r Revised. p Preliminary.
Note. The statistics in this release cover output, capacity, and capacity utilization in the U.S. industrial sector, which is defined by the Federal Reserve to comprise
manufacturing, mining, and electric and gas utilities. Mining is defined as all industries in sector 21 of the North American Industry Classification System (NAICS);
electric and gas utilities are those in NAICS sectors 2211 and 2212. Manufacturing comprises NAICS manufacturing industries (sector 31-33) plus the logging industry
and the newspaper, periodical, book, and directory publishing industries. Logging and publishing are classified elsewhere in NAICS (under agriculture and information
respectively), but historically they were considered to be manufacturing and were included in the industrial sector under the Standard Industrial Classification (SIC)
system. In December 2002 the Federal Reserve reclassified all its industrial output data from the SIC system to NAICS.

increased 0.6 percent, and the index for utilities bounced up 4.1 percent after having fallen 4.6 percent in
September. The rate of capacity utilization for total industry rose 0.1 percentage point, to 82.2 percent, a level
1.2 percentage points above its 1972–2005 average.
Market Groups
The output of consumer goods declined 0.5 percent in October. The index for durable consumer goods
fell 2.6 percent; a drop of 4.6 percent in the production of automotive products accounted for most of the
decrease. The index for automotive products stood 11.5 percent below its year-earlier level. The decrease in
automotive products in October resulted from another decrease in light truck assemblies and a strike at a major
producer of tires. Light truck assemblies stood at an annual rate of 5.6 million units in October, compared with a
rate of 7.0 million units in the fourth quarter of 2005. The output of home electronics increased 1.0 percent in
October, while the production indexes for miscellaneous goods and for appliances, furniture, and carpeting
declined modestly. The output of consumer non-energy nondurables edged up, as increases in the indexes for
clothing and for paper products slightly more than offset a small decline in the index for foods and tobacco; the
output of chemical products was unchanged. The index for consumer energy products rose 0.8 percent after
having fallen sharply in September.
The output of business equipment increased 0.7 percent in October; all major categories registered gains
and remained well above their year-earlier levels. The production of defense and space equipment moved up
0.4 percent to a level 5-1/4 percent higher than its level of a year earlier. The index for construction supplies
increased 0.2 percent and was only slightly above its year-earlier level; the index for business supplies posted a
gain of 1.1 percent. Materials output increased 0.4 percent in October; the output of non-energy materials was
unchanged, but the production of energy materials rose 1.3 percent.
Industry Groups
Manufacturing output decreased 0.2 percent in October. The production of both durable and nondurable
goods decreased, but the output of non-NAICS manufacturing (logging and publishing) rose. Capacity utilization
in manufacturing declined 0.3 percentage point, to 80.7 percent, a level that was 0.9 percentage point above its
1972–2005 average. Among durable goods categories, the changes in output were mixed. The production of
motor vehicles and parts, primary metals, and wood products recorded large drops, while substantial gains were
reported in the output of computer and electronic products and of aerospace and miscellaneous transportation
equipment. Among nondurables, which declined 0.4 percent in October, the largest drops were in the indexes for
petroleum and coal products, plastics and rubber products, and textile and product mills. Elsewhere in
nondurables, the indexes for apparel and leather and for printing and support registered substantial output gains.
The increase of 4.1 percent in output at utilities in October largely reflected colder-than-normal
conditions following mild temperatures in September. The output at mines moved up 0.6 percent in October and
was 13.8 percent above its hurricane-related trough in October 2005.
Capacity utilization for industries at the crude stage of processing increased 0.3 percentage point, to
89.6 percent. The utilization rate for industries at the primary and semifinished stages increased 0.3 percentage
point, to 83.2 percent, and the utilization rate for finished goods producers declined 0.4 percentage point, to
79.3 percent.

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).

Aggregation Methodology and Weights. The aggregation method
for the IP index is a version of the Fisher-ideal index formula. (For a
detailed discussion of the aggregation method, see Federal Reserve
Bulletin February 1997 and March 2001.) In the IP index, series that
measure the output of an individual industry are combined using
weights derived from their proportion in the total value-added output
of all industries. The IP index, which extends back to 1919, is built as
a chain-type index since 1972. The current formula for the growth in
monthly IP (or any of the sub-aggregates) since 1972 is the geometric
mean of the change in output (I), and, as can be seen below, is
computed using the unit value added estimate for the current month
(pm ) and the estimate for previous month:

E XPLANATORY N OTE
The Industrial Production and Capacity Utilization statistical
release, which is published around the middle of the month, reports
measures of output, capacity, and capacity utilization in
manufacturing, mining, and the electric and gas utilities industries.
More detailed descriptions of industrial production and capacity
utilization are available at www.federalreserve.gov/releases/G17 at
the Board’s World Wide Web site. In addition, files containing data
shown in the release, more detailed series that were published in the
G.17 prior to December 2000, and historical data are available at the
Board’s Web site. Instructions for searching for and downloading
specific series are provided as well. For paid access to the data files
through the Department of Commerce’s Economic Bulletin Board or

The IP proportions (typically shown in the first column of the relevant
tables in the G.17 release) are estimates of the industries’ relative
contributions to overall growth in the following year. For example, the
relative importance weight of the motor vehicles and parts industry is
about 8 percent. If output in this industry increased 10 percent in a
month, then this gain would boost growth in total IP by 8/10
percentage point (0.08 x 10% = 0.8%). To assist users with
calculations, the Federal Reserve’s web site provides supplemental
monthly statistics that represent the exact proportionate contribution
of a monthly change in a component index to the monthly change in
the total index (www.federalreserve.gov/
releases/G17/ipdisk/ipweights.sa).

I NDUSTRIAL P RODUCTION
Coverage. The industrial production (IP) index measures the real
output of the manufacturing, mining, and electric and gas utilities
industries; the reference period for the index is 2002. Manufacturing
consists of those industries included in the North American Industry
Classification System, or NAICS, definition of manufacturing plus
those industries-logging and newspaper, periodical, book and
directory publishing-that have traditionally been considered to be
manufacturing and included in the industrial sector. For the period
since 1997, the total IP index has been constructed from 300
individual series based on the 2002 North American Industrial
Classification System (NAICS) codes. These individual series are
classified in two ways: (1) market groups, and (2) industry groups.
Market groups consist of products and materials. Total products are
the aggregate of final products, such as consumer goods and
equipment, and nonindustrial supplies (which are inputs to
nonindustrial sectors). Materials are inputs in the manufacture of
products. Major industry groups include three-digit NAICS industries
and aggregates of these industries—for example, durable and
nondurable manufacturing, mining, and utilities. A complete
description of the market and industry structures, including details
regarding series classification, relative importance weights, and data
sources, is available on the Board’s web site
(www.federalreserve.gov/releases/G17/About.html). Changes in
output for the market and industry groups are summarized in table 1
and the levels of output (in index form) are shown in table 4. Special
aggregates, that highlight the relative importance and contributions of
several key industries, such as high-technology and motor vehicles,
are summarized in tables 2 and 5. For a detailed description of the
contents of the statistical tables, see below.

Timing. The first estimate of output for a month is published around
the 15th of the following month. The estimate is preliminary (denoted
by the superscript “p” in tables) and subject to revision in each of the
subsequent three months as new source data become available.
(Revised estimates are denoted by the superscript “r” in tables.) For
the first estimate of output for a given month, about 70 percent of the
source data (in value-added terms) are available; the fraction of
available source data increases to about 85 percent for estimates in the
second month that the estimate is published, 96 percent in the third
month, and 97 percent in the fourth month. Data availability by data
type is summarized in the table below:
Availability of Monthly IP Data in Publication Window
(Percent of value added in 2004)
Month of estimate

Source data. On a monthly basis, the individual indexes of industrial
production are constructed from two main types of source data: (1)
output measured in physical units and (2) data on inputs to the
production process, from which output is inferred. Data on physical
products, such as tons of steel or barrels of oil, are obtained from
private trade associations and from government agencies; data of this
type are used to estimate monthly IP wherever possible and
appropriate. Production indexes for a few industries are derived by
dividing estimated nominal output (calculated using unit production
or sales and unit values) by a corresponding Fisher price index; the
most notable of these fall within the high-technology grouping and
include computers, communications equipment, and semiconductors.
When suitable data on physical product are not available, estimates of
output are based on production-worker hours by industry. Data on
hours worked by production workers are collected in the monthly
establishment survey conducted by the Bureau of Labor Statistics.
The factors used to convert inputs into estimates of production are
based on historical relationships between the inputs and the
comprehensive annual data used to benchmark the IP indexes; these
factors also may be influenced by technological or cyclical
developments. The annual data used in benchmarking the individual
IP indexes are constructed from a variety of source data, such as the
quinquennial Censuses of Manufactures and Mineral Industries and
the Annual Survey of Manufactures, prepared by the Bureau of the
Census; the Minerals Yearbook, prepared by the United States
Geological Survey of the Department of the Interior; and publications
of the Department of Energy.

The physical product group includes series based on either monthly or
quarterly data. As can be seen in the first line of the table, in the first
month, a physical product indicator is available for about half of the
series (in terms of value added) that ultimately are based on physical
product data (25 percent out of total of 52 percent). Of the 25 percent,
about two-thirds (17 percent of total IP) include series that are derived
from weekly physical product data and for which actual monthly data
may lag up to several months. On average, quarterly product data are
received for the third estimate of industrial production. Specifically,
quarterly data are available for the second estimate of the last month
of a quarter, the third estimate of the second month of a quarter, and
the fourth estimate of the first month of a quarter. About 3 percent of
the source data for monthly IP—all physical product measures—are
available too late for direct inclusion in the current index and are
incorporated at the time of an annual historical revision.
Seasonal adjustment. Individual series are seasonally adjusted using
Census X-12 ARIMA. For series based on production-worker hours,
the current seasonal factors were estimated with data through April

17

2006; for other series, the factors were estimated with data through at
least June 2005. Series are pre-adjusted for the effects of holidays or
the business cycle when appropriate. For the data since 1972, all
seasonally adjusted aggregate indexes are calculated by aggregating
the seasonally adjusted indexes of the individual series.

related capacity index.
Consistency. A major aim is that the Federal Reserve utilization rates
be consistent over time so that, for example, a rate of 85 percent
means about the same degree of tightness that it meant in the past. A
major task for the Federal Reserve in developing reasonable and
consistent time series of capacity and utilization is dealing with
inconsistencies between the movements of the industrial production
index and the survey-based utilization rates. The McGraw-Hill/DRI
Survey, now discontinued, was the primary source of manufacturing
utilization rates for many years. This was a survey of large companies
that reported, on average, higher utilization rates than those reported
by establishments covered by the SPC (currently the primary source
of factory operating rates) for the fourteen years they overlapped.
Adjustments have been made to keep the industry utilization rates
currently reported by the Federal Reserve roughly in line with rates
formerly reported by McGraw-Hill. As a consequence, the rates
reported by the Federal Reserve tend to be higher than the rates
reported in the SPC.

Reliability. The average revision to the level of the total IP index,
without regard to sign, between the first and the fourth estimates was
0.27 percent during the 1987–2004 period. The average revision to
the percent change in total IP, without regard to sign, from the first to
the fourth estimates was 0.21 percentage point during the 1987–2004
period. In most cases (about 86 percent), the direction of change in
output indicated by the first estimate for a given month is the same as
that shown by the fourth estimate.
Rounding. The published percent changes are calculated from
unrounded indexes, and may not be the same as percent changes
calculated from the rounded indexes shown in the release.
C APACITY U TILIZATION

Perspective. Over the 1972–2005 period, the average total industry
utilization rate is 81.0 percent; for manufacturing, the average factory
operating rate has been 79.8 percent. Industrial plants usually operate
at capacity utilization rates that are well below 100 percent: none of
the broad aggregates has ever reached 100 percent. For total industry
and total manufacturing, utilization rates have exceeded 90 percent
only in wartime. The highs and lows in capacity utilization shown in
table 7 are specific to each series and do not all occur in the same
month.

Overview. The Federal Reserve Board constructs estimates of
capacity and capacity utilization for industries in manufacturing,
mining, and electric and gas utilities. For a given industry, the
capacity utilization rate is equal to an output index (seasonally
adjusted) divided by a capacity index. The Federal Reserve Board’s
capacity indexes attempt to capture the concept of sustainable
maximum output—the greatest level of output a plant can maintain
within the framework of a realistic work schedule, after factoring in
normal downtime and assuming sufficient availability of inputs to
operate the capital in place.

Coverage. Capacity indexes are constructed for 85 detailed industries
(67 in manufacturing, 16 in mining, and 2 in utilities), which mostly
correspond to industries at the three- and four-digit NAICS level.
Estimates of capacity and utilization are available for a variety of
groups, including durable and nondurable manufacturing, total
manufacturing, mining, utilities, and total industry. Manufacturing
consists of those industries included in the North American Industry
Classification System, or NAICS, definition of manufacturing plus
those industries—logging and newspaper, periodical, book and
directory publishing—that have traditionally been considered to be
manufacturing and included in the industrial sector. Also, special
aggregates are available, such as high-tech industries and
manufacturing excluding high-tech industries.

Industrial Production—1986 Edition contains a more detailed
description of the other methods used to compile the industrial
production index, plus a history of its development, a glossary of
terms, and a bibliography. The major revisions to the IP indexes and
capacity utilization since 1990 have been described in the Federal
Reserve Bulletin (April 1990, June 1990, June 1993, March 1994,
January 1995, January 1996, February 1997, February 1998, January
1999, March 2000, March 2001, March 2002, April 2003, Winter
2004, Winter 2005).

Source Data. The monthly rates of capacity utilization are designed
to be consistent with both the monthly data on production and the
periodically available data on capacity and utilization. Because there
is no direct monthly information on overall industrial capacity or
utilization rates, the Federal Reserve first estimates annual capacity
indexes from the source data. Capacity data reported in physical units
from government sources (primarily from the U.S. Geological Survey
and the Department of Energy’s Energy Information Administration)
and trade sources are available for portions of several industries in
manufacturing (e.g., paper, industrial chemicals, petroleum refining,
motor vehicles), as well as for electric utilities and mining; these
industries represent about 21 percent of total industrial capacity.
When physical product data are unavailable for manufacturing
industries, capacity indexes are based on responses to the Bureau of
the Census’s Survey of Plant Capacity (SPC); these industries account
for a bit less than 75 percent of total industry capacity. In the absence
of utilization data for a few mining and petroleum series, capacity is
based on trends through peaks in production (roughly 4 percent of
total industry capacity). A detailed description of the methodology
used to construct the capacity indexes is available on the Board’s web
site (www.federalreserve.gov/releases/G17/cap notes.html).

Aggregation Methodology. Monthly capacity aggregates are
calculated in three steps: (1) utilization aggregates are calculated on
an annual basis through the most recent full year as capacity-weighted
aggregates of individual utilization rates; (2) the annual aggregate
capacity is derived from the corresponding production and utilization
aggregates; (3) the monthly capacity aggregate is obtained by
interpolating with a Fisher index of its constituent monthly capacity
series. Utilization rates for the individual series and aggregates are
calculated by dividing the pertinent monthly production index by the
