The percentage of uninsured people in the U.S. dropped below 10% this year for the first time, according to a Centers for Disease Control and Prevention survey released Wednesday.
The national uninsured rate decreased to 9.2% in the first three months of 2015 from 11.5% a year earlier as 7 million people gained insurance, according to the survey, conducted by the CDC's National Center for Health Statistics.
The reduction is not as big as the drop from 2013 to 2014, when 8.8 million people gained coverage. The total decrease since major parts of the Affordable Care Act went into effect in 2013 is 15.8 million.
More people have gotten covered in states that expanded Medicaid under the law and in states that set up their own exchanges instead of relying on an exchange created for them by the federal government, according to the report.
Still, 28% of the nation's poor remain uninsured, and Hispanics were significantly more likely to lack insurance—28.3%, compared with 15.6% of non-Hispanic blacks, 8.7% of Asians and 7.2% of non-Hispanic whites.
The survey data is based on interviews with more than 26,000 people.
