America's uninsured rate plummeted last year, with the improvement driven by states that have fully implemented the Affordable Care Act, a new nationwide Gallup survey indicates. Led by Arkansas and Kentucky, which both had double-digit declines, seven states saw the percentage of adults without insurance fall by more than 5 percentage points between 2013 and 2014.

The share of Americans without health insurance dropped to its lowest level in seven years in 2014 as President Barack Obama's overhaul took full effect, according to an extensive survey released Tuesday. The Gallup-Healthways Well-Being Index found that the trend appears likely to continue this year, since 55 percent of those who remained uninsured told the pollster they plan to get coverage rather than face escalating tax penalties.
