Industrial Production
Coverage. The industrial production (IP) index measures output in the manufacturing, mining, and electric and gas utilities industries; the reference for the index is 1992. For the period since 1992, the total IP index has been constructed from 264 individual series based on the 1987 Standard Industrial Classification (SIC). These individual series are classified in two ways: (1) m groups, such as consumer goods, equipment, intermediate products, and materials; and (2) industry groups, such as two-digit SIC industries and major aggregates of these industries-for example, durable and nondurable manufacturing, mining, and utilities.
Market groups. For purposes of analysis, the individual IP series are grouped in final products, intermediate products, and materials. Final products are assumed purchased by consumers, businesses, or government for final use. Intermediate products are expected to become inputs in nonindustrial sectors, such as construction, agriculture, and services. Materials are industrial output requiri further processing within the industrial sector. Total products comprise final a intermediate products, and final products are divided into consumer goods and equipment.
Timing. The first estimate of output for a month is published around the 15th of 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 so data become available. (Revised estimates are denoted by the superscript "r" in tables.) After the fourth month, indexes are not revised further until the time annual revision or a benchmark revision. The last three benchmark revisions were published in 1990, 1985, and 1976.
Source data. In annual or benchmark revisions, 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 Department of the Interior; and publications of the Department of Energy. On a monthly basis, the individual indexes of industrial production are constructed f two main types of source data: (1) output measured in physical units and (2) dat inputs to the production process, from which output is inferred. Data on physica products, such as tons of steel or barrels of oil, are obtained from private tra associations as well as from government agencies including those listed above; d of this type are used to estimate monthly IP where possible and appropriate. Whe suitable data on physical product are unavailable, estimates of output are based 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 based on historical relationships between the inputs and the comprehensive data to benchmark the IP indexes; these factors also may be influenced by technologic or cyclical developments. Especially for the first and second estimates for a gi month, the available source data are limited and subject to revision. Weights. In the index, series that measure the output of an individual industry weighted according to their proportion in the total value-added output of all
industries. The industrial production index, which extends back to 1919, is buil annually weighted chain-type index since 1977. The components of IP are combine using estimates of value added per unit of output. For months from January to J the weights are 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. The IP proportions shown in column 1 of tables 1A, and 6 are estimates of the industries' relative contributions to overall growth following year. For example, a 1 percent increase in durable goods manufacturin 1997 would account for an increase in total IP of nearly 1/2 percent.
Seasonal adjustment. Individual series are seasonally adjusted by the X-11 ARIMA method, developed at Statistics Canada. For series based on production-worker hours, the current seasonal factors were estimated with data through October 199 for other series, the factors were estimated with data through at least June 199 some cases, series were preadjusted for the effects of holidays or the business before using X-11 ARIMA. For the data since 1977, all seasonally adjusted aggregate indexes are calculated by aggregating the seasonally adjusted indexes the individual series.
Reliability. The average revision to the level of the total IP index, without r sign, between the first and the fourth estimates was 0.28 percent during the 198 period. The average revision to the percent change in total IP, without regard from the first to the fourth estimates was 0.21 percentage point during the 1987 period. In most cases (about 81 percent), the direction of change in output ind by the first estimate for a given month is the same as that shown by the fourth 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. ********* ********* ********* ********* ********* ********* *********
