October 14, 2005

INDUSTRIAL PRODUCTION AND CAPACITY UTILIZATION
Industrial production dropped 1.3 percent in September, as Hurricanes Katrina and Rita and a strike at a
major aircraft producer significantly reduced output. At 118.0 percent of its 1997 average, output in September was
2.0 percent above its year-earlier level; for the third quarter as a whole, production rose 1.3 percent at an annual rate. For
September, manufacturing output decreased 0.5 percent; for the quarter, it increased 2.3 percent at an annual rate. The
output of mining, which includes many industries that were hit hard by storms, declined 9.1 percent in September and fell
16.5 percent at an annual rate for the third quarter. Production at utilities declined 0.9 percent in September, but output

r Revised. p Preliminary.
NOTE-- The statistics in this release cover output, capacity, and capacity utilization in the industrial sector, which the Federal Reserve defines as manufacturing,
mining, and electric and gas utilities. Manufacturing comprises those industries included in the North American Industry Classification System, or NAICS,
definition of manufacturing plus the logging and newspaper, periodical, book and directory publishing industries that have traditionally been considered
manufacturing and included in the industrial sector.

for the third quarter rose at an annual rate of 10.7 percent. Capacity utilization for total industry dropped 1.2 percentage
points, to 78.6 percent, a rate that is 0.6 percentage point above its year-earlier level but 2.4 percentage points below its
1972--2004 average.
In September, storm-related production declines are estimated to have held down the change in total
industrial production about 1.7 percentage points; in August, storm-related losses reduced the change in total industrial
production nearly 0.4 percentage point. Oil and gas extraction and petroleum refining suffered because of the storms,
which contributed importantly to a decrease of 5 percent in production by the energy sector in September. The largest
effect of the storms outside the energy sector was in the manufacture of industrial chemicals. The strike in the aircraft
industry reduced the change in total industrial output almost 0.5 percentage point.
Market Groups
The output of consumer goods rose 0.2 percent in September; for the third quarter this index advanced at an
annual rate of 3.4 percent. The production of durable goods increased 1.8 percent in September, and all major categories
posted gains. The output of automotive products rose 2.4 percent, and for the third quarter, it increased at an annual rate
of 18.6 percent. The indexes for home electronics; appliances, furniture, and carpeting; and miscellaneous goods also
rose in September. The output of consumer nondurable goods decreased 0.4 percent, for its third consecutive monthly
decline; however, this index increased at an annual rate of 0.6 percent in the third quarter. The production of non-energy
nondurable consumer goods was unchanged in September. The output of foods and tobacco rose 0.1 percent, and the
production of consumer chemical products increased 0.3 percent. However, the index for paper products declined for a
fourth consecutive month. Hurricane-related shutdowns contributed to a drop of 2.2 percent in the output of consumer
energy products in September.
The index for business equipment declined 3.7 percent in September; the aircraft manufacturing strike was
largely responsible for a drop of 24.3 percent in the production of transit equipment. The output of information
processing equipment advanced 2.2 percent; for the third quarter, this index moved up at an annual rate of 23.4 percent.
The production of industrial and other equipment rose 0.4 percent for the month and at an annual rate of 7.2 percent for
the quarter. The production of defense and space equipment fell 3.4 percent in September, mainly as a result of
storm-related effects on shipbuilding. The index for construction supplies increased 0.2 percent, but the output of
business supplies declined 0.5 percent.
The output of materials fell 2.1 percent in September; the output of non-energy materials slipped 0.2 percent,
and the production of energy materials dropped 6.8 percent. Among non-energy materials, output rose for all major
categories of durable goods materials, and output fell for all major categories of nondurable materials. Storm-related
disruptions contributed to the decreases in the output of energy materials and the output of chemical materials (a major
category within nondurable materials).
Industry Groups
Manufacturing output fell 0.5 percent in September. The production of durables edged down 0.1 percent but
increased at an annual rate of 7.6 percent in the third quarter. Gains in durables were widespread in September, with the
only notable exception being the strike-affected aerospace and miscellaneous transportation equipment category. The
output of primary metals advanced 1.7 percent and increased at an annual rate of 3.6 percent in the third quarter after two
quarters of decline. The production of computer and electronic products accelerated in the third quarter and was led by
gains in the communications equipment industry. The production of motor vehicles and parts advanced 2.2 percent in
September and rose at an annual rate of 12.5 percent in the third quarter after having declined in the second quarter.
Fabricated metal products; machinery; electrical equipment, appliances, and components; furniture and related products;
and miscellaneous manufacturing also posted solid gains in output for the quarter. The production of nondurables
decreased 1.2 percent in September. Hurricane-related shutdowns in the Gulf Coast region contributed to a drop of
3.3 percent in the production of chemicals and a decrease of 6.4 percent in the output of petroleum and coal products.
Most other major nondurable goods industries posted small gains; however, the output of plastics and rubber products
climbed 1.8 percent, and the production of paper declined for a third consecutive month. The output of non-NAICS
2

manufacturing industries (publishing and logging) together declined 0.5 percent. Capacity utilization in manufacturing
fell to 77.9 percent, a level 1.1 percentage points above that of September 2004.
The output at mines dropped 9.1 percent in September, a decrease driven by curtailments in the extraction of
oil and gas in the Gulf of Mexico. Capacity utilization in mining fell to 79.1 percent. The output at utilities declined
0.9 percent, and the industry operating rate declined to 86.3 percent.
For industries by stage of process, capacity utilization at the crude stage sank 7.6 percentage points, to
77.6 percent; at the primary and semifinished stages, it declined 0.2 percentage point, to 80.2 percent; and at the finished
stage, it fell 0.6 percentage point, to 77.6 percent.
Calculation of Hurricane Effects
Government and industry sources were used to measure the impact of Hurricanes Katrina and Rita on
industrial production. Losses in the extraction of oil and gas are based on shut-in resources in the Gulf of Mexico
reported by the Mineral Management Survey of the U.S. Department of the Interior. Information from the U.S.
Department of Energy on production curtailments was used to estimate the impact of the storms on petroleum refining.
Effects in the chemicals industry are based on detailed product data from an industry source. Outside of these industries,
lost output is assumed to be proportional to U.S. Census Bureau measures of industry employment counts for counties
declared eligible for disaster assistance by the Federal Emergency Management Agency.

Revision of Industrial Production and Capacity Utilization
The Federal Reserve Board plans to issue its annual revision to the index of industrial
production (IP) and the related measures of capacity and capacity utilization on November 7, 2005. The
production indexes will be revised throughout to reflect a new comparison base year of 2002. The revised
IP indexes will incorporate data from the 2003 Annual Survey of Manufactures and from selected editions of
the 2003 and 2004 Current Industrial Reports, all from the Census Bureau. Annual data from the Geological
Survey regarding metallic and nonmetallic minerals (except fuels) for 2003 and 2004 will also be
introduced. The updating will include revisions to the monthly indicator for each industry (either product
data or input data) and revisions to seasonal factors.
Capacity and capacity utilization will be revised to incorporate preliminary data from the
Census Bureau’s 2004 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 published, the revision will be available on the Board’s website at
www.federalreserve.gov/releases/G17. The revised data will also be available on the website of the U.S.
Department of Commerce. Further information on these revisions is available from the Board’s Industrial
Output Section (telephone 202-452-3197).

EXPLANATORY NOTE
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. The release also includes monthly
indexes on the use of electric power in manufacturing and mining. More
detailed descriptions of industrial production, capacity utilization, and
electric power 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 World Wide Web site, please
call STAT-USA at 1-800-STAT-USA or 202-452-1986. Diskettes
containing historical data and the data published in this release also are
available from the Board of Governors of the Federal Reserve System,
Publications Services, 202-452-3245.
INDUSTRIAL PRODUCTION
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 1997. 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.
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 either
production-worker hours or electric power use by industry. Data on hours
worked by production workers are collected in the monthly establishment
survey conducted by the Bureau of Labor Statistics. The data on electric
power use are described below. 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

18

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.
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:
IA
m
=
IA
m–1



Imp m–1

Im–1p m–1

×

 Imp m
 Im–1p m

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 5 percent. If output in this industry increased 10 percent in a month,
then this gain would boost growth in total IP by ½ percentage point (0.05
x 10% = 0.5%). 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).
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 59 percent of the source data (in value-added
terms) are available; the fraction of available source data increases to about
86 percent for estimates in the second month that the estimate is published,
96 percent in the third month, and 96 percent in the fourth month. Data
availability by data type is summarized in the table below:

NOTE—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 (24 percent out of total of 59 percent). Of the 24 percent,
about five-- sixths (20 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 4 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 September
2004; for other series, the factors were estimated with data through at least
June 2004. 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.
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
85 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.
CAPACITY UTILIZATION
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.
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 20 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 5 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

19

individual series and aggregates are calculated by dividing the pertinent
monthly production index by the 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.
Perspective. Over the 1972--2004 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.
ELECTRIC POWER
Coverage. Electric power data for sales by utilities to industry users and
for electric power produced by cogenerators (manufacturing and mining
firms that produce electricity for their own use or to sell to a utility) are
generally collected at the 4-digit NAICS and 3-digit SIC level for mining
and manufacturing. Aggregates for 3-digit industries, as well as for total
mining, durable, nondurable, total manufacturing and total industrial
electric power use, are computed. 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. An aggregate showing total industry excluding nuclear
nondefense is shown separately because the value-added proportion for
the nondefense nuclear material series (part of NAICS 3251) in total IP is
considerably less than its share of total electric power use. In addition,
aggregates for utility sales to industrial users and industry generation are
computed. While only the major aggregates are shown in the release, data
for the 3- and 4-digit industries are available on the Board’s web site
(www.federalreserve.gov/releases/G17).
Source Data. Electric power data are collected from a sample of utilities
and cogenerators covering all twelve Federal Reserve Districts. The
primary criterion for inclusion of a utility in the panel is whether the utility
provides electric power to industrial customers. A comparison of Federal
Reserve kilowatt-hour aggregates to estimates from the 1997 Census of
Manufactures (the most recent available) and recent reporting panel
statistics suggests the Federal Reserve data cover about 50 percent of the
overall sales to manufacturing in that year. The cogeneration panel covers
about 50 percent of cogeneration used directly by manufacturers. In order
to provide more complete coverage and correct for any shortcomings of
the survey, the series are benchmarked at the 4-digit industry level to the
latest available data from the Annual Survey of Manufactures and the
Census of Manufactures.
Methodology. The data we receive from utilities and cogenerators are
edited for anomalies and aggregated, using self weights, to the 4-digit
NAICS industry levels and above. Where reports are late or unavailable
for some reason, responses are estimated.
Seasonal Adjustment. Series are seasonally adjusted at the 4-digit
NAICS level, with seasonally-adjusted aggregates typically computed as
sums of seasonally adjusted components. The seasonal adjustment
procedure (Census X-12 program) is used without trading-day

adjustments because the reporting periods of the various utilities are not
the same. A leap year adjustment is also made where appropriate.
