An estimated 27.3 million U.S. residents lacked health insurance when surveyed in the first three months of 2016, 1.3 million fewer than in 2015, according to a report released today by the Centers for Disease Control and Prevention. The proportion of residents who were uninsured when interviewed for the National Health Interview Survey fell 0.5 percentage point, to 8.6% from 9.1% in 2015. The uninsured rate for adults under age 65 was 9.2% in Medicaid expansion states, compared with 16.7% in non-expansion states. The report also includes estimates by Health Insurance Marketplace type and for various demographic groups.
