When President Barack Obama signed the Affordable Care Act in 2010, about 48.6 million people lacked health insurance in the U.S. In the first half of 2018, 28.5 million lacked insurance – a decrease of 20.1 million, the Centers for Disease Control and Prevention said Thursday.
The uninsured rate for the first half of 2018 was 8.8 percent, not significantly different from the 2017 rate of 9.1 percent, the CDC said, and overall, the percentage of people without insurance appears to be stabilizing.
Not all states are the same, however, with states that expanded Medicaid under the ACA showing significantly lower uninsured rates. In expansion states, 9.1 percent of adults lacked coverage in the first six months of 2018, while 18.1 percent of adults were uninsured in non-expansion states.
