States with the highest, lowest uninsured rates post-Obamacare

The national health uninsured rate decreased more than 3.5 percentage points to 14.22% following the Jan. 1 implementation of the Affordable Care Act (ACA), according to WalletHub, a financial social network, in its 2014 Health Insurance Coverage Report. Using data from the Kaiser Family Foundation, which details the number of private health plan enrollees under ACA who previously lacked health insurance–and therefore gained coverage–WalletHub compared state insurance rates pre- and post-ACA.

WalletHub combines this data with the number of new Medicaid recipients and private plan enrolless under ACA to offer an initial project of uninsured rates for 43 states and the District of Columbia. Data is not available for Connecticut, Delaware, Maine, Michigan, New Hampshire, North Dakota and Vermont.
