One in three say they would be “very likely” to look for a lower-premium Marketplace plan.

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.

  • Kaiser Health Tracking Poll: January 2014

    Feature

    With enrollment in new coverage options underway, a majority of the public believes that only “some” of the ACA’s provisions have been put into place, while just about one in five think “most” or “all” of the law has been implemented. Awareness of the law’s individual mandate and health insurance exchanges has increased slightly since last year, but about four in ten of the public overall and half the uninsured remain unaware of other major provisions. For the third month in a row, overall views of the law remain at their post-rollout more negative levels (50 percent unfavorable, 34 percent favorable), though over half the public – including three in ten of those who view the law unfavorably – say opponents should work on improving the law rather than keeping up efforts to repeal it.

  • Kaiser Health Tracking Poll: January 2015

    Feature

    The latest Kaiser Health Tracking Poll finds though few Americans are paying attention to the pending Supreme Court case over whether the health care law says that people in all states can get financial help to buy health insurance, most say they would want Congress and their state to act to fix potential gaps should the Supreme Court rule in favor of the plaintiffs.
