The percentage of U.S. adults ages 18 to 64 who were uninsured rose rapidly between 2009 and 2010 because of a drop in the private plan participation rate.
Researchers at the U.S. Centers for Disease Control and Prevention (CDC) have published those figures in a release of data gathered through the National Health Interview Survey.
The CDC based the survey report on interviews with 89,665 U.S. residents.
Almost all legal U.S. residents ages 65 and older have health coverage through Medicare.
The researchers found that the United States has had better success with providing health coverage for children than for adults ages 18 to 64.
Only 7.8% of the survey participants’ children were uninsured at the time of the interview, compared with 22% of the adults ages 18 to 64.
The uninsured rate for children fell to 7.8% in 2010, from 8.2% in 2009.
The overall uninsured rate for adults ages 18 to 64 increased to 22.3%, from 21.1%.
