And, according to Enroll America/Civis Analytics’ uninsured model, uninsured rates for non-elderly adults have declined by nearly 50 percent as well, dropping from 16.4 percent in 2013 to 8.3 percent in 2016.

The Enroll America/Civis Analytics uninsured model provides our best estimate of uninsured rates by geography and demographic group. For smaller geographies — such as ZIP codes and counties — and demographic groups that contain fewer people, Enroll America’s estimates may show increased variation from the actual uninsured rate in these areas.
