After initial dive, uninsured rate levels out

The U.S. uninsured rate has leveled out, after taking an initial dive under provisions of the Affordable Care Act, new government data show.

About 28 million Americans were uninsured during the first six months of the year, or 8.9 percent, unchanged from the first half of 2015, according to a report released Thursday by the Centers for Disease Control and Prevention's National Center for Health Statistics.

The uninsured population was much bigger six years ago, as President Obama's healthcare law was being passed. In 2010, about 48 million Americans lacked health insurance. That population plummeted as the law's marketplaces opened in 2014 and states expanded their Medicaid programs, folding most of them into government-sponsored plans or private plans subsidized with taxpayer dollars.

The uninsured rate is now at its lowest ever, around 9 percent, a fact the Obama administration frequently notes.
