Sept. 18, 2017 – U.S. mine and plant production data for 14 selected mineral commodities are provided monthly (or quarterly) by the U.S. Geological Survey to the Board of Governors, Federal Reserve System (FRS), for use in preparing its index of industrial production and the related capacity indexes and capacity-utilization rates. These measures cover manufacturing, mining, and electric and gas utilities, and they are among the key economic indicators monitored by the FRS for guidance in determining national monetary policy. The combined production of construction materials (cement, construction sand and gravel, crushed stone, and gypsum) in the second quarter of 2017 was 46 percent higher compared with that in the first quarter of 2017 due to cyclical seasonal fluctuations but was slightly lower than that in the second quarter of 2016.
