The Federal Reserve Board plans to issue its annual revision to the indexes of industrial
production (IP) and the related measures of capacity utilization on March 28, 2023. New annual
benchmark data for manufacturing for 2021 will be incorporated, as well as 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 for manufacturing
through the fourth quarter of 2022 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.
