Wyoming
According to EIA, Wyoming has led the U.S. in coal production since 1986. Using historical coal production data from EIA and the U.S. Mine Safety and Health Administration, it is evident that Wyoming coal production peaked in 2008 with over 467 million short ton. In 2019, about 277 million short ton were produced in the state, a 40.7 percent decrease from the 2008 production level. In addition, it is clear that Wyoming employment followed the production trend observed. Employment in coal mines peaked in 2009 with 7,054 employees. In 2019, 5,399 employees worked in coal mines in the state, a 23.5 percent decrease from the 2009 employment level.
County Level
The majority of coal produced originates from Campbell, Converse, Sweetwater, and Lincoln counties. Consequently, the majority of Wyoming employment in coal mines is concentrated in the same counties.
