Industrial Production and Capacity Utilization: The 2009 Annual Revision


Anne Hall, of the Board's Division of Research and Statistics, prepared this article. Deepti Iyer provided research assistance.

On March 27, 2009, the Federal Reserve published revisions to its index of industrial production (IP) and the related measures of capacity and capacity utilization. Although the revision affected the data from January 1972 through February 2009, most of the changes were for the period beginning in 2004.1 The overall contour of total IP is little changed by the revision. Industrial output rose steadily at an average annual rate of 2.3 percent from 2004 through 2007, then fell sharply in 2008 at a rate of negative 6.7 percent (table 1). Measured from fourth quarter to fourth quarter, the increase in total IP in 2007 is now reported to have been 0.3 percentage point less, and the decrease in total IP in 2008 is now reported to have been 0.6 percentage point more, than earlier estimates.2

The revision shows that the rates of capacity utilization for total industry in the fourth quarters of 2007 and 2008 were both about 1/2 percentage point lower than previously estimated. Utilization in 2007 was 80.4 percent, about 1/2 percentage point below its long-run (1972 through 2008) average, and, in 2008, it was 74.2 percent, 6.7 percentage points below its long-run average. The operating rate for manufacturing was revised down 0.6 percentage point in 2007 and 0.8 percentage point in 2008; for the fourth quarter of 2008, the factory operating rate stood at 70.9 percent, 8-3/4 percentage points below its long-run average.3 The utilization rate for mines was revised down about 1/2 percentage point in 2006 but was little revised in other years; at the end of 2008, it stood at 89.6 percent, about 2 percentage points above its long-run average. The operating rate for utilities was revised down 0.7 percentage point in both 2006 and 2007; in 2008, it was revised down 0.6 percentage point, to 83.6 percent, and was 3.2 percentage points below its long-run average.

Compared with the previous estimates, total industrial capacity is now reported to have risen 0.4 percentage point less in 2008 and is expected to fall 0.6 percentage point more in 2009. The smaller increase in 2008 reflected a substantial downward revision to capacity in the high-technology manufacturing industries; the capacity indexes for mining, for utilities, and for manufacturing outside of the high-technology industries are all now reported to have been higher in 2008 than stated previously. The larger decrease in total industrial capacity in 2009 reflects downward revisions to the indexes for both durable and nondurable manufacturing and for mining; the capacity indexes for other manufacturing (logging and publishing) and utilities were little changed from their previous estimates.

Although comprehensive benchmark production data for manufacturing for 2007 are not yet available, the updated measures of production incorporate several newly available sources of data. Estimates of manufacturing (NAICS) production were updated with data from selected 2007 Current Industrial Reports (CIRs) from the U.S. Census Bureau. Estimates of other manufacturing (logging and publishing) were updated with annual data on logging for 2007 from the U.S. Forest Service and with annual data on the publishing industry from the Census Bureau's Service Annual Survey. The index for mining was updated with new annual data on mineral extraction for 2006 and 2007 from the U.S. Geological Survey (USGS). The weights that allocate individual production indexes into multiple market groups were previously derived from the benchmark input-output accounts for 1997 from the Bureau of Economic Analysis (BEA); with this revision, these weights were updated using data from the benchmark input-output accounts for 2002.4 Updated price deflators from the BEA were used in the construction of the revised production estimates. Finally, the new monthly production estimates also reflect the incorporation of updated seasonal factors and monthly source data that became available (or were revised) after the closing of the reporting window. The results of both the 2007 Census of Manufactures and the 2008 Annual Survey of Manufactures (both from the Census Bureau) should be available for the 2010 revision to the IP indexes.

Results from the Census Bureau's Quarterly Survey of Plant Capacity for the fourth quarters of 2007 and 2008 were used to update the capacity indexes and capacity utilization rates. In addition, the revisions to the capacity indexes and capacity utilization rates incorporate the revised production indexes and newly available data on industrial capacity from the USGS, the Energy Information Administration of the U.S. Department of Energy (DOE), and other organizations.

Results of the Revision

As revised, total IP for the fourth quarter of 2008 was 104.4 percent of output in 2002, and capacity stood at 140.7 percent of output in 2002. Both indexes are lower than reported previously. The capacity utilization rate for total industry in the fourth quarter of 2008 was 74.2 percent, 0.7 percentage point below what was stated earlier. Detailed results of the revision can be found in the appendix tables.5

Industrial Production

The overall contour of IP in this revision is similar to that reported previously (figure 1). The total index rose modestly each year from 2004 through 2007 and then dropped in 2008. Relative to the previous estimates, total IP increased 0.3 percentage point less in 2007 and fell 0.6 percentage point more in 2008. Revisions to the changes in other recent years were smaller. The change in total IP was revised down 0.1 percentage point in 2004 and was revised up 0.1 percentage point in 2006; it was not revised noticeably in 2005.

Market Groups

Although the aggregate index for IP was little revised before 2007, revisions to the indexes for some market groups were significant. These revisions largely resulted from the incorporation of the 2002 benchmark input-output accounts from the BEA, which, as discussed further in the section on technical aspects of the revision, updated the weights used to allocate individual production indexes to multiple market groups.

The production index for final products and nonindustrial supplies follows an output path similar to that for total IP; moderate gains in 2004 through 2007 were followed by a drop in 2008 (figure 2 and table A.3). Compared with the previous estimates, the index for final products and nonindustrial supplies is now reported to have advanced 0.5 percentage point less in 2007 and to have decreased 0.4 percentage point more in 2008. Overall changes to the rates of increase in other years were minimal; the change in the index was revised down 0.1 percentage point in 2004 and was essentially unrevised in 2005 and 2006.

The change in the output of consumer goods was revised down 1 percentage point in 2007; revisions to other years were small. The output of durable consumer goods declined in 2004 and 2006, rose slightly in 2005 and 2007, and dropped sharply in 2008. The rates of change are now higher than earlier estimates suggested in 2004 and in 2006 through 2008, and they are a touch lower in 2005 than previously reported. Among durable consumer goods, the most significant revisions were in the index for home electronics, which now is estimated to have increased less rapidly in 2005 and 2006, to have increased more rapidly in 2004 and 2007, and to have posted an advance instead of a decline in 2008. Elsewhere within durable consumer goods, the index for miscellaneous durable consumer goods is now estimated to have increased less rapidly in 2005, and to have decreased less rapidly in 2006, than previously reported. Revisions to the indexes for the other major categories of durable consumer goods were smaller.

The index for consumer nondurables shows moderate gains in output in 2004 through 2006, but, with this revision, it now posts a decline instead of an advance in 2007. The index also drops slightly in 2008. Revisions in recent years besides 2007 were small. Among consumer nondurables, the changes in the index for clothing were revised down for 2004 through 2006 and revised up for 2007 and 2008. The index for chemical products, which was previously flat in 2007 and declined slightly in 2008, now moves down significantly in both years. The index for paper products was revised up for 2005 and 2006, revised down for 2004 and 2007, and stood below its previous level for the fourth quarter of 2008. The index for consumer energy products was revised up in 2008 and posted moderate increases, on net, over the past few years.

The production of business equipment increased solidly from 2004 through 2006, rose slightly in 2007, and then fell in 2008. Relative to previous estimates, the rates of change in the index were noticeably lower in 2005 and 2007; the revisions to the data for other recent years were smaller. For transit equipment, output rose substantially, on net, from 2004 through 2006 and decreased in 2007; the index plummeted in 2008, partly because of weakness in the motor vehicle industry and partly because of a strike at a major aircraft producer in the second half of the year. Although the rates of change in the index for transit equipment were revised down in 2004, 2005, and 2008 and were revised up in 2007, the level of output at the end of 2008 was nearly the same as reported previously. The production of information processing equipment is now estimated to have expanded less rapidly over the past few years than reported earlier, and the production of industrial and other equipment in 2007 and 2008 appears slightly weaker. The production of defense and space equipment is now higher than estimated previously in 2005 through 2008.

After posting gains in 2004 and 2005, the output of construction supplies decreased moderately in 2006 and 2007 and then dropped sharply in 2008. The revisions to this index were relatively small, and its level in the fourth quarter of 2008 is nearly the same as reported earlier. The production of business supplies rose modestly from 2004 through 2007 and then slumped in 2008; the rates of change are higher than reported earlier for 2005 through 2007 but are lower for 2004 and 2008.

The production of materials expanded over the years 2004 through 2007, then fell markedly in 2008; the rates of change for this index are little revised before 2008, but the drop in 2008 is larger than estimated previously. The indexes for durable and nondurable materials both fell more than 10 percent in 2008 after having increased moderately, on net, from 2004 through 2007. The production of durable materials is now estimated to have risen more slowly in 2006 and 2007 and to have fallen more quickly in 2008. These revisions were due in large part to revisions to the index for equipment parts. For nondurable materials, the output gains in 2006 and 2007 are now higher than stated earlier, largely because the declines in textile materials in those years are now not as steep as previously reported and the increases in chemical materials in the same years were revised up. The index for energy materials edged up in 2008 after having increased moderately in the previous two years, and it is little changed by the revision.

Production by Industry Group

Manufacturing production expanded each year from 2004 through 2007 and then slumped in 2008 (figure 3 and table A.3). The output of manufacturing advanced less in 2007, and contracted more in 2008, than reported earlier. With this revision, the month of the peak in manufacturing production moved from July 2007 to December 2007.

For durable goods industries as a whole, output rose in each year from 2004 through 2007 and fell sharply in 2008. Revisions to the index for durable goods industries for the past few years were small on net. Among durable goods industries, most major categories followed contours similar to that of the durable goods aggregate, with net increases from 2004 through 2007 followed by sharp drops in 2008. Notable exceptions were wood products, nonmetallic mineral products, motor vehicles and parts, and furniture and related products; the indexes for these categories started trending down before 2008.

The revisions to the changes in the output of most major categories of durable goods before 2007 were slight; exceptions include computer and electronic products, in which the gain in output in 2006 is now stated to have been significantly lower, and aerospace and miscellaneous transportation equipment, in which the gain in output in 2006 is now stated to have been somewhat higher. For 2007, the output indexes were revised down noticeably for wood products, nonmetallic mineral products, computer and electronic products, and furniture and related products but were revised up for miscellaneous manufacturing. For 2008, relative to previous estimates, higher output indexes are reported for electrical equipment, appliances, and components and for furniture and related products, but the production indexes for wood products, primary metals, machinery, computer and electronic products, and motor vehicles and parts were revised down moderately.

Production in nondurable manufacturing industries followed a contour similar to that of durable manufacturing, with advances in every year from 2004 through 2007 followed by a decline in 2008. Neither the overall advance in the earlier years nor the decline last year was as great as the swings in durable manufacturing. The output index for the nondurable goods sector in most recent years was little revised, on net, compared with previous estimates. The current revision reports noticeably higher rates of change in 2007 in textile and product mills, apparel and leather, and petroleum and coal products but a noticeably lower rate of change in chemicals. For 2008, output is now reported to have fallen markedly faster for textile and product mills, apparel and leather, printing and support activities, chemicals, and plastics and rubber products compared with previous estimates.

The revised output index for other manufacturing (logging and publishing) fell each year from 2005 through 2008, with a particularly sharp drop in 2008. Output in these industries is now estimated to have decreased substantially less in 2006 than reported earlier, but revisions to the rates for other years were smaller.

The index for mining rose moderately in the past two years after a jump in 2006; the increase in 2006 was revised up relative to previous estimates, but the index is otherwise similar to what was previously reported. For utilities, the revised output estimates are also, in general, very similar to those reported earlier.

The estimates for selected high-technology industries--computers and peripheral equipment, communications equipment, and semiconductors and related electronic components--were revised significantly over the 2004-08 period (figure 4 and table A.4). On net, output in the high-tech sector is still reported to have posted gains in recent years, with robust increases from 2004 through 2007 followed by a contraction in 2008. However, the increases in 2006 and 2007 are now shown to have been slower, and the decrease in 2008 is now shown to have been steeper, than reported earlier.

Among the major high-tech components, production of computers and peripheral equipment rose solidly in each of the years from 2004 through 2007 and then fell in 2008; the rates of change were revised up in each of the past few years except 2005. The output of communications equipment expanded in each of the past few years, but the rates of increase in most years are markedly lower than estimated previously. Most notably, the increase of 20.6 percent that was reported earlier for 2007 has been revised down to 6.6 percent based on shipments data from the CIR for telecommunications. Production of semiconductors and related components rose solidly from 2004 through 2007 but contracted significantly in 2008. The expansion in production from 2004 through 2007 was considerably less than stated earlier, and the slight decline previously estimated for 2008 has been revised down to a significant decrease.

Capacity

Total industrial capacity is estimated to have risen at an average annual rate of 1.4 percent in 2005 through 2008 (table A.6). The average annual rate is the same as previous estimates, but the rates of change in 2006 and 2007 are slightly higher, and the rate of change in 2008 is somewhat lower, than stated previously. In 2009, total industrial capacity is now expected to decline nearly 1 percentage point; this decline is larger than estimated previously.

The contour of manufacturing capacity and the revisions to that contour are similar to those for total industry. Manufacturing capacity is now shown to have expanded at an average annual rate of about 1.6 percent from 2005 through 2008, about 0.1 percentage point less than estimated earlier. In 2009, manufacturing capacity is now expected to contract 1.2 percent.

Within manufacturing, the capacity of durable goods manufacturers expanded moderately in each year from 2005 through 2008 and is expected to contract somewhat in 2009. The increase in 2008 was tempered considerably by the recent revision. The capacity of nondurable goods manufacturers followed a similar contour to that of durable goods manufacturers, but the increases from 2005 through 2008 were smaller, and the decline in 2009 steeper. Nondurable goods manufacturing capacity is expected to decrease more in 2009 than in previous estimates; rates of change in capacity for most major nondurable industry groups were marked down. Capacity for the logging and publishing industries rose, on net, from 2005 through 2008 but is expected to fall in 2009; the rates of change are higher as a result of the revision.

Aggregate capacity for the selected high-technology industries advanced substantially in each year from 2005 through 2008 and is expected to expand appreciably in 2009. Relative to previous reports, capacity in these industries rose less quickly in 2005, 2006, and especially 2008, but it increased somewhat more rapidly in 2007. It is expected to rise faster in 2009 than previously estimated. Excluding high-technology industries, manufacturing capacity expanded slightly from 2005 through 2008 but is expected to decline in 2009. The current estimates are similar to previous reports except for 2009, during which the contraction in capacity is now anticipated to be greater than stated previously.

Capacity at mines is estimated to have fallen in 2005 and to have expanded from 2006 through 2008; it is expected to recede somewhat in 2009. The gains in 2006 and 2008 are now reported to have been larger than previously published, but the increase in 2007 has been revised down, and capacity at mines is now expected to contract rather than expand in 2009. Capacity at electric and gas utilities has risen each year since 2004. The current estimates show larger gains in 2005 and 2006 than reported earlier; revisions to other recent years were negligible.

By stage of processing, capacity in the crude stage is now reported to have risen more in 2006 and 2008 than previously shown but is now expected to fall in 2009. The rates of change for capacity in the primary and semifinished stages were revised down for 2008 and 2009; revisions to earlier years were slight. Relative to previous estimates, increases to the index for finished goods processors were revised up in 2007 and 2008, but capacity is expected to fall more in 2009 than stated previously.

Capacity Utilization

From 2005 through 2007, the capacity utilization rate for total industry stood a little below its long-run average of 80.9 percent, but in 2008 it fell to 74.2 percent, a level 6.7 percentage points below its long-run average (table A.7). The utilization rate for total industry was revised down about 1/2 percentage point in 2007 and 0.7 percentage point in 2008; revisions for earlier years were smaller.

Similarly, manufacturing capacity utilization, on balance, spent most of 2005 through 2007 at a little below its long-run average of 79.6 percent. The utilization rate in manufacturing tumbled during 2008, reaching 70.9 percent in the fourth quarter of 2008, 8-3/4 percentage points below its long-run average. Relative to earlier reports, the factory operating rate was revised down in 2007 and 2008 but was little changed in earlier years. Within durable goods, utilization rates for many industries were near their long-run averages from 2005 through 2007 and then dropped well below average in 2008; among the exceptions were motor vehicles and parts, nonmetallic mineral products, and wood products, in which the utilization rate was significantly below average in 2006 and 2007 and then fell even further in 2008. In the fourth quarter of 2008, three durable goods industries (nonmetallic mineral products, primary metals, and furniture and related products) had utilization rates between 10 and 20 percentage points below their long-run averages, and two durable goods industries (wood products and motor vehicles and parts) had utilization rates more than 20 percentage points below their long-run averages.

Among durable goods industries, nonmetallic mineral products had the largest downward revisions to utilization over the 2005-08 period; other industries with large downward revisions to their capacity utilization rates were wood products and motor vehicles and parts. The durable goods industries that reported the largest net upward revisions since 2005 were machinery, aerospace and miscellaneous transportation equipment, and furniture and related products.

Utilization rates for many nondurable goods industries were somewhat below their long-run averages in 2005 through 2007 and then fell further in 2008, but the declines in 2008 were not as great, on average, as the declines in the utilization rates for durable goods industries. In the fourth quarter of 2008, four nondurable goods industries (textile and product mills, paper, printing and support activities, and plastics and rubber products) had utilization rates between 10 and 20 percentage points below their long-run averages. The nondurable goods industries with the largest downward revisions to utilization rates over the 2005-08 period were food, beverage, and tobacco products; petroleum and coal products; and plastics and rubber products. Apparel and leather had the most noticeable upward revisions to its utilization rate over this period; other nondurable goods industries with large upward revisions were textile and product mills and printing and support activities.

Capacity utilization in the other manufacturing category (logging and publishing) was revised down in 2005 and revised up from 2006 through 2008. It stood more than 10 percentage points below its long-run average in the fourth quarter of 2008.

Capacity utilization in mining was generally above its long-run average from 2006 through 2008 and, in the fourth quarter of 2008, stood at 89.6 percent, about 2 percentage points higher than its long-run average. Relative to earlier estimates, the utilization rate for mining was a little lower in 2006 and 2008 but was little changed in 2005 and 2007. At electric and gas utilities, capacity utilization rates were revised down for 2005 through 2008, and capacity utilization in the fourth quarter of 2008 is now estimated to have been more than 3 percentage points below its long-run average.

The operating rates for the selected high-technology industries were above their long-run averages in the fourth quarters of 2006 and 2007 but fell to more than 8 percentage points below their long-run averages in 2008 (figures 5 and 6 and table A.7). Relative to earlier estimates, capacity utilization is now reported to have been higher in 2005, 2006, and 2008 but lower in 2007. The operating rate for the computers and peripheral equipment industry is now shown to have been higher than previously reported in each of the past few years, particularly 2008, but, in the fourth quarter of 2008, stood about 4 percentage points below its long-run average. The utilization rate for communications equipment was more than 8 percentage points below its long-run average in 2005 and rose to more than 6 percentage points above its long-run average in 2006 before dropping in 2007 and 2008; at the end of 2008, the rate was 1.7 percentage points below its long-run average. Capacity utilization for communications equipment is now higher than previously reported in 2005 and 2006 but lower in 2007 and 2008. Capacity utilization in the semiconductor and related electronic components industry is now lower than earlier estimates in every year after 2005. The operating rate in this industry was above or near its long-run average from 2005 through 2007 but stood more than 16 percentage points below its long-run average in the fourth quarter of 2008.

Technical Aspects of the Revision

Comprehensive benchmark data for manufacturing production in 2007 were not available for this revision. After incorporating the limited information that was available, the benchmark production indexes for manufacturing--defined for each six-digit NAICS industry as nominal gross output divided by a price index--were little changed before 2007. The principal changes resulted from small revisions to price indexes from the Bureau of Economic Analysis and from improved estimates of price indexes for communications equipment output constructed by the Federal Reserve (discussed later in the article). In addition, the benchmark production indexes for other manufacturing (logging and publishing) were advanced through 2007 and updated for 2006 based on data from the Forest Service and the Census Bureau.

The IP indexes in recent years incorporated information from selected CIRs for 2007 from the Census Bureau, the revised benchmark input-output accounts for 2002 from the BEA, the Quarterly Survey of Plant Capacity from the Census Bureau for 2007 and 2008, and other annual industry reports. The indexes also incorporated revised monthly and quarterly source data on production, shipments, inventories, and production-worker hours.

As mentioned earlier, the benchmark production indexes for most industries incorporate updated price indexes from the industry output program of the BEA. However, the price indexes for pharmaceuticals (NAICS 325412), for semiconductors (NAICS 334413), and for most components of communications equipment (NAICS 3342) are constructed by the Federal Reserve from alternative sources. This article provides annual and quarterly price indexes for the relevant components of communications equipment, along with quarterly semiconductor price indexes (tables A.9, A.10, and A.11).

Changes to the Methodology for Adjusting for Temporary Help Supply Employees

The compilation of the initial IP estimate for a given month relies heavily on the hours worked by production workers in the manufacturing sector when the availability of the other IP source data is limited. The hours data are adjusted to account for the labor input of temporary help supply (THS) employees who work in the manufacturing sector; this adjustment is necessary because these workers are on the payrolls of companies that are classified in the service sector of the economy by the Bureau of Labor Statistics. These adjusted detailed hours series are used in making (1) estimates for those IP series based on labor input for the period for which benchmark output indexes are not yet available and (2) preliminary estimates of those IP series based on physical product data for which the current source data are not yet available.

The procedure for implementing this adjustment is as follows. An estimate is made of the component of THS employment that is allocated to manufacturing. This estimate begins with a baseline figure projected from the Current Population Survey but varies based on the cyclical movements of the manufacturing sector and the rest of the economy--THS employment has a cyclical pattern similar to that of manufacturing.6

The THS employment in manufacturing is then allocated among the NAICS three-digit industries based on each industry's use of THS workers as reported in the Census Bureau's Annual Survey of Plant Capacity (ASPC) and on each industry's cyclical patterns. With this revision, the allocation of THS employment among industries within manufacturing was updated based on data from the ASPC for 2002 through 2005.7

In addition, this revision updates the method for estimating each industry's monthly baseline share of temporary help employment use in manufacturing. Previously, this share was held constant for each industry at the level estimated according to the method just described. With this revision, the share is allowed to evolve based on the industry's share of total manufacturing employment. THS employment is multiplied by assumptions on hours worked and on the productivity of a THS worker relative to a permanent worker to estimate the effective hours contributed by THS workers for each three-digit manufacturing industry. The THS hours are added to the reported production-worker hours for each industry to produce an adjusted production-worker hour series. The percentage adjustment for each three-digit industry's hours is then applied to the hours series for each of its component industries.

Estimating the Effect of Hurricanes on Production

Industrial production in the United States was severely affected by hurricanes in both 2005 (Hurricanes Katrina and Rita) and 2008 (Hurricanes Gustav and Ike). Industries with a large presence in the Gulf Coast region include oil and natural gas extraction, petroleum refining, petrochemical manufacturing, and plastic resin manufacturing. These industries were mostly shut down during the storms, and storm damage sometimes delayed their return to operation. In addition, some other industries in the afflicted areas also shut down factories. The data on which the IP indexes are based for many of these industries are not available on a timely basis; initial estimates for them were made from other sources. The estimation of crude oil extraction and petroleum refining output was relatively straightforward with the availability of weekly data from the Department of Energy. Timely output data on natural gas extraction were less available, but reports by the Minerals Management Service of the U.S. Department of the Interior on shut-in capacity provided a good first estimate until data on output became available from the DOE. Weekly data on railcar loadings of chemicals from the Association of American Railroads and information on shut-in capacity of petrochemical plants from Chemical Market Associates, Inc., and PetroChem Wire were used to inform the IP estimates for petrochemical manufacturing; reports from the National Petrochemical and Refiners Association on quarterly petrochemical output became available later and improved the estimates. Anecdotal information from contacts in the plastic resin industry on output was used until monthly data on production from the American Chemistry Council became available. The effect of the storms on other industries was estimated based on data on the regional distribution of industrial activity from the County Business Patterns report of the Census Bureau.

Estimation of Capacity in the Light Motor Vehicle Industry

Capacity for light duty motor vehicles (NAICS 33611) is expected to contract significantly in 2009. The estimate for motor vehicle assembly capacity for a year is constructed from estimates of the peak historical assembly-line speed over the previous 10 years and the number of hours that can be worked at each plant in the United States. Annual line speed data and the number of shifts at individual plants are reported in Ward's Automotive Yearbooks. An annual capacity count for a plant is calculated by multiplying the peak line speed by the hours per year that the plant could run. New plants are added to capacity when they start production, and plants are removed from capacity when they are permanently shuttered. An adjustment is made to reflect manufacturers' plans to open or close assembly plants only when the dates have been confirmed and specific plants have been named. Plant-level data are aggregated using price weights for the different models of light vehicles, and if a plant produces multiple models on one assembly line, capacity is split among models based on estimated production levels for the models at the plant.

Changes to Individual Production Series

With this revision, the monthly production indicators for some series have changed.

Carpet and Rug Mills

The index for carpet and rug mills (NAICS 31411) is based on quarterly data on unit shipments from the Carpet and Rug Institute with a model-based inventory adjustment.8 Formerly, it was based on monthly data from the same source. A cubic spline is used to interpolate monthly values from the quarterly figures, a method similar to that used for the other series for which only quarterly physical product data are available.9

High-Technology Goods

Communications equipment

Price indexes for two product classes of communications equipment were revised to incorporate additional detail. The price index for enterprise and home voice equipment (part of NAICS 33421) was updated. A price index for telephones and answering machines, one of the two product categories in this industry, was previously calculated using average selling prices for two types of phones (corded and cordless) but is now a matched-model index constructed using detailed data, beginning in 1997, from the Consumer Electronics Association on transmission frequency, number of lines, and presence of other features such as caller identification, speakerphone, and integrated answering machine. The price index for wireless system equipment (part of NAICS 33422), which covers mobile phone infrastructure, was improved by folding in additional detail on base-station radio transmission capacity using data from the Dell'Oro Group, a market research firm. The resulting mobile infrastructure price index fell 4 percentage points faster per year, on average, from 2000 to 2008.

Updated price indexes for the six product groups in communications equipment, introduced in the 2008 revision, are included in this article (table A.9).

Computers

With this revision, a change to the method for estimating the domestic shipments share of domestic absorption in electronic computer manufacturing (NAICS 334111) was introduced. The six product-based indexes for computer manufacturing are derived from quarterly data on nominal domestic absorption from IDC, an industry research group. For each product, an estimate of the domestic shipments share of domestic absorption--derived from the Census Bureau's CIR for computers and peripheral equipment--is used to convert the IDC domestic absorption data to a domestic shipments concept.10

The domestic shipments share for each of the six indexes was constructed by dividing the relevant annual measure of domestic product shipments from the CIR by the corresponding measure of annual domestic absorption from IDC. Each of these shares is converted to a quarterly frequency and projected forward for more-recent quarters when the CIR data are not yet available. Prior to the current revision, projections of the individual domestic shipments shares were based on monthly data on foreign trade in computers from the Census Bureau. Specifically, domestic absorption for the industry (NAICS 334111) was adjusted by net exports to obtain domestic shipments; the change in the ratio of domestic shipments to domestic absorption was applied to the shipments share for each of the six product indexes. With the current revision, the foreign trade data are no longer used. Instead, the CIR-based individual domestic shipments shares are extended out with a model-based trend for quarters when the annual CIR data are not yet available. Examination of all relevant data sources suggests that the shares derived from model-based trends lead to more-accurate measures of domestic production than the shares derived from trade data.

Semiconductors

Beginning with the 2008 revision, detailed price data on MOS (metal-oxide semiconductor) memory products (part of NAICS 334413) from iSuppli, an industry research group, have been used to construct quarterly indicator quality-adjusted price indexes for three categories--DRAM (dynamic random access memory), flash memory, and other memory. These prices are included in this article (table A.11).

Civilian Aircraft

With this revision, a change to the methods used for the calculation of the index of industrial production for civilian aircraft (part of NAICS 336411) was introduced. Production in the civilian aircraft industry is estimated by combining data on aircraft deliveries with an assumption about the time required to build a plane and the intensity of activity during that period. Previously, the production index for aircraft was based on a 10-month build period, during which 43 percent of production was assumed to have occurred in the three months immediately before the delivery and 57 percent was assumed to have occurred in the seven preceding months. Based on discussions with contacts in the aircraft industry, the new indexes assume a shorter build period. Specifically, they now assume that commercial aircraft take either two or three months to build. The new assumptions were applied to the entire history of aircraft models that are still in production; the data for models that are no longer in production were left unrevised.

Changes to Individual Capacity Series

Electricity Generation

The capacity index for electric power generation, transmission, and distribution (NAICS 2211) is now based on generation capability data from the DOE; previously it was based on electricity generation capacity data from the North American Electric Reliability Corporation (NERC). The change was made because the DOE data are compiled using a more consistent definition over time. However, because the DOE data are published with a lag, the capacity projection for the most recent year or two is estimated by extending the DOE generation capability series by the rate of change shown for the NERC electricity generation capacity data.

Nonferrous Metals (except Aluminum)

The capacity index for nonferrous metal (except aluminum) production and processing (NAICS 3314) is now based on copper smelting, copper refining, and zinc smelting data from the U.S. Geological Survey. Formerly the capacity index was based on the USGS data on just copper smelting and copper refining.

Natural Gas Extraction

The DOE no longer publishes physical capacity estimates for natural gas extraction (part of NAICS 211111). Capacity estimates for recent years are based on trend-through-peak estimates of capacity using the IP index and output projections from the Short-Term Energy Outlook (STEO) and Annual Energy Outlook (AEO) reports of the DOE.

Trend-through-Peak Estimates

As with recent years for natural gas extraction, the trend-through-peak method of estimating capacity is also used for those industries in mining and utilities for which no physical capacity sources are available--seven individual series accounting for about 5 percent of capacity. With this revision, the trend-through-peak method used to estimate capacity indexes for oil extraction (part of NAICS 211111), natural gas liquid extraction (NAICS 211112), and natural gas sales and transmission (NAICS 2212) is based on production indexes that are extended using output projections from the STEO and AEO reports.

The basic method in estimating trend-through-peak capacities for these industries is to construct baseline estimates of capacity by connecting peaks in production, with these peaks representing 100 percent utilization. In practice, the procedure involves a fair degree of judgment and deviates from a strict trend-through-peak approach in a variety of ways. First and most important, if a peak in production was reached several years ago and production has not subsequently approached that previous maximum, published capacity levels generally will, after a time, trend downward. That is, they will tend to follow recent IP. Second, the capacity levels corresponding to peaks in production for different series have yielded a variety of peak utilization rates historically.

Weights for Aggregation

The aggregation method for the IP index is a version of the Fisher ideal index formula.11 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.12 The weights for manufacturing industries are derived from value-added measures from the Census of Manufactures and the Annual Survey of Manufactures. The Federal Reserve derives estimates of value added for the electric and gas utility industries from annual revenue and expense data issued by other organizations. The weights for aggregation, expressed as unit value added, were estimated with the latest data on producer prices for the period after 2006. Table A.8 shows the annual value-added proportions in the IP index from 2001 through 2008.

The outputs of most industries are inputs to multiple markets. Although data that directly split the output of an industry by its purchaser are sometimes available, most industry output measures do not provide that detail. With the 2002 annual revision, weights that allocate individual IP indexes into multiple market groups were derived from the Standard Make and Use Tables (at the detailed level) from the 1997 benchmark input-output accounts of the BEA.13 With this revision, the weights for 2002 were updated using estimates from the same tables from the 2002 input-output accounts; years subsequent to 2002 were assumed to have weights identical to those for 2002. The weights for the period up through 1997 are still computed from the 1997 accounts, and the weights between 1997 and 2002 are linear combinations of the 1997 and 2002 weights.

Revised Monthly Data

This revision incorporates product data that became available or were revised after the regular six-month reporting window for monthly IP was closed. These data were released with too great a lag to be included with monthly IP estimates but were available for inclusion in the annual revision.

Revised Seasonal Factors

Seasonal factors for all series were reestimated using data that extend into 2008 or 2009. Factors for production-worker hours--which adjust for timing, holiday, and monthly seasonal patterns--were updated with data through February 2009. The updated factors for the physical product series, which include adjustments for holiday and workday patterns, used data through 2008. Seasonal factors for unit motor vehicle assemblies have been updated, and projections through September 2009 are on the Federal Reserve Board's website.

Note: Charles Gilbert directed the 2009 revision and, with Kimberly Bayard, David Byrne, Norman Morin, and Daniel Vine, prepared the revised estimates of industrial production. Norman Morin and Daniel Vine prepared the revised estimates of capacity and capacity utilization.

1. When necessary to maintain consistency with any revisions to the data for 1972 and subsequent years, the levels of the production and capacity indexes for the years before 1972 were multiplied by a constant. However, utilization rates and rates of change in IP for the years before 1972 were not revised.  Return to text

Note: The IP proportion data are estimates of the industries' relative contributions to the overall IP change between the reference year and the following year. For example, a 1 percent increase in durable goods manufacturing between 2008 and 2009 would account for a .381 percent increase in total IP.

1. North American Industry Classification System.  Return to table

2. Manufacturing comprises North American Industry Classification System (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 industries 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.Return to table
