The number of people without health insurance rose by 1.9 million people from 2017 to 2018 despite strong economic performance, according to a report released Tuesday by the U.S. Census Bureau.

The total number of uninsured was 27.5 million, or 8.5% of the population, a 0.5 percentage point increase from 2017. The change was driven by a decline in government coverage of 0.4 percentage points and by a decline in insurance coverage among Hispanics.
