G17: G.17 Annual Revision Planned to be Released on November 24, 2026

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 November 24, 2026. The base year for the revised indexes will be 2022. New annual benchmark data for manufacturing from the U.S. Census Bureau for 2023 and 2024 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 2025 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.
