IE Questions: In Wyoming, How Much Coal Does A Miner Mine?

Even though Wyoming has been the top coal-producing state since 1988 and its coal culture runs deep, the image of the Appalachian coal miner persists in American popular culture. Why? Perhaps because most coal miners still work in Appalachia, even though most coal comes from Wyoming. In 2012, for example, Wyoming produced about 40% of U.S. coal but employed only 8% of coal miners.
