The portion of people in the United States with health insurance rose slightly in 2016, according to a census report released Tuesday, though analysts said they were unable to determine how much of that increase was attributable to Obamacare, and how much was due to an improved economy.

According to the census data, 91.2 percent of people had health insurance in the U.S. in 2016, up 0.3 percentage points from 2015.
