Industrial Production and Capacity Utilization

ANNUAL REVISION OF INDUSTRIAL PRODUCTION AND CAPACITY UTILIZATION

On December 11, 2006, the Federal Reserve Board issued its annual revision to the index of industrial production (IP) and the related measures of capacity and capacity utilization. The revised IP indexes incorporated 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 were also incorporated. The updating included revisions to the monthly indicator for each industry (either product data or input data) and to seasonal factors.

Capacity and capacity utilization were 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.

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