Industrial Production and Capacity Utilization

ANNUAL REVISION OF INDUSTRIAL PRODUCTION AND CAPACITY UTILIZATION

The Federal Reserve Board plans to issue an annual revision to the index of industrial production (IP) and the related measures of capacity and capacity utilization late this year; the publication date is tentatively December 11 but is conditional on the date of issuance of the 2005 Annual Survey of Manufactures. An announcement will be posted on the Board's website at www.federalreserve.gov/releases/G17 when the final date for the G.17 revision is determined.

The revised IP indexes will incorporate data from the 2004 and 2005 Annual Surveys of Manufactures and from selected editions of the 2004 and 2005 Current Industrial Reports, all from the U.S. Census Bureau. Annual data from the U.S. Geological Survey regarding metallic and nonmetallic minerals (except fuels) for 2004 and 2005 will also be incorporated. The updating will include revisions to the monthly indicator for each industry (either product data or input data) and to seasonal factors.

Capacity and capacity utilization will be revised to incorporate preliminary data from the Census Bureau's 2005 Survey of Plant Capacity, which covers manufacturing, along with new data on capacity from the U.S. Geological Survey, the Department of Energy, and other organizations.

Once the revision is published, it will be available on the Board's website at www.federalreserve.gov/releases/G17. The revised data will also be available through the website of the Department of Commerce. Further information on these revisions can be obtained from the Board's Industrial Output Section (telephone number 202-452-3197).
