"The uninsured rate has been falling since the fourth quarter of 2013, after hitting an all-time high of 18.0% in the third quarter -- a sign that the Affordable Care Act, commonly referred to as 'Obamacare,' appears to be accomplishing its goal of increasing the percentage of Americans with health insurance coverage. Even within this year's first quarter, the uninsured rate fell consistently, from 16.2% in January to 15.6% in February to 15.0% in March. And within March, the rate dropped more than a point, from 15.8% in the first half of the month to 14.7% in the second half -- indicating that enrollment through the healthcare exchanges increased as the March 31 deadline approached."
