REVISION OF INDUSTRIAL PRODUCTION AND CAPACITY UTILIZATION
In fall 2004, the Federal Reserve Board plans to issue an 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; the date of the revision is subject to the availability of the
comprehensive source data from the Census Bureau's 2002 Economic Census. In addition to the
inclusion of these data, the revised IP indexes will incorporate 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
will also be introduced. The updating will include 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 will be 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 Department of Energy, and other
organizations. The statistics on the industrial use of electric power will incorporate additional
information received from utilities for the past few years and will include available data from the
2002 Economic Census.
Once the revision is published, it will be made available on the Board's web site at
www.federalreserve.gov/releases/G17. The revised data will also be available through the web
site of the Department of Commerce. Further information on these revisions is available from
the Board's Industrial Output Section (telephone 202-452-3197).
