This comprehensive resource is published on an annual basis, and is considered the earliest Government publication to furnish estimates covering nonfuel mineral industry data for the United States and worldwide. Each chapter of this 2015 edition includes information on events, trends, and issues for each mineral commodity as well as discussions and tabular presentations, including data sheets on domestic industry structure, Government programs, tariffs, 5-year salient statistics, and world production and resources for more than 90 minerals and materials. The Mineral Commodity Summaries (MCS) is the earliest comprehensive source of 2014 mineral production data for the world. More than 90 individual minerals and materials are covered by two-page synopses. For mineral commodities for which there is a Government stockpile, detailed information concerning the stockpile status is also included in the two-page synopsis.
