State Uninsured Rates All Over the Map

A decade after the passage of the Affordable Care Act, about one out of every five Texans under age 65 still do not have health insurance. Georgia, Oklahoma and Florida are close behind.

The contrast with Hawaii, Minnesota, Michigan, and New Hampshire is stark – only about one in 20 of their residents lacked insurance in 2018, the most recent year of available data, according to the Kaiser Family Foundation’s annual roundup of insurance coverage in the 50 states.

Despite this glaring disparity, the share of Americans lacking coverage has dropped dramatically across the board, including in Texas. Texas’ uninsured rate fell from 26 percent in 2010 to 18 percent in 2018. This translates to 2.3 million more people with health insurance. (Large populations of undocumented immigrants in states like Texas can push up the uninsured rate.)

States that had fairly broad coverage even prior to the Affordable Care Act’s (ACA) 2010 passage didn’t have as far to fall. For example, Connecticut’s uninsured rate is 6 percent, down from 10 percent in 2010.

One upshot of these two trends is that the disparity between the high- and low-coverage states has shrunk. Certainly, the strong job market gets credit for reducing the ranks of the uninsured. But millions of Americans who don’t have employer insurance have either purchased a policy on the insurance exchanges or gained coverage when their state expanded Medicaid to more low-income residents under the ACA.

For example, just two years after Louisiana’s 2016 Medicaid expansion, the uninsured rate had fallen from 12 percent to 9 percent.

But the initial benefits of the ACA seem to have played out. The U.S. uninsured rate increased slightly, from 10 percent to 10.4 percent between 2016 and 2018.

The share of people who are underinsured is also rising, the Commonwealth Fund found in a recent analysis. …
