According to data from the U.S. Census Bureau’s 2015 SmallArea Health Insurance Estimates, the estimated uninsured ratefor adults under age 65 decreased in 71.3 percent of the nation’scounties (2,239 counties; there are 3,142 counties in the U.S.altogether) during that period.

And according to a 2015 report that describes demographic andeconomic differences in health insurance status across states andcounties, as well as trends in health insurance coverage, thedownward movement of lack of coverage isn’t an isolatedinstance.

Between 2013 and 2014, for the under-65 population, theestimated uninsured rate decreased in 74.1 percent of all U.S.counties (2,325 counties). And the SAHIE program estimates that,since 2013, there was an overall decrease in the uninsured rate in96.9 percent of counties (3,041 counties).

Counties in states that expanded their Medicaid eligibility sawgreater changes than those in states that did not, the reportfinds, and changes in county-level estimated uninsured rates weremost prevalent among working-age adults. Among those working-ageadults aged 18–64, the estimated uninsured rate fell in 67.6percent of all counties (2,124 counties), and for children underage 19, the estimated uninsured rate fell in 14.2 percent of allcounties (445 counties).

Interestingly, in the wake of the failure of passage of theAmerican Health Care Act, additional states are moving to expandMedicaid eligibility. The Huffington Post reports the Republican-led Kansas Senate passedan expansion bill; last month the Republican-led House did thesame, although its eventual fate is uncertain since Sam Brownback,the state’s Republican governor, opposes it.

And in Virginia, Democratic Governor Terry McAuliffe announcedearlier this week that he will once again approach the state’slegislature to approve expansion. The report cites Diane Rowland,executive vice president of the Henry J. Kaiser Family Foundation,saying that even Republican governors and state legislators couldend up following his lead.

In the report, Rowland says, “There is now a motivation to manyof those states who were on the fence to take [the expansionfunding]. They could cover a lot of low-income people with a lot offederal money.”

And Georgia’s Republican governor, Nathan Deal, has said that inthe wake of the failure to repeal the Affordable Care Act, he mayconsider Medicaid expansion as well.
