States that have embraced Obamacare continue to see a bigger drop in their uninsured population compared to those states that have not, according to a Gallup poll released Tuesday.
Gallup found that the 10 states where the uninsured rate dropped the most had each expanded Medicaid under the law and had some kind of involvement with the insurance exchange in their state. Arkansas led the pack with a 10.1 percent drop in its uninsured rate from 2013 to midyear 2014, followed by Kentucky (8.5 percent) and Delaware (7.2 percent).
Overall, the uninsured rate in states that both expanded Medicaid and participated in setting up their exchange saw a 4 percentage point drop in their uninsured rate (16.1 percent to 2.1 percent) compared to a 2.2 percentage point drop in states that did one or neither of those things (18.7 percent to 16.5).
The 2013 figures are based on a yearlong survey of 178,068 adults. The midyear 2014 figures are based on surveys from Jan. 2 to June 30 of 88,678 adults.
