Fewer than 1 million new customers nationwide will have health insurance from the Obamacare exchanges next year, according to a federal report published Thursday.

The Department of Health and Human Services estimates that 10 million people will be covered by private health insurance policies obtained via the Affordable Care Act’s exchange marketplaces in 2016, an increase of just 900,000 from the 9.1 million people the department estimates will have such plans by the end of this year.
