Many persons participated in the various activities of the 1992 Census of Construction

Industries. The overall planning and review of the census operations were performed by the

Economic Census Staff of the Economic Planning and Coordination Division.

This report was prepared in the Manufacturing and Construction Division. Barry A. Rappaport,

Assistant Chief for Construction and Mineral Census and Related Programs, was responsible for

the overall planning, management, and coordination of the census of construction industries.

Planning and implementation were under the direction of Patricia L. Horning, Chief, Construction

and Mineral Census Branch, with staff assistance by Juliana Van Berkum, Susan L. Hostetter,

Doris M. Kling, Carolyn J. Stone, and Linda M. Taylor. The sampling plans and variance and

estimation specifications were developed by Dennis K. Duke. Under the direction of C. Lloyd

Anderson, the Systems Support Staff maintained the small computers and assisted in the

management of computer output.

Systems and procedures for mailout, receipt, correspondence, data input, industry classification, other clerical processing, administrative-record processing, quality control, and the associated electronic computer programs, were developed in the Economic Planning and Coordination

Division.

Mailout preparation and receipt operations, clerical and analytical review activities, data

keying, and geocoding review were performed by the staff of the Data Preparation Division,

Judith N. Petty, Chief.

Geographic coding procedures and associated computer programs were developed by the staff

of the Geography Division, Joel Morrison, Chief.

The computer processing systems were developed and coordinated in the Economic

Statistical Methods and Programming Division, Charles P. Paulter, Jr., Chief, and Sarah W.

Baumgardner, Assistant Chief. Samuel Rozenel, Chief, Current Construction Branch, was

responsible for the design and implementation of the computer systems. The computer programs

were prepared under the supervision of Leonard S. Sammarco and Kevin J. Montgomery.

Computer processing was performed in the Computer Services Division, Marvin D. Raines,

Chief.

Introduction to

the Economic Census

PURPOSES AND USES OF THE ECONOMIC

CENSUS

The economic census is the major source of facts about

the structure and functioning of the Nation’s economy. It

provides essential information for government, business,

industry, and the general public.

The economic census furnishes an important part of the

framework for such composite measures as the gross

domestic product, input/ output measures, production and

price indexes, and other statistical series that measure

short-term changes in economic conditions.

Policymaking agencies of the Federal Government use

the data, especially in monitoring economic activity and

providing assistance to business.

State and local governments use the data to assess

business activities and tax bases within their jurisdictions

and to develop programs to attract business.

Trade associations study trends in their own and competing industries and keep their members informed of

market changes.

Individual businesses use the data to locate potential

markets and to analyze their own production and sales

performance relative to industry or area averages.

AUTHORITY AND SCOPE

Title 13 of the United States Code (sections 131, 191,

and 224) directs the Census Bureau to take the economic

census every 5 years, covering years ending in 2 and 7.

The 1992 Economic Census consists of the following eight

censuses:

• Census of Retail Trade

• Census of Wholesale Trade

• Census of Service Industries

• Census of Financial, Insurance, and Real Estate

Industries

• Census of Transportation, Communications, and

Utilities

• Census of Manufactures

• Census of Mineral Industries

• Census of Construction Industries

Special programs also cover enterprise statistics and

minority-owned and women-owned businesses. (The 1992

Census of Agriculture and 1992 Census of Governments

are conducted separately.) The next economic census is

scheduled to be taken in 1998 covering the year 1997.

AVAILABILITY OF THE DATA

The results of the economic census are available in

printed reports for sale by the U.S. Government Printing

Office and on compact discs for sale by the Census

Bureau. Order forms for all types of products are available

on request from Customer Services, Bureau of the Census,

Washington, DC 20233-8300. A more complete description of publications being issued from this census is on the

inside back cover of this document.

Census facts are also widely disseminated by trade

associations, business journals, and newspapers. Volumes containing census statistics are available in most

major public and college libraries. Finally, State data

centers in every State as well as business and industry

data centers in many States also supply economic census

statistics.

WHAT’S NEW IN 1992

The 1992 Economic Census covers more of the economy

than any previous census. New for 1992 are data on

communications, utilities, finance, insurance, and real estate,

as well as coverage of more transportation industries. The

economic, agriculture, and governments censuses now

collectively cover nearly 98 percent of all economic activity.

Among other changes, new 1992 definitions affect the

boundaries of about a third of all metropolitan areas. Also,

the Survey of Women-Owned Businesses has now been

expanded to include all corporations.

HISTORICAL INFORMATION

The economic census has been taken as an integrated

program at 5-year intervals since 1967 and before that for

1963, 1958, and 1954. Prior to that time, the individual

subcomponents of the economic census were taken separately at varying intervals.

 JOBNAME: No Job Name PAGE: 2 SESS: 48 OUTPUT: Wed Feb 15 09:25:07 1995 / pssw01/ disk2/ economic/ cc92i/ 00/ history

The economic census traces its beginnings to the 1810

Decennial Census, when questions on manufacturing were

included with those for population. Coverage of economic

activities was expanded for 1840 and subsequent censuses to include mining and some commercial activities. In

1902, Congress established a permanent Census Bureau

and directed that a census of manufactures be taken every

5 years. The 1905 Manufactures Census was the first time

a census was taken apart from the regular every-10-year

population census.

The first census of business was taken in 1930, covering 1929. Initially it covered retail and wholesale trade and

construction industries, but it was broadened in 1933 to

include some of the service trades.

The 1954 Economic Census was the first census to be

fully integrated—providing comparable census data across

economic sectors, using consistent time periods, concepts, definitions, classifications, and reporting units. It

was the first census to be taken by mail, using lists of firms

provided by the administrative records of other Federal

agencies. Since 1963, administrative records also have

been used to provide basic statistics for very small firms,

reducing or eliminating the need to send them census

questionnaires. The Enterprise Statistics Program, which

publishes combined data from the economic census, was

made possible with the implementation of the integrated

census program in 1954.

The range of industries covered in the economic censuses has continued to expand. The census of construction industries began on a regular basis in 1967, and the

scope of service industries was broadened in 1967, 1977,

and 1987. The census of transportation began in 1963 as

a set of surveys covering travel, transportation of commodities, and trucks, but expanded in 1987 to cover business

establishments in several transportation industries. For

1992, these statistics are incorporated into a broadened

census of transportation, communications, and utilities.

Also new for 1992 is the census of financial, insurance,

and real estate industries. This is part of a gradual expansion in coverage of industries previously subjected to

government regulation.

The Survey of Minority-Owned Business Enterprises

was first conducted as a special project in 1969 and was

incorporated into the economic census in 1972 along with

the Survey of Women-Owned Businesses.

An economic census has also been taken in Puerto

Rico since 1909, in the Virgin Islands of the United States

and Guam since 1958, and in the Commonwealth of the

Northern Mariana Islands since 1982.

Statistical reports from the 1987 and earlier censuses

provide historical figures for the study of long-term time

series and are available in some large libraries. All of the

census data published since 1967 are still available for

sale on microfiche from the Census Bureau.

AVAILABILITY OF MORE FREQUENT

ECONOMIC DATA

While the census provides complete enumerations every

5 years, there are many needs for more frequent data as

well. The Census Bureau conducts a number of monthly,

quarterly, and annual surveys, with the results appearing in

publication series such as Current Business Reports (retail

and wholesale trade and service industries), the Annual

Survey of Manufactures, Current Industrial Reports, and

the Quarterly Financial Report. Most of these surveys,

while providing more frequent observations, yield less

kind-of-business and geographic detail than the census.

The County Business Patterns program offers annual

statistics on the number of establishments, employment,

and payroll classified by industry within each county.

SOURCES FOR MORE INFORMATION

More information about the scope, coverage, classification system, data items, and publications for each of the

economic censuses and related surveys is published in the

Guide to the 1992 Economic Census and Related Statistics. More information on the methodology, procedures,

and history of the census will be published in the History of

the 1992 Economic Census. Contact Customer Services

for information on availability.

Census of Construction

GENERAL

The 1992 Census of Construction Industries covers all

employer establishments (establishments with payroll) primarily engaged in contract construction or construction on

their own account for sale as defined in the Standard

Industrial Classification Manual: 19871 (SIC). This industrial classification system has been developed by experts

on classification in government and private industry under

the guidance of the Office of Management and Budget and

is in general use among government agencies and among

organizations outside the government.

Contract construction. The SIC manual defines construction in three broad types of activity:

1. Building construction by general contractors or by

operative builders. General building contractors are

primarily engaged in the construction of dwellings,

office buildings, stores, farm buildings, and other building projects. Operative builders who build on their own

account for sale are also included here. However,

investment builders who build structures on their own

account for rent are classified in Real Estate.

2. Heavy construction general contractors. Heavy construction general contractors are primarily engaged in

the construction of highways, bridges, pipelines, sewers and water lines, marine construction, power, and

petro-chemical plants and other nonbuilding construction projects. Special trade contractors are classified

in heavy construction, if they are specifically engaged

in the following activities: grading for highway and

airport runways; guardrail construction; installation of

highway signs; asphalt and concrete construction of

roads, highways, streets, and public sidewalks; trenching, cable laying; conduit construction; underwater

rock removal; pipeline wrapping; or land clearing and

leveling.

3. Constructionby other specialtrade contractors. These

contractors include plumbers, painters, carpenters,

electricians, brick layers, roofers, etc. For the most

part, they perform their work at the site of construction,

although they may also have shops where they perform work incidental to the job site.

General contractors in both the building and the heavy

construction field usually assume responsibility for an

entire construction project, but may subcontract to others

all of the actual construction work or those portions of the

project requiring special skills or equipment. Special trade

contractors may work for general contractors, for other

subcontractors, or may work directly for the owner of the

property.

Each establishment receiving a questionnaire was requested

to report the percent of total dollar value of business done

for each kind-of-business activity engaged in during 1992.

This information was used for the computer assignment of

appropriate industry classifications. During this work, various tests were also made using other data reported on the

questionnaire. The proportion of construction work to total

business was checked to verify that the establishment was

primarily in construction. Also taken into consideration

were the types of structures worked on during the year and

the extent of work undertaken for other contractors.

Construction establishments often engage in various

construction activities. It is necessary, however, to assign

a single industry code to the establishment based on its

major activity. Therefore, the statistics shown for an industry reflect not only the primary activity of the establishments in the industry but also their secondary activities.

The industry reports, however, do present data on the

extent of secondary activities.

Prior to 1992, this census also included one industry

classified in the Real Estate area, SIC 6552, Land Subdividers and Developers, Except Cemeteries. This industry

is covered in the 1992 Census of Financial, Insurance,

and Real Estate Industries.

ESTABLISHMENT BASIS OF REPORTING

The census of construction industries is conducted on

an establishment basis. A ‘‘construction establishment’’ is

defined as a relatively permanent office or other place of

business where the usual business activities related to

construction are conducted. With some exceptions, a

relatively permanent office is one which has been established for the management of more than one project or job

and which is expected to be maintained on a continuing

basis. Such ‘‘establishment’’ activities include, but are not

limited to estimating, bidding, purchasing, supervising, and

operation of the actual construction work being conducted

at one or more construction sites. Separate construction

reports were not required for each project or construction

site.

Companies with more than one construction establishment were required to submit a separate report for each

establishment operated during all or any part of 1992. The

census of construction industries figures represent a summary of records for individual establishments rather than

for companies.

If an establishment was engaged in construction and

one or more distinctly different lines of economic activity

(wholesale or retail trade, service, manufacturing, mining,

etc.) at the same place of business, it was requested to file

a separate report for each activity, provided that the

activity was of substantial size and separate records were

maintained or substantially accurate estimates could be

prepared.

If a separate establishment report could not be prepared for each activity, then a construction report was

requested covering all activities of that establishment

providing that the 1992 value of construction work exceeded

the gross receipts from each of its other activities.

Construction businesses with no payroll during 1992

(nonemployers) were not required to file census reports.

Tabulation of data for these businesses are based on

administrative records and are shown only in U.S. summary publications and the geographic area reports series.

Refer to the section on ‘‘Sample Design’’ for details.

Foreign construction activities were not included in this

census.

SAMPLE DESIGN, ESTIMATION PROCEDURES,

AND RELIABILITY OF ESTIMATES

The companies included in the 1992 Census of Construction Industries were identified as part of an operation

common to all 1992 Economic Censuses. Construction

companies were divided into employers (companies with

payroll) and nonemployers (companies without payroll).

Statistical information for the employers was obtained in

the census by a survey which included all medium size and

large employers and a sample of the smaller ones. Census

reports were not required from the nonemployers. Statistics on nonemployers were obtained from administrative

records of other agencies of the Federal Government.

Employer Companies

Developing the sampling frame for employer companies. This operation started with obtaining a list of all

construction companies in the active records of the Internal Revenue Service (IRS) which were subject to payment

of Federal Insurance Contributions Act (FICA) taxes. The

basic source for this list has been the Internal Revenue

Service Business Master File, a comprehensive list of

companies engaged in business activities in the United

States. The file contains the name, address, and form of

ownership of each company and also indicates whether or

not the company is subject to the FICA. Each company in

this file is assigned a unique employer identification (EI)

number which it uses in filing its various reports with the

IRS. The Social Security Administration (SSA) maintains a

similar list using the same identification numbers, which

also contains information on the industrial classification of

each company. The Bureau of the Census obtained both of

these lists and combined them.

Under special arrangements which safeguarded the

confidentiality of the information, the Bureau also obtained

administrative-record data on payrolls and receipts and

added these data to the combined list. The list, thus

created from the IRS-SSA information, was a list of employer

companies. However, for the 1992 Economic Census the

basic reporting unit is the ‘‘establishment.’’ Therefore,

steps were taken to identify the individual establishments

of those companies which operate more than one place of

business. The information for making this determination

was obtained by means of the Company Organization

Survey (COS), an annual canvass of all known multiestablishment companies and large single-establishment companies. Thus, the 1992 Economic Census list for singleestablishment employer companies was obtained from the

IRS-SSA, but the list of establishments of multiestablishment employer companies was obtained directly from

those companies in the COS. Refer to the section on

‘‘Establishment Basis for Reporting’’ for details.

In general, the IRS-SSA list provided sufficient industrial

classification data to assign a company to the proper

economic census, but there were a number of companies

for which this information was inadequate or unavailable. A

special form, NC-9923, General Schedule, was mailed to

all such companies, requesting information on the nature

of the company’s activities. From the information reported,

the company was given an industrial classification code

and assigned to the appropriate economic census. Since

construction companies found in this way were identified

only after the regular census mailing had taken place, they

were treated as a supplement to the basic list.

Selecting the employer sample. The sample was designed

to provide reliable State and metropolitan area estimates

for each construction industry. It consisted of all construction establishments in multiestablishment companies, all

single-establishment companies with 1991 administrative

payroll of $480,000 or more and a probability sample of

single-establishment companies with payroll under that

amount. Supplementing the sample were construction

companies identified from the NC-9923, General Schedule. Also affecting the sample were the misclassified

companies; i.e., companies included in the samples of

other trade areas which reported they were construction

companies and companies originally classified in construction which reported they were not construction companies.

Of the 547,000 single-establishment employer companies initially classified as construction companies, 158,000

were included in the sample. All of the 11,000 establishments of multiestablishment companies were included in

VI CENSUS OF CONSTRUCTION CONSTRUCTION—INDUSTRY SERIES
 JOBNAME: No Job Name PAGE: 3 SESS: 56 OUTPUT: Tue Apr 4 09:52:56 1995 / pssw01/ disk2/ economic/ cc92i/ 00/ 07intro

the sample. There was a net increase in the sample of

48,000 establishments resulting from establishments originally unclassified (receiving the NC-9923) or misclassified.

The probability sample of the smaller single-establishment

companies was a stratified random sample. Strata were

formed from all establishments with the same initial fourdigit SIC code, in the same State, in the same metropolitan

area, or in the balance of the State, and in the same size

class based on estimated total employment. If the fourdigit SIC code for an establishment was incomplete, the

establishment was placed in a stratum for miscellaneous

companies. Because they were small, all companies were

included in the sample for the following three industries:

SIC 1622, Bridge, Tunnel, and Elevated Highway Construction Contractors; SIC 1795, Wrecking and Demolition Work

Special Trade Contractors; and SIC 1796, Installation or

Erection of Building Equipment Special Trade Contractors.

Estimation procedures for 1992 and 1987 data. Since

all larger employer companies and some smaller ones

were included in the census, sample estimation was

required only for the universe of companies not selected

with certainty. The published statistics are the totals of the

estimates for the sampled companies and the aggregates

for the certainty companies. All estimates for 1992 and

1987 published here are simple unbiased estimates of the

form:

n

c

x’

c = Σ xi

/ pi

i =1

where: x’

c is the simple unbiased estimate of a characteristic for a publication cell.

x

i is the reported value of a characteristic for

an individual establishment in the publication cell.

p

i is the selection probability of that firm.

n

c is the number of firms in the sample for the

cell.

Data for certain characteristics were reported as a

percentage of the dollar value of business done. Before

this formula was applied to those characteristics, it was

necessary to convert the reported percentages into dollars.

Reliability of employer statistics. Since the estimates

for employer establishments in these reports are based on

the samples, they are subject to sampling variability and

may be expected to differ from results which would have

been obtained if a complete census had been taken using

the same forms and procedures. The sampling errors

shown in the tables were estimated directly from the

sample reports, using methods appropriate for the sample

design and form of estimation used. The relative standard

error is a measure of sampling variability; i.e., the variation

that might occur by chance because only a sample of the

population is surveyed. As calculated for this report, the

relative standard error also partially reflects the effect of

random errors of response and processing, but it does not

take into account the effect of any consistent biases due to

those types of errors. The chances are about 68 out of 100

that an estimate from the sample would differ from a

complete census by less than the relative standard error.

The chances are about 95 out of 100 that the difference is

less than twice the relative standard error and about 99 out

of 100 that it is less than 2-1/ 2 times the relative standard

error. Individual estimates with large relative standard

errors have been shown in the published tables. Any such

estimates should be used with caution. The very large

relative standard errors generally occur for the smaller

estimates.

Relative standard errors have been calculated for all of

the published statistics, although they are shown for each

statistic only in the tables presenting detailed statistics.

Other tables show relative standard errors only for certain

characteristics because of lack of space.

As calculated for this report, the relative standard error

measures certain nonsampling errors, but does not measure any systematic biases in the data. Bias is the difference, averaged over all possible samples with the same

size and design, between the estimates and the true value

being estimated. Nonsampling errors can be attributed to

many sources: inability to obtain information about all

cases in the sample; definitional difficulties; differences in

interpretation of questions; inability or unwillingness of

respondents to provide correct information; and errors

made in processing the data. Although no direct measurements of the biases have been obtained, it is believed that

most of the important response and operational errors

were detected in the course of reviewing the data for

reasonableness and consistency.

A potential source of bias is in the imputation for those

establishments that have not responded by the time of

final publication. Data were estimated for establishments

that did not report by that date, although selected establishments were contacted again to obtain as much information on the telephone as possible. Some publication

cells in which more than 40 percent of the data were not

reported have been suppressed.

Nonemployer Companies

As described earlier, the information derived from the

business income tax returns of all companies was matched

to the census employer file on the basis of common

identification numbers. Those business income tax returns

which could not be matched were further classified on the

basis of several characteristics. Returns with characteristics consistent with companies without payroll were treated

as nonemployers. The nonemployer construction companies were not required to file census reports.

For ‘‘number of establishments,’’ each separate income

tax return was assumed to be an establishment. ‘‘All

business receipts’’ was based on receipts information

reported on the tax return.

Since no sampling was involved in the nonemployer

establishments, the statistics for nonemployers are not

subject to sampling variability. However, these data are

subject to an unknown amount of reporting and processing

errors which could not be detected by the Census Bureau.

CENSUS REPORT FORMS

Information for the 1992 Census of Construction Industries was obtained from employer establishments primarily

through the use of 22 questionnaires, determined by

industry classification and size. Standard forms and short

forms were developed for each of the following SIC

groups: 15, 16, 171, 172, 173, 174, 175, 176, 177, 178, and

179. Establishments with 1991 administrative payroll of

$1,080,000 or more all received the standard form. For

those sample establishments with payroll under that amount,

half received the standard form and half received the short

form. The short forms covered only major items and

omitted some of the detail found in the longer forms.

In reviewing and developing the questionnaires,

comments and recommendations were elicited from

construction trade associations and advisory groups.

Also, approximately 6,000 establishments in SIC’s 1521,

1629, and 1799 were surveyed in the Census of Construction Industries 1989 Pretest. This survey consisted of four

panels which received one of four experimental questionnaries and one panel which received the control questionnaire. Along with the questionnaire, these establishments

received an evaluation questionnaire, which requested

information about respondents’ reactions to the questionnaire, problems in completing the questionnaire, and how

long it took to complete the questionnaire. Results from

the 1989 Pretest questionnaire are reflected as reworded

questions, improved instructions, and restructured value of

business questions in the 1992 questionnaires.

DATA PROCESSING

The 1992 census report forms were mailed out in

December 1992. They were mailed from and returned to

the Census Bureau’s Data Preparation Division in Jeffersonville, IN, where routine editing and coding of the report

forms were also accomplished. Collection of these report

forms was essentially completed in July 1993.

The returned reports underwent extensive processing.

A preliminary edit done at the time of data entry identified

obviously deficient reports and reports needing clarification. When necessary, these problems were resolved by

further contact with the respondents. Next, the data were

transmitted to Census Bureau headquarters near Washington, DC.

Data records, then, underwent a detailed computer

review and analysis. The records containing significant

problems were referred for further analytical review and, if

necessary, contacts were made with the respondents. The

computer performed most classification coding (such as

industry coding, geographic coding, and size coding), and

imputation for missing items or for reports not received in

time for tabulation. The imputation was performed on an

industry (or industry group) and State (or geographic

group) basis using all available response and administrative data.

The data records were then tabulated on an industry

basis. Industry totals were subjected to analytical review,

and selected statistics were prepared for the preliminary

reports. Corrections resulting from this review were made

to the computer records and final tabulations were produced.

The review of a preliminary report for an industry often

uncovered the need for corrections or revisions to the data

for another industry for which a preliminary report had

already been published. The final reports incorporate all

revisions and corrections made during the review of the

preliminary reports and contain considerable more data

than were published in those reports.

GEOGRAPHIC CLASSIFICATION

Information for the 1992 Census of Construction Industries’

final industry report series is classified on the basis of two

types of geographic distributions: (1) physical location of

the establishment, and (2) location of construction work. A

separate code was assigned on each basis allowing us to

present data by both physical location of the establishment

and location of construction work.

The geographic area reports series presents similar

data by industry for each State (physical location of the

establishment) and for selected MSA’s, CMSA’s and PMSA’s.

CHANGE IN COLLECTION METHODOLOGY FOR

VALUE OF CONSTRUCTION WORK DONE

In 1987 and 1992, the ‘‘value of construction work’’ was

collected to better measure actual construction activity

done during the year. In 1992, this item was collected as a

total of three separate items. These items ( receipts from

construction contract work, value of speculative construction work, and value of construction work done for own

use) were collected separately to emphasize construction

activity that had been poorly reported in previous censuses.

Receipts from the sale of land were not collected

separately in 1992, as in 1987, but are still excluded from

the value of construction work done.

All dollar values are shown in current dollars for the

years specified and have not been adjusted for inflation.

DUPLICATION IN VALUE OF CONSTRUCTION

WORK

The aggregate of value of construction work reported by

all construction establishments in each of the several

industry, geographic area, or other groupings in this census contains varying amounts of duplication, since the

other construction firms and may also be included in the

subcontractors’ value of construction work. To avoid this

duplication, a ‘‘net’’ value of construction work figure has

been derived for each establishment by subtracting the

costs for construction work subcontracted to others from

the value of construction work.

Duplication in value of business between other construction and nonconstruction industries results from the use of

products of these other industries as input materials by

construction establishments. ‘‘Value added’’ avoids this

duplication and is, for most purposes, the best measure for

comparing the relative economic importance of industries

or areas. ‘‘Value added’’ is defined in the 1992 Census of

Construction Industries as equal to dollar value of business

done less costs for construction work subcontracted to

others and payments for materials, components, supplies,

and fuels.

SPECIAL TABULATIONS

Special tabulations of data collected in the 1992 Census

of Construction Industries may be obtained on computer

tape or in tabular form. The data will be in summary form

and subject to the same rules prohibiting disclosure of

confidential information (including name, address, kind of

business, or other data for individual business establishments or companies) as are the regular publications.

Special tabulations are prepared on a cost basis. A

request for a cost estimate, as well as exact and detailed

specifications of the type and format of the data to be

provided, should be directed to the Chief, Manufacturing

and Construction Division, Bureau of the Census, Washington, DC 20233.

To discuss a special tabulation before submitting specifications, call 301-457-4680.

COMPARABILITY OF CENSUS OF

CONSTRUCTION INDUSTRIES DATA WITH

OTHER DATA

Data contained in the reports of the 1992 Census of

Construction Industries are not the same as the data

published in the Census Bureau’s monthly Construction

Reports, Series C30, Value of New Construction Put in

Place. The main difference is that the C30 series covers all

new construction put in place without regard to who is

performing the construction activity; whereas, the construction census figures cover both new construction and

maintenance and repair work done by establishments

classified in the construction industry. Significant amounts

of construction are done by establishments classified

outside of construction (in real estate, manufacturing,

utilities, and communications, for example), both as ‘‘force

account’’ construction and construction done for others. In

addition, the value in place series includes constructionrelated expenses such as architectural and engineering

costs and the costs of materials supplied by owners which

are normally not reflected in the census of construction

industries.

Data contained in the reports of the census of construction industries may also differ from industry data in ‘‘Employment and Earnings Statistics,’’ published by the Bureau of

Labor Statistics and ‘‘Statistics of Income,’’ published by

the Internal Revenue Service. These differences arise

from varying definitions of scope, coverage, timing, classification, and methodology.

ABBREVIATIONS AND SYMBOLS

The following abbreviations and symbols are used in

this publication:

* Sampling error exceeds 40 percent.

** Represents the sum of all employees during

pay periods including 12th of March, May,

August, and November, divided by 4.

- Represents zero.

† Represents value of construction work less

costs for construction work subcontracted to

others. (See Duplication in Value of Construction Work.)

†† Represents dollar value of business done less

costs for construction work subcontracted to

others and costs for materials, components,

supplies, and fuels. In 1987, for SIC 1531, land

receipts were collected as a component of

dollar value of business and, therefore, were

subtracted from this value. (See Duplication in

Value of Construction Work.)

(D) Withheld to avoid disclosing data for individual

companies; data are included in higher level

totals.

(NA) Not available.

(S) Withheld because estimate did not meet publication standards on the basis of either the

response rate, associated relative standard

error, or a consistency review.

(X) Not applicable.

(Z) Less than half of the unit shown.

Summary of Findings

Establishments classified in this industry are primarily

engaged in electrical power and lighting installation at the

construction site. This industry also includes establishments engaged in the installation of telecommunication

equipment, electronic controls, security systems, and highway signals. For additional examples, refer to the Standard

Industrial Classification Manual: 19871 (SIC) published by

the Office of Management and Budget, Executive Office of

the President.

During 1992, the establishments with paid employees

classified in this industry accounted for $40.7 billion in total

dollar value of business. Of this amount, $40.3 billion were

for the value of construction work. These establishments

paid out $14.9 billion for materials, components, and

supplies and $1.7 billion for construction work subcontracted to others. Costs for selected power, fuels, and

lubricants for the industry were $568 million. Value added

for 1992 was $23.5 billion.

There were 54,022 establishments with total employment averaging 487,072 during the year. Total payroll for

1992 was $13.6 billion.

Larger establishments with 20 employees or more,

while representing only 9 percent of the total number of

employer establishments in this industry, accounted for 62

percent of all business done.

A ‘‘construction establishment’’ is defined as a relatively

permanent office, or other place of business, where the

usual business activities related to construction are conducted. A separate census report was required from each

sampled establishment covering domestic operations. Separate reports were not, however, required for each project or

construction site.

For 1987 and earlier censuses, receipts from the sale of

land were collected separately for general contractors and

operative builders. These receipts were included in the

total dollar value of business done but excluded from the

value of construction work done. For 1992, receipts from

the sale of land were not collected separately but are still

excluded from the value of construction work done. All

dollar values are shown in current dollars for the years

specified and have not been adjusted for inflation.

The data in this report are estimated from a sample

survey and are subject to sampling variability as well as

errors of response and nonreporting. The relative standard

error shown in the tables is a measure of sampling

variability. Descriptions of the sampling, estimating procedures, and data reliability are included in the introduction.

assets, intangible assets, and nondepreciable assets.

Data on assets and depreciation were collected separately for: (1) buildings and other structures, additions, and

related facilities; and (2) machinery and equipment.

Respondents were also asked to report capitalized

expenditures, depreciation charges, and the gross value

of assets sold, retired, scrapped, and destroyed during

1992.

Capital expenditures. Refers to all costs actually incurred

during 1992 which were or would be chargeable to the

fixed assets accounts of the reporting establishments and

ordinarily maintained. These expenditures cover the acquisition, the construction, and the major alteration of the

reporting establishment’s own buildings and other structures, whether purchased, constructed under contract, or

constructed by the reporting establishment’s own forces;

and the acquisition of machinery and equipment.

If leasing arrangements met the criteria set down by the

Financial Accounting Standards Board (FASB) for a capital

lease, respondents were instructed to report the original

cost or market value of that equipment or building as a

If capital expenditures were not recorded directly at the

establishment level but handled centrally at the company

or division level, respondents were requested to report

appropriate estimates for the individual establishments.

Inventories. Includes all of the materials and supplies

that are owned regardless of where they are held. Excludes

materials which are owned by others, but held by the

responsible for the inventories even if these inventories

were held at a separate location.

Ownership of construction projects. Shows the distribution of the value of construction work done by ownership

of the project; that is, Government owned or privately

owned. This classification relates to the ownership of the

projects or work undertaken during the construction phase.

Government owned projects are shown separately for

Federal and State and local governments.

Value of construction work subcontracted in from

others. Includes the value of construction work during

1992 for work done by reporting establishments as subcontractors. Establishments were asked to report the

approximate percent of total value of construction work

accounted for by such work, and the percentages reported

were applied to the reported value of construction work to

develop a value for this item.

Types of construction. Provides data by the types of

buildings, structures, or other facilities being constructed

or worked on by construction establishments in 1992.

Respondents were instructed that each building, structure,

or other facility should be classified in terms of its function.

the restaurant category whether it was designed as a

commercial restaurant building or an auxiliary unit of an

educational institution. If respondents worked on more

than one type of building or structure in a multibuilding

complex, they were instructed to report separately for each

building or type of structure. If they worked on a building

that had more than one purpose; i.e, office and residential,

or commercial, they were to classify the building by major

purpose.

In addition, all respondents were requested to report the

percentage of the value of construction work done for new

construction, additions, alterations, or reconstruction, and
