On Tuesday, Gallup released its quarterly data on the number of Americans without health insurance. It found that, in the fourth quarter of 2017, an estimated 12.2 percent of American adults didn't have health insurance coverage. That figure is up from about 10.9 percent in the fourth quarter of 2016, which marked the lowest percentage of uninsured Americans ever recorded by Gallup.
The chart below, from Gallup, illustrates how health insurance coverage rose during the Obama administration, and then dropped during the first year of the Trump administration:
The uninsured rate increased the most among people aged 18 to 25 (up by 2 percent), African Americans (up by 2.3 percent), Hispanics (up by 2.2 percent), and Americans earning less than $36,000 (up by 2 percent).
