General CIR Survey Information, Explanation of General Terms

and Historical Note

GENERAL

The CIR program has been providing monthly,

quarterly, and annual measures of industrial activity for

many years. Since 1904, with its cotton and fats and oils

surveys, the CIR program has formed an essential part

of an integrated statistical system involving the quinquennial economic census, manufacturing sector, and

the annual survey of manufactures. The CIR surveys,

however, provide current statistics at a more detailed

product level than either of the other two statistical

programs.

The primary objective of the CIR program is to

produce timely, accurate data on production and

shipments of selected products. The data are used to

satisfy economic policy needs and for market analysis,

forecasting, and decision making in the private sector.

The product-level data generated by these surveys are

used extensively by individual firms, trade associations,

and market analysts in planning or recommending

marketing and legislative strategies, particularly if their

industry is significantly affected by foreign trade.

Although production and shipments information are the

two most common data items collected, the CIR

program collects other measures also such as

inventories, orders, and consumption. These surveys

measure manufacturing activity in important commodity

areas such as textiles and apparel, chemicals, primary

metals, computer and electronic components, industrial

equipment, aerospace equipment, and consumer

goods.

The CIR program uses a unified data collection,

processing, and publication system. The U.S. Census

Bureau updates the survey panels for most reports

annually and reconciles the estimates to the results of

the broader-based annual survey of manufactures and

the economic census, manufacturing sector. The manufacturing sector provides a complete list of all

producers of the products covered by the CIR program

and serves as the primary source for CIR sampling.

Where a small number of producers exist, CIR surveys

cover all known producers of a product. However, when

the number of producers is too large, cutoff and

random sampling techniques are used. Surveys are

continually reviewed and modified to provide the most

up-to-date information on products produced. The CIR

program includes a group of mandatory and voluntary

surveys. Typically the monthly and quarterly surveys are

conducted on a voluntary basis. Those companies that

choose not to respond to the voluntary surveys are

required to submit a mandatory annual counterpart

corresponding to the more frequent survey.

NORTH AMERICAN INDUSTRY CLASSIFICATION

SYSTEM (NAICS), 1997 

The adoption of the North American Industry

Classification System (NAICS) in the 1997 Economic

Census has had a major impact on the comparability of

current and historic data. Approximately half of the

industries in the manufacturing sector of NAICS do not

have comparable industries in the Standard Industrial

Classification (SIC) system that was used in the past.

While most of the change affecting the

manufacturing sector was change within the sector,

some industries left manufacturing and others came into

manufacturing. Prominent among those that left

manufacturing are logging and portions of publishing.

Prominent among the industries that came into the

manufacturing sector are bakeries, candy stores where

candy is made on the premises, custom tailors, makers

of custom draperies, and tire retreading. The net effect

of the classification changes are such that if the 1997

value of shipments data for all manufacturers were

tabulated on an SIC basis, it would be approximately 3

percent higher.

Listed below are the NAICS sectors:

21 Mining

22 Utilities

23 Construction

31-33 Manufacturing

42 Wholesale Trade

44-45 Retail Trade

48-49 Transportation and Warehousing

51 Information

52 Finance and Insurance

53 Real Estate and Rental and Leasing

54 Professional, Scientific, and Technical Services

55 Management of Companies and Enterprises

56 Administrative and Support and Waste Management

and Remediation Services

61 Educational Services

62 Health Care and Social Assistance

71 Arts, Entertainment, and Recreation

72 Accommodation and Food Services

81 Other Services (except Public Administration)

(Not listed above are the Agriculture, Forestry,

Fishing, and Hunting sector (NAICS 11), partially covered

by the census of agriculture conducted by the U.S.

Department of Agriculture, and the Public

Administration sector (NAICS 92), covered by the census

of governments conducted by the Census Bureau.)
Current Industrial Reports A-2

The 20 NAICS sectors are subdivided into 96

subsectors (three-digit codes), 313 industry groups

(four-digit codes), and, as implemented in the United

States, 1170 industries (five- and six-digit codes).

FUNDING

The Census Bureau funds most of the surveys.

However, a number of surveys are paid for either fully

or partially by other Federal Government agencies or

private trade associations. A few surveys are mandated,

but all are authorized by Title 13 of the United States

Code.

RELIABILITY OF DATA

Survey error may result from several sources

including the inability to obtain information about all

cases in the survey, response errors, definitional

difficulties, differences in the interpretation of

questions, mistakes in recording or coding the reported

data, and other errors of collection, response,

coverage, and estimation. These nonsampling errors

also occur in complete censuses. Although no direct

measurement of the biases due to these nonsampling

errors has been obtained, precautionary steps were

taken in all phases of the collection, processing, and

tabulation of the data in an effort to minimize their

influence.

A major source of bias in the published estimates is

the imputing of data for nonrespondents, for late

reporters, and for data that fail logic edits. Missing

figures are imputed based on period-to-period

movements shown by reporting firms. A figure is

considered to be an impute if the value was not directly

reported on the questionnaire, directly derived from

other reported items, directly available from

supplemental sources, or obtained from the respondent

during the analytical review phase. Imputation generally

is limited to a maximum of 10 percent for any one data

cell. Figures with imputation rates greater than 10

percent are suppressed or footnoted. The imputation

rate is not an explicit indicator of the potential error in

published figures due to nonresponse, because the

actual yearly movements for nonrespondents may or

may not closely agree with the imputed movements.

The range of difference between the actual and

imputed figures is assumed to be small. The degree of

uncertainty regarding the accuracy of the published data

increases as the percentage of imputation increases.

Figures with imputation rates above 10 percent should

be used with caution.

DATA REVISIONS

Statistics for previous years may be revised as the

result of corrected figures from respondents, late

reports for which imputations were originally made, or

other corrections. Data that have been revised by more

than 5 percent from previously published data are

indicated by footnotes.

DISCLOSURE

The Census Bureau collects the CIR data under the

authority of Title 13, United States Code, which

specifies that the information can only be used for

statistical purposes and cannot be published or released

in any manner that would identify a person, household,

or establishment. "D" indicates that data in the cell have

been suppressed to avoid disclosure of information

pertaining to individual companies.

EXPLANATION OF GENERAL TERMS

Capacity. The maximum quantity of a product that can

be produced in a plant in 1 day if operating for 24

hours. Includes the capacity of idle plants until the plant

is reported to be destroyed, dismantled, or abandoned.

Consumption. Materials used in producing or

processing a product or otherwise removing the

product from the inventory.

Exports. Includes all types of products shipped to

foreign countries, or to agents or exporters for

reshipment to foreign countries.

Gross shipments. The quantity or value of physical

shipments from domestic establishments of all products

sold, transferred to other establishments of the same

company, or shipped on consignment, whether for

domestic or export sale or use. Shipments of products

purchased for resale are omitted. Shipments of

products made under toll arrangements are included.

Interplant transfers. Shipments to other domestic

plants within a company for further assembly,

fabrication, or manufacture.

Inventories. The quantity or value of finished goods,

work in progress, and materials on hand.

Machinery in place. The number of machines of a

particular type in place as of a particular date whether

the machinery was used for production, prototype, or

sampling, or was idle. Machinery in place includes all

machinery set up in operating positions.

Net receipts. Derived by subtracting the materials held

at the end of the previous month from the sum of

materials used during the current month.

Production. The total volume of products produced,

including: products sold; products transferred or added

to inventory after adjustments for breakage, shrinkage,

and obsolescence, plus any other inventory adjustment;

and products that undergo further manufacture at the

same establishment. 

Quantities produced and consumed. Quantities of

each type of product produced by a company for

internal consumption within that same company.
Current Industrial Reports A-3

Quantity and value of new orders. The sales value

of orders received during the current reporting period

for products and services to be delivered immediately

or at some future date. Also represents the net sales

value of contract change documents that increase or

decrease the sales value of the orders to which they are 

related, when the parties concerned are in substantial

agreement as to the amount involved. Included as

orders are only those that are supported by binding

legal documents such as signed contracts or letter

contracts.

Quantity and value of shipments. The figures on

quantity and value of shipments represent physical

shipments of all products sold, transferred to other

establishments of the same company, or shipped on

consignment, whether for domestic or export sale. The

value represents the net sales price, f.o.b. plant, to the

customer or branch to which the products are shipped,

net of discounts, allowances, freight charges, and

returns. Shipments to a company's own branches are

assigned the same value as comparable appropriate

allocation of company overhead and profit. Products

bought and resold without further manufacture are

excluded.

Stocks. Total quantity of ending finished inventory.

Unfilled orders (backlog). Calculated by adding net

new orders and subtracting net sales from the backlog

at the end of the preceding year.

HISTORICAL NOTE

Data on selected electronic and associated

products have been collected by the Census Bureau

since 1961 on survey MA36N, Selected Electronics and

Associated Products. In 1985, survey MA36N was

divided into three annual surveys which are presently

collected as: MA334P, Communication Equipment,

Including Telephone, Telegraph, and Other Electronic

Systems and Equipment; MA334Q, Semiconductors,

Printed Circuit Boards, and Other Electronic

Components; and MA334S, Electromedical Equipment

and Irradiation Equipment (Including X-Ray). Historical

data may be obtained from Current Industrial Reports

available at your local Federal Depository Library.
