The uninsured rate has dropped to its lowest level since Gallup began tracking the statistic in 2008.
A total of 11.4 percent of people remained uninsured in the second quarter of this year, between April and June, according to a Gallup poll released Friday.
The biggest declines were seen in the black and Hispanic communities, and among those making less than $36,000 a year, with all those groups reporting declines of nearly 10 percentage points.
The new poll marks the latest good news for the healthcare law, which has helped nearly 17 million people gain insurance since marketplaces opened in 2013.
Since the insurance marketplaces opened, the uninsured rate has plummeted from a record high of 18 percent.
So far this year, the uninsured rate dropped to 11.4 from 11.9 percent shortly after the administration’s Feb. 15 deadline to purchase health insurance.
About 10.2 million people bought plans through the federal insurance exchanges in the most recent enrollment period.
The rate is likely to again drop during next year’s sign-up period, which begins in October, though the poll notes that the decline may be less “as those who remain uninsured are likely the hardest to engage.”
