The Uninsured Population and Health Coverage

This Health Policy 101 chapter examines the share of the United States population who are uninsured, highlighting their demographics and the challenges they face because of the lack of coverage.

How Many Uninsured Are in the Coverage Gap?

This analysis estimates that 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 tax credits that would make coverage ACA's Marketplaces affordable to them.

Key Facts about the Uninsured Population

The number of people ages 0-64 who were uninsured held steady at 25.3 million in 2023, although the number of uninsured children rose from 3.8 million to 4.0 million. Most uninsured people are in low-income families and have at least one worker in the family.

How the Unwinding Affected Enrollees

Over half who were disenrolled say they put off needed medical care while trying to renew Medicaid. Overall, 19% of adults who had Medicaid prior to the start of unwinding say they were disenrolled at some point in the past year. Of this group, a large majority (70%) were left at least temporarily uninsured.

    Feature

    The ACA’s third open enrollment will come to a close at the end of January and the December Kaiser Health Tracking Poll finds that only 7 percent of the uninsured correctly identify this as the deadline to enroll in coverage. With Democratic presidential candidates debating the idea of Medicare-for-all, which involves creating a national health plan in which all Americans would get their insurance through an expanded version of the Medicare program, most Democrats like the idea, but very few say the issue will drive their votes in the 2016 elections.

In addition, the public remains divided over what Congress should do next with the law, with 35 percent supporting repeal, 14 percent supporting scaling back the law, 18 percent who say they would like to see it implemented as is, and 22 percent who say they want the law expanded.
