U.S. Census Bureau: Income, Poverty and Health Insurance Coverage in the United States: 2014

In its annual report on poverty and the uninsured, the U.S. Census Bureau reports that: “The percentage of people without health insurance coverage for the entire 2014 calendar year was 10.4 percent, down from 13.3 percent in 2013. The number of people without health insurance declined to 33.0 million from 41.8 million over the period.” (Our analysis shows that virtually all of the increase in the number of people with health insurance has come from Medicaid expansion.)
