You may have heard that 7.5 million Americans have used the Health Insurance Marketplace to gain coverage through its first open enrollment period. On April 16 research released by Gallup brought more good news: Fewer American adults are uninsured than before.

According to the poll, rates among adults aged 18 and older declined 2.5 percent in 21 states plus and Washington, D.C., that have implemented both Medicaid expansion and state-run exchanges, while rates dropped by 0.8 percent across 29 states that have taken one or neither of these actions.

“We feel pretty comfortable attributing much of this change to the Affordable Care Act,” lead researcher of the survey Dan Witters told NBC News.

The survey, based on interviews with 4,829 Americans without health insurance from Jan. 2-April 3, 2014, produced numerous data, including:

  • the  percentage of the U.S. population lacking health insurance has declined from an all-time high of 18 percent in late 2013 to just 15.6 percent in March;
  • an estimated 7.26 million people are insured who weren’t in September 2013; and
  • uninsured rates dropped most among lower-income and black Americans.
