A New Gallup poll released this week found that 12.2% of all Americans age 18 and older did not have health insurance coverage, an increase of 1.3% over 2016. These findings are based on a nationwide survey of over 25,000 people living in all 50 states and D.C. with margin of error of +/- 0.4%. Gallup did not release state-specific data.

The annual increase in the uninsured rate is the largest reported since 2008 and means approximately 3.2 million more Americans were without health insurance in 2017 than 2016. Notably, the largest decline in coverage was among those indicating they purchased coverage on the individual market, down 1% from 2016.
