REVISION OF INDUSTRIAL PRODUCTION AND CAPACITY UTILIZATION
On December 22, 2004, the Federal Reserve Board issued its annual revision to the index
of industrial production (IP), the related measures of capacity and capacity utilization, and the
data on industrial use of electric power. Comprehensive source data from the Census Bureau's
2002 Economic Census were incorporated into the production database. In addition to these
data, the revised IP indexes reflect data from selected editions of the Census Bureau's 2002 and
2003 Current Industrial Reports. Annual data from the U.S. Geological Survey regarding
metallic and nonmetallic minerals (except fuels) for 2002 and 2003 were also introduced. The
updating also included revisions to the monthly indicator for each industry (either physical
product data, production-worker hours, or electric power usage) and revisions to seasonal
factors.
Capacity and capacity utilization were revised to incorporate preliminary data from the
Census Bureau's 2003 Survey of Plant Capacity, which covers manufacturing, along with new
data on capacity from the U.S. Geological Survey, the U.S. Department of Energy, and other
organizations. The statistics on the industrial use of electric power incorporated additional
information received from utilities for the past few years and included available data from the
2002 Economic Census.
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 202-452-3197).
