During the first quarter of 2015, seven million more people had health insurance compared with the same time period last year, according to a Centers for Disease Control and Prevention (CDC) report.
Overall, 29 million people in the U.S. (9.2 percent of the population) did not have health insurance in the first three months of 2015. In 2014, 36 million people (11.5 percent of the population) were uninsured.
Among adults 18 to 64, the uninsurance rate fell from 16.3 percent in 2014 to 13 percent this year. During that same time period, the percentage of adults with private insurance increased from 52.6 percent in 2014 to 56.3 percent this year.
Meanwhile, 9.7 million adults under 65 purchased coverage through the federal government or state-based exchanges during the first three months of 2015, up from 6.7 million in the last three months of 2014.
The CDC report was based on interviews with 26,121 people from January to March 2015.
Before the 2010 passage of the Patient Protection and Affordable Care Act, 22.3 percent of adults from 18 to 64 were uninsured, according to the CDC.
