U.S. union membership rate in the mining, quarrying, and gas industry 2000-2023
While union membership has been on the decline nationwide since 2000, the mining, quarrying, and oil and natural gas industry has seen a recent increase. The industry had relatively high rates of union membership compared with averages across all industries at the start of the century. In 2000, around nine percent of workers were members of unions compared to 11.3 percent of industry workers. The rate spiked in 2022 after union membership in oil and gas reached an all time low in 2019. However, membership once again fell to 4.3 percent in 2023.
