THURSDAY, June 19, 2014 (HealthDay News) -- Two new U.S. government reports provide a statistical snapshot of health and health insurance coverage in 2013, before new coverage options took effect under the Affordable Care Act.
On a positive note, fewer Americans were uninsured in 2013 than in 2010 -- 14.4 percent versus 16 percent, respectively.
But sharp coverage gaps remained depending on factors like age, race or ethnicity and where people live.
The reports, released Thursday by the U.S. National Center for Health Statistics (NCHS), draw on data from interviews with more than 104,000 families as part of the 2013 National Health Interview Survey. Estimates for 2013 were compared with prior periods going back as far as 1997.
"I think what this gives us is a great baseline," said Shana Lavarreda, director of health insurance studies at the University of California, Los Angeles' Center for Health Policy Research. She was not involved with the studies.
Researchers will use the data to evaluate changes between 2013 and 2014, when millions of previously uninsured Americans will have gained coverage through the Affordable Care Act, also known as Obamacare.
Another 4.8 million enrolled in Medicaid and the Children's Health Insurance Program. And an estimated 5 million people selected health plans sold outside of the new state and federal marketplaces, HHS said.
Because new marketplace options and expanded state Medicaid coverage took effect this year, the increase in coverage was not reflected in the 2013 data.
In 2013, 20.4 percent of people aged 18 to 64 -- the health-reform law's target population -- were uninsured for at least part of the year. They were twice as likely to experience a lack of coverage as children.
Hispanic people were three times as likely, and blacks were more than 1.5 times as likely, to be uninsured as whites, researchers found.
