large expansion of Medicaid eligibility as its foundation. This brief draws on recent interviews with Medicaid program directors and other experts about the opportunities that health reform presents to optimize Medicaid by strengthening its enrollment and renewal operations and recasting it as an affordable health coverage program for working people and families.

  • Pulling It Together: Rising Health Costs Are Not Just a Federal Budget Problem

    Perspective

    Premiums for employer-provided health insurance, where 150 million Americans get their coverage, jumped 9% in 2011 while workers’ wages grew just 2%, according to our annual employer survey.  The average family policy now costs more than $15,000 per year, more than the cost of a Chevy Aveo or a Ford Fiesta.  Since we began doing this survey thirteen years ago, worker contributions to premiums have increased 168%, wages 50%, and inflation 38%. Critics of the…

  • Small Area Variations and the ACA’s Coverage Expansions

    From Drew Altman

    A new Kaiser analysis sheds light on how the country might react to the Affordable Care Act (ACA) when it is implemented.  It looks at how the benefits of the ACA's coverage expansions will vary around the country by census areas (technically, Public Use Microdata Areas, or PUMAs).  PUMAs are artificial areas of about 100,000 people each created by the Census Bureau to provide more detailed demographic, social and economic information at the local level.  They…

  • Do State Decisions to Prioritize Renewals for Medicaid Enrollees Who are Likely Ineligible Affect Early Disenrollment Rates?

    Policy Watch

    Some states are prioritizing Medicaid renewals for enrollees flagged as likely to be ineligible. Early data from Arizona, Idaho, and Pennsylvania show disenrollment rates for flagged enrollees are higher than for other enrollees. This analysis considers why different state approaches to renewals may explain some – but not all – variation in disenrollment rates across the U.S.

  • Cost Concerns and Coverage Changes: A Follow-Up Survey of ACA Marketplace Enrollees

    Poll Finding

The survey examines the cost concerns and coverage changes that these 2025 Marketplace enrollees are experiencing following the expiration of the enhanced premium tax credits.

This slideshow provides figures and tables on the uninsured and health insurance coverage for the following subpopulations: nonelderly, children, nonelderly adults and working adults.

  • Pulling it Together: The Experts vs. The Public on Health Reform

    Perspective

    In repeated Kaiser polls, we see a divide between what experts believe and what the public believes about some of the key issues in health reform. They don’t disagree on everything; far from it. But there is a wide gulf on basic beliefs about what is behind the problems in the health care system and key elements of reform, especially delivery reform. Experts believe the health care system is full of unnecessary care and troubling…

  • Pulling It Together: The Message from Massachusetts

    Perspective

    The Massachusetts special election has roiled the political world and profoundly affected the prospects for health reform just when it looked like passage was a lock.  Efforts are underway to put health reform legislation back together again on Capitol Hill, but not since powerful Ways and Means Chair Wilbur Mills fell into the Tidal Basin with Fanne Foxe in 1974, halting momentum on a deal on health reform that seemed ready to happen, has something this unexpected so affected…
