nondurable consumer goods fell in September. Among durables, home electronics dropped 3.0 percent and was
19.1 percent below its level in September 2000. The output of automotive products also fell about 3 percent, while the
other major categories of consumer durables registered smaller declines. Nondurable consumer goods, which slipped
0.3 percent, showed declines in all categories except paper products, which increased 0.4 percent.
The production of business equipment dropped 2.3 percent in September; for the third quarter as a whole, it
tumbled 13.4 percent at an annual rate, its largest quarterly decline since the fourth quarter of 1982. All major categories
declined in September; the output indexes for transit equipment and for industrial and other equipment have contracted
nearly 12 percent in the past twelve months. The production of defense and space equipment, which ticked up
0.2 percent in September, was 3.6 percent above its September 2000 level.
The output of construction supplies decreased 0.6 percent in September, while the output of business
supplies fell 1.5 percent; a sharp cutback in jet fuel production, which was related to the reduction in air traffic,
contributed importantly to the drop for business supplies. The production of industrial materials declined 0.9 percent,
with a large drop in durable goods materials and little change, on balance, in either nondurable or energy materials. For
the third quarter as a whole, production of industrial materials fell at an annual rate of 6.4 percent.
Industry Groups
Manufacturing output fell 1.1 percent in September and the weakness was widespread among industries. In
the third quarter, manufacturing declined at an annual rate of 6.6 percent, after having fallen at a 5.1 percent rate in the
second quarter. The overall production both of durable and nondurable goods decreased in the third quarter; output rose
during the quarter in only two industries—motor vehicles and parts and lumber and products. Among durable goods, the
largest third-quarter declines were in machinery, especially the high-technology industries (computers, communications
equipment, and semiconductors). Also down notably were furniture and fixtures, primary metals, aerospace and
miscellaneous transportation equipment, and miscellaneous manufacturing. Among nondurables, declines were largest in
apparel products, textile mill products, petroleum products, printing and publishing, and paper and products. In
September, all major industry groups in manufacturing were below year-ago levels. The overall factory operating rate
declined about 1 percentage point, to 73.8 percent, a level 7.3 percentage points below the 1967–2000 average.
A 0.3 percent increase in the production at mines retraced the August decline; the utilization rate at mines
rose 0.3 percentage point, to 89.3 percent, a level about 2 percentage points above its 1967–2000 average. The output of
utilities fell back 1.8 percent in September; at 85.7 percent, the operating rate at utilities was about 2 percentage points
below its long-term average.

Revision of Industrial Production and Capacity Utilization
On November 27, the Federal Reserve Board will publish revisions to the index of industrial
production (IP), to the related measures of capacity and capacity utilization, and to the index of industrial
use of electric power. The updated measures will reflect the incorporation of newly available, more
comprehensive source data typical of annual revisions. The new source data are for recent years, primarily
1999 and 2000, although data from 1992 onward will be subject to revision.
Industrial production and capacity utilization will continue to be based on the 1987 Standard
Industrial Classification (SIC) until the 2002 annual revision, after which they will be constructed from the
North American Industrial Classification System (NAICS). The new NAICS-related production indexes
will be based on annual output measures that are constructed by reclassifying the establishments in historical
Censuses of Manufactures and Mineral Industries under NAICS; annual output indexes constructed this way
will maximize the reliability and historical consistency of the IP industry detail.
The updating of source data for IP in the 2001 annual revision will include annual data from the
1999 Bureau of the Census Annual Survey of Manufactures and from selected editions of its 1999 and 2000
Current Industrial Reports. Annual data from the U.S. Geological Survey regarding metallic and
nonmetallic minerals (except fuels) for 1999 and 2000 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 to seasonal factors.
Capacity and capacity utilization will be revised to incorporate preliminary data from the 2000
Survey of Plant Capacity of the Bureau of the Census, which covers manufacturing, along with other 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 some data from the 1997 Census of Manufactures and the
1998 and 1999 Annual Survey of Manufactures.
Once the revision is published, it will be made available on the Board’s web site
(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).

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.

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
1977. Between 1977 and 1992, the weights for months from January to
June were drawn from the year containing the month being estimated and
the preceding year; for months from July to December, the weights are
drawn from the current and following year. Since mid-1992, the weights
change monthly, eliminating distortions in the contributions of several
high-technology industries—sectors where weights shift noticeably
year-to-year. Thus, the current formula for the growth in monthly IP (or
any of the sub-aggregates) since mid 1992 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:

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 1992. For the period since 1997, the total
IP index has been constructed from 276 individual series based on the
1987 Standard Industrial Classification (SIC) 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 intermediate products (which are inputs to nonindustrial
sectors). Materials are inputs in the manufacture of products. Major
industry groups include two-digit SIC 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 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 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 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 
 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 48 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:

1. Includes provisional series totaling nearly 13 percent of IP that are
derived from weekly data and for which the actual data may lag several
months.
2. Includes quarterly data totaling 6 percent of IP that, on average, are
received for the third estimate of industrial production. Specifically, 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.
3. This figure refers only to those individual series that both initially and
ultimately are based on the hours data.

4. Estimates for series not yet covered by data for physical product or
electric power use.
5. Includes monthly and quarterly physical product data totaling 3
percent of IP that typically are available too late for inclusion in the
current index but are included at the time of an annual revision.
Until the source data for a particular series become available for a given
month, estimates for the missing observations are based on other available
data, such as labor input, recent trends in output and orders, and anecdotal
reports from industry sources. After the fourth month that an estimate is
published, indexes are not revised further until the time of an annual
revision or a benchmark revision. These historical revisions are typically
published in the late fall of each year; the most recent revision was
published on December 5, 2000, and incorporated revised source data as
well as data from the 1998 Annual Survey of Manufactures and the 1997
Census of Manufactures.
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 October 2000;
for other series, the factors were estimated with data through at least June
2000. Series are pre-adjusted for the effects of holidays or the business
cycle when appropriate. For the data since 1977, 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 1987–99 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 1987–99 period. In most cases (about 83
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 78 detailed industries (55
in manufacturing, 21 in mining, and 2 in utilities), which mostly
correspond to industries at the two- and three-digit SIC level. Estimates of
capacity and utilization are available for a variety of groups, including
primary and advanced processing industries within manufacturing,
durable and nondurable manufacturing, total manufacturing, mining,
utilities, and total industry. Also, special aggregates are available, such as
high-tech industries and manufacturing excluding high-tech industries.
Component industries of the primary- and advanced-processing groups
within manufacturing are listed in the note on table 2 of the release.
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 15 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

16

account for a bit more than 80 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 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 1967–1999 period, the average total industry
utilization rate is 82.0 percent; for manufacturing, the average factory
operating rate has been 81.1 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 6 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 3-digit SIC level for mining and manufacturing.
Aggregates for 2-digit industries, as well as for total mining, durable,
nondurable, total manufacturing and total industrial electric power use, are
computed. An aggregate showing total industry excluding nuclear
nondefense is shown separately because the value-added proportion for
the nondefense nuclear material series (part of SIC 2819) 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 2- and 3-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 1998 Annual
Survey of Manufactures (the most recent available) suggests the Federal
Reserve data cover about 75 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 3-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 3-digit SIC
industry levels and above. Where reports are late or unavailable for some
reason, responses are estimated.
Seasonal Adjustment. Series are seasonal adjusted at the 3-digit SIC
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.
Description of Tables.
Table 1 summarizes the latest changes in output for the major market and
industry groupings. Fourth-quarter to fourth-quarter changes for the past
three years are shown. Output changes expressed at an annual rate for the
past four quarters as well as monthly changes for the latest four months are
shown. In addition, year-over-year changes are displayed for the latest IP
month.
Table 2, which is in the same format as table 1, summarizes the latest
changes in output for a special group of aggregates that have been
constructed for analytical purposes. The total index is sub-divided into
two broad categories: an energy grouping, which includes consumer
energy products, commercial energy products, energy materials, and oil
and gas well drilling, and a nonenergy grouping, which includes the
remaining portion of the total index. Within the nonenergy aggregate,
several other analytically useful categories are shown. One of these is a
grouping of high-technology industries, which is composed of
semiconductors and related electronic components, and industries that use
a large concentration of these parts—computers and communication
equipment. Other sub-groupings of the market and industry structures
excluding this high-technology grouping and motor vehicles and parts are
shown.
Table 3 displays the last nine months of motor vehicle assemblies, shown
at seasonally adjusted annual rates. Seasonal factors for auto, light truck,
and medium and heavy truck production are available on the Board’s web
site (www.federalreserve.gov/releases/G17/mvsf.html). Monthly
changes in the IP indexes for the corresponding motor vehicle series will
differ slightly from the monthly changes in assemblies, mainly because the
IP indexes are built from a weighted (based on relative values) aggregate
of the individual models.
Tables 4 and 5 show seasonally adjusted indexes for recent months for
the major market and industry groups included on table 1 and the special
aggregates displayed on table 2.
Table 6 summarizes the capacity utilization for the major industry
groupings as well as for a few special aggregates. In addition to the
utilization rates for the most recent four months and four quarters, the
1967–1999 average of utilization rates and operating rates for relevant
cyclical peaks and troughs also are shown for each series.
Table 7 summarizes capacity growth. Average rates of growth in capacity
for selected historical periods and for the most recent five years (on a
fourth-quarter to fourth-quarter basis) are shown. In addition, growth rates
for capacity on a annual-average basis are shown for the latest four
quarters; the capacity growth rate for the current IP month is shown as
well.
Table 8 shows total products expressed in gross values in billions of
chained 1996 dollars at an annual rate. Compiling the IP index using
gross-value weights facilitates comparison with other dollar-based data.
The gross-value system focuses on products that leave the industrial sector
and includes both final and intermediate products. The materials
consumed in making final and intermediate products are implicitly
included in the value weights applied to product series. The gross-product
weights are derived from Census of Manufactures and Annual Survey of
Manufactures data.
Table 9 shows diffusion indexes, which are calculated as the percentage of
IP series that increased over the relevant span (one, three, or six months)
plus one-half of the percentage of series that were unchanged. Because
available source data for the current IP month account for a little less than
half of the total index, the diffusion indexes are published with a
one-month lag.

17

Table 10 shows the most recent six months in index form (both seasonally
and not seasonally adjusted) of electric power use by industry for the
major industry aggregates.
Tables 11–14 display historical seasonally adjusted data for total IP and
manufacturing as well as the aggregates excluding high-technology
industries. Monthly changes in output as well as indexes for output,
utilization, and capacity are shown.
Note: The summary tables in the G17 release do not include all of the
publicly available data. The more detailed series for IP, utilization,
capacity, and electric power are available at the Board’s web site
(www.federalreserve.gov/releases/G17/download.html).
