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.

A core issue in the entitlement and health reform debates is the problem of rising health care costs. President Obama, now apparently fully briefed on the economic, budget and health reform realities he faces, is talking conspicuously about hard choices that may lie ahead.

  • Putting Children on the Express Lane to Health Insurance: Streamlining Enrollment and Renewal of Children in Medicaid and CHIP Through Express Lane Eligibility

    Issue Brief

    Express Lane Eligibility (ELE) is a new tool available to states to streamline enrollment and renewal of children in Medicaid and CHIP. It allows state Medicaid and CHIP agencies to utilize data and eligibility findings from other public need-based programs, such as Head Start or Food Stamps, and/or tax return data to identify, enroll and recertify children rather than requiring them to re-analyze and determine eligibility under their own rules. A primary goal of this…
