(HealthDay News) — The percentage of uninsured persons is decreasing in the United States, according to a report published by the National Center for Health Statistics (NCHS).

Michael E. Martinez, MPH, from the NCHS in Atlanta, and colleagues estimated health insurance coverage for the civilian noninstitutionalized US population for the first 9 months of 2015 for 37 selected states, based on data from 79 847 persons.

The researchers observed a decrease in the number of uninsured persons from 2013; 28.8 million persons (9.1%) of all ages were uninsured in 2015, which was 7.2 million fewer than in 2014 (11.5%), and 16.0 million fewer than in 2013. 

The percentage of uninsured adults aged 18 to 64 years decreased from 16.3% in 2014 to 12.9% in 2015; there was a corresponding increase in private coverage, from 67.3% to 70.0%. The percentage of children aged younger than 18 years with private coverage increased from 52.6% in 2013 to 55.1% in 2015.

The percentage of those aged younger than 65 years with private coverage through the Health Insurance Marketplace or state-based exchanges increased from 2.5% in the fourth quarter of 2014 to 4.2% in the third quarter of 2015.

“This report from the NCHS presents selected estimates of health insurance coverage for the civilian noninstitutionalized US population,” the researchers wrote.
