The United States is the only industrialized country in the world without universal health care — and as a result, most Americans under age 65 receive employer-based health insurance coverage. Under this system, an estimated 28.9 million Americans under age 65 were uninsured in 2019 — before over 22 million Americans lost their jobs in the early months of the COVID-19 pandemic.
While most of those jobs have since been restored, the official uninsured rate for Americans younger than 65 in 2020 will likely be higher than the 10.3% rate in 2019 — a continuation of the three-year trend of declining insurance coverage that began in 2017. Still, there are many parts of the country where nearly every American under 65 is insured, either through their employer, Medicaid, or directly purchased coverage.
Using data from the U.S. Census Bureau, 24/7 Wall St. identified the 50 counties with the best health insurance coverage. Counties are ranked on the share of residents under age 65 — the age of eligibility for Medicare — who are uninsured.
The counties on this list span 15 states, primarily in the Midwest and Northeast. Over half of the 14 counties in Massachusetts rank on this list largely because the state was a national leader in health care reform, enacting laws that led to near-universal coverage almost half a decade before the Affordable Care Act was signed into law under the Obama Administration.

Methodology:
To determine the counties with the best 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.
