The share of Americans under the age of 65 without health insurance fell every year between 2010, when the Affordable Care Act was signed into law, and 2016, when President Barack Obama left office. Though the uninsured rate among Americans younger than 65 has inched up over the years since, it remains well below the 17%+ figures in the years leading up to the ACA.
Without a universal health care program, employer- based health insurance covers most Americans under age 65. Under this system, 10.3% of Americans younger than 65, approximately 25 million people, lacked health insurance in 2019 — and that was before the COVID-19 pandemic put over 22 million Americans out of work.
While most of those jobs have since been restored, the official 2020 uninsured rate for Americans under 65 will likely be higher than the 2019 rate, which, in some parts of the country, was already well above the national uninsured rate levels from before the passing of the ACA.
Using data from the U.S. Census Bureau, 24/7 Wall St. identified the 50 counties and county equivalents with the worst health insurance coverage. Counties are ranked based on the share of residents under age 65 — the age of eligibility for Medicare — who are uninsured.
Half of the counties and county equivalents on this list are in Southern states — including 19 in Texas alone.

Methodology:
To determine the counties with the worst health insurance coverage in the nation, 24/7 Wall St. reviewed five-year estimates of the percentage of the noninstitutionalized civilian population under 65 without health insurance from the U.S. Census Bureau’s 2019 American Community Survey.
Of the 3,220 counties or county equivalents, 3,142 had boundaries that fell within one of the 50 states or the District of Columbia.
Counties were excluded if the noninstitutionalized civilian population under 65 was less than 1,000, or if the sampling error associated with a county’s data was deemed too high.
The sampling error was defined as too high if the coefficient of variation — a statistical assessment of how reliable an estimate is — for a county’s under 65 uninsured rate was above 15% and greater than two standard deviations above the mean CV for all counties’ under 65 uninsured rates. We similarly excluded counties that had a sampling error too high for their under 65 noninstitutionalized civilian population, using the same definition.
We selected the under 65 age group because Americans become eligible for Medicare at age 65, and the uninsured rate for the population above this age is less than 1% nationwide. However, because the census doesn’t publish insurance coverage estimates specifically for the under 65 age group, we aggregated the data from more granular age breakdowns.
To ensure each aggregate estimate’s sampling error could be assessed using the definition above, we derived a margin of error for each aggregate estimate using the successive differences replication variance estimation methodology recommended and used by the U.S. Census Bureau.
The remaining 2,946 places were ranked based on their under 65 uninsured rates. To break ties, we used the number of insured people in the same population group.
The shares of the population covered by each type of insurance — Medicare, Medicaid, VA, employer, direct-purchase, and Tricare/military — are for the same cohort and are also aggregated from five-year ACS estimates. The estimates reflect people who are covered by that type of insurance alone or in combination with other types on the list. So, when a person is covered by more than one type of insurance, they are included in each group.
