1Includes data from the commodity chapters published in the Minerals Yearbook as they were completed and released through December 2020.

2Production as measured by mine shipments, sales, or marketable production (including consumption by producers). Mine output measured as sold or used by producers is primarily shown in the tables, because values can be assigned. Where sold or used data are not available, actual mine output is used as the production measurement and value is estimated average price of the mineral commodity for that year. Data are reported in gross weight unless otherwise specified.

3Data are rounded to no more than three significant digits; may not add to totals shown.

7Withheld to avoid disclosing company proprietary data; value included in "Undistributed" in the U.S. total value.
