An estimated 9.4 percent of U.S. residents, or 30.4 million people, lacked health insurance when surveyed in 2018, according to a report released today by the Centers for Disease Control and Prevention. That’s not significantly different from the survey’s uninsured rate in 2017, but 18.2 million fewer people than in 2010, the authors said. The uninsured rate for adults under age 65 was 9.9 percent in Medicaid expansion states, compared with 18.7 percent in non-expansion states. The report also includes estimates for various demographic groups and by health insurance marketplace type. Adults under age 65 were more likely to be uninsured in states with a federally-facilitated marketplace (16.4 percent) than in states with a state-based or partnership marketplace (9.5 percent). Nearly half of adults (46 percent) were enrolled in a high-deductible health plan in 2018, up from 25 percent in 2010.
