The Federal Reserve Board plans to issue its annual revision to the index of industrial production (IP) and the related measures of capacity utilization around the end of the first quarter of 2018. New annual benchmark data for 2016 will be incorporated for manufacturing, as will other annual data, including information on the mining of metallic and nonmetallic minerals (except fuels). The updated IP indexes will include revisions to the monthly indicator (either product data or input data) and to seasonal factors for each industry. In addition, the estimation methods for some series may be changed. Any modifications to the methods for estimating the output of an industry will affect the index from 1972 to the present.Capacity and capacity utilization will be revised to incorporate data through the fourth quarter of 2017 from the U.S. Census Bureau's Quarterly Survey of Plant Capacity Utilization along with new data on capacity from the U.S. Geological Survey, the U.S. Department of Energy, and other organizations.
