People employed in farming, fishing, and forestry and construction and extraction – among the most hazardous occupations in the U.S. - have the highest prevalences of not having health insurance.

That’s according to a new report from the CDC that sheds light on the number of employed people in the U.S. who lack health insurance – and on which types of workers are most affected. According to the report, during 2014, 12.7% of workers aged 18–64 years were uninsured (a 21% decline from 2013). Declines occurred in all demographic groups.
