Introduction to the Economic Census

PURPOSES AND USES OF THE ECONOMIC CENSUS

The economic census is the major source of facts aboutthe structure and functioning of the Nation’s economy. Itprovides essential information for government, business,industry, and the general public. Title 13 of the UnitedStates Code (Sections 131, 191, and 224) directs the Cen-sus Bureau to take the economic census every 5 years,covering years ending in 2 and 7.

The economic census furnishes an important part of theframework for such composite measures as the grossdomestic product estimates, input/output measures, pro-duction and price indexes, and other statistical series thatmeasure short-term changes in economic conditions. Spe-cific uses of economic census data include the following:

• Policymaking agencies of the Federal Government usethe data to monitor economic activity and assess theeffectiveness of policies.

• State and local governments use the data to assessbusiness activities and tax bases within their jurisdic-tions and to develop programs to attract business.

• Trade associations study trends in their own and com-peting industries, which allows them to keep their mem-bers informed of market changes.

• Individual businesses use the data to locate potentialmarkets and to analyze their own production and salesperformance relative to industry or area averages.

ALL-NEW INDUSTRY CLASSIFICATIONS

Data from the 1997 Economic Census are published pri-marily on the basis of the North American Industry Classi-fication System (NAICS), unlike earlier censuses, whichwere published according to the Standard Industrial Classi-fication (SIC) system. NAICS is in the process of beingadopted in the United States, Canada, and Mexico. Mosteconomic census reports cover one of the following NAICSsectors:

21 Mining22 Utilities23 Construction31-33 Manufacturing42 Wholesale Trade44-45 Retail Trade48-49 Transportation and Warehousing51 Information

52 Finance and Insurance53 Real Estate and Rental and Leasing54 Professional, Scientific, and Technical

Services55 Management of Companies and Enterprises56 Administrative and Support and Waste

Management and Remediation Services61 Educational Services62 Health Care and Social Assistance71 Arts, Entertainment, and Recreation72 Accommodation and Foodservices81 Other Services (except Public Administration)

(Not listed above are the Agriculture, Forestry, Fishing, andHunting sector (NAICS 11), partially covered by the censusof agriculture conducted by the U.S. Department of Agri-culture, and the Public Administration sector (NAICS 92),covered by the census of governments conducted by theCensus Bureau.)

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).

RELATIONSHIP TO SIC

While many of the individual NAICS industries corre-spond directly to industries as defined under the SIC sys-tem, most of the higher level groupings do not. Particularcare should be taken in comparing data for retail trade,wholesale trade, and manufacturing, which are sectortitles used in both NAICS and SIC, but cover somewhat dif-ferent groups of industries. The industry definitions dis-cuss the relationships between NAICS and SIC industries.Where changes are significant, it will not be possible toconstruct time series that include data for points bothbefore and after 1997.

For 1997, data for auxiliary establishments (those func-tioning primarily to manage, service, or support the activi-ties of their company’s operating establishments, such asa central administrative office or warehouse) will not beincluded in the sector-specific reports. These data will bepublished separately.

GEOGRAPHIC AREA CODING

Accurate and complete information on the physicallocation of each establishment is required to tabulate thecensus data for the states, metropolitan areas (MAs), coun-ties, parishes, and corporate municipalities including cit-ies, towns, villages, and boroughs. Respondents were

INTRODUCTION 11997 ECONOMIC CENSUS

U.S. Census Bureau, 1997 Economic Census

required to report their physical location (street address,municipality, county, and state) if it differed from theirmailing address. For establishments not surveyed by mail(and those single-establishment companies that did notprovide acceptable information on physical location), loca-tion information from Internal Revenue Service tax formsis used as a basis for coding.

BASIS OF REPORTING

The economic census is conducted on an establishmentbasis. A company operating at more than one location isrequired to file a separate report for each store, factory,shop, or other location. Each establishment is assigned aseparate industry classification based on its primary activ-ity and not that of its parent company.

DOLLAR VALUES

All dollar values presented are expressed in current dol-lars; i.e., 1997 data are expressed in 1997 dollars, and1992 data, in 1992 dollars. Consequently, when makingcomparisons with prior years, users of the data shouldconsider the changes in prices that have occurred.

All dollar values are shown in thousands of dollars.

AVAILABILITY OF ADDITIONAL DATA

Reports in Print and Electronic Media

All results of the 1997 Economic Census are availableon the Census Bureau Internet site (www.census.gov) andon compact discs (CD-ROM) for sale by the Census Bureau.Unlike previous censuses, only selected highlights arepublished in printed reports.

HISTORICAL INFORMATION

The economic census has been taken as an integratedprogram at 5-year intervals since 1967 and before that for1954, 1958, and 1963. Prior to that time, individual com-ponents of the economic census were taken separately atvarying intervals.

The economic census traces its beginnings to the 1810Decennial Census, when questions on manufacturing wereincluded with those for population. Coverage of economicactivities was expanded for the 1840 Decennial Censusand subsequent censuses to include mining and somecommercial activities. The 1905 Manufactures Census wasthe first time a census was taken apart from the regulardecennial population census. Censuses covering retail andwholesale trade and construction industries were added in1930, as were some covering service trades in 1933. Cen-suses of construction, manufacturing, and the other busi-ness service censuses were suspended during World WarII.

The 1954 Economic Census was the first census to befully integrated: providing comparable census data acrosseconomic sectors, using consistent time periods, con-cepts, definitions, classifications, and reporting units. Itwas the first census to be taken by mail, using lists offirms provided by the administrative records of other Fed-eral agencies. Since 1963, administrative records alsohave been used to provide basic statistics for very smallfirms, reducing or eliminating the need to send them cen-sus questionnaires.

The range of industries covered in the economic cen-suses expanded between 1967 and 1992. The census ofconstruction industries began on a regular basis in 1967,and the scope of service industries, introduced in 1933,was broadened in 1967, 1977, and 1987. While a fewtransportation industries were covered as early as 1963, itwas not until 1992 that the census broadened to includeall of transportation, communications, and utilities. Alsonew for 1992 was coverage of financial, insurance, andreal estate industries. With these additions, the economiccensus and the separate census of governments and cen-sus of agriculture collectively covered roughly 98 percentof all economic activity.

Printed statistical reports from the 1992 and earliercensuses provide historical figures for the study of long-term time series and are available in some large libraries.All of the census reports printed since 1967 are still avail-able for sale on microfiche from the Census Bureau.CD-ROMs issued from the 1987 and 1992 Economic Cen-suses contain databases including nearly all data pub-lished in print, plus additional statistics, such as ZIP Codestatistics, published only on CD-ROM.

Utilities

SCOPE

The Utilities sector (sector 22) comprises establish-ments engaged in the provision of the following utility ser-vices: electric power, natural gas, steam supply, water sup-ply, sewage removal. Within this sector, the specificactivities associated with the utility services provided varyby utility: electric power includes generation, transmis-sion, and distribution; natural gas includes distribution;steam supply includes provision and/or distribution; watersupply includes treatment and distribution; and sewageremoval includes collection, treatment, and disposal ofwaste through sewer systems and sewage treatment facili-ties.

Excluded from this sector are establishments primarilyengaged in waste management services classified in Sub-sector 562, Waste Management and Remediation Services.These establishments also collect, treat, and dispose ofwaste materials; however, they do not use sewer systemsor sewage treatment facilities.

GENERAL

A list of reports that provide statistics on sector 22 fol-lows.

Geographic area report. There is a separate report foreach state, the District of Columbia, and the United States.Each state report presents general statistics on number ofestablishments, revenue, payroll, and establishments withemployment by kind of business for the state and metro-politan areas (MAs). Greater kind-of-business detail isshown for larger areas. The United States report presentsdata for the United States as a whole.

Sources of revenue report. This report presentssources of revenue data for establishments by kind ofbusiness. Data are presented for the United States.

Establishment and firm size (including legal form oforganization) report. This report presents revenue,payroll, and employment data for the United States by rev-enue size, by employment size, and by legal form of orga-nization for establishments with paid employees; and byrevenue size (including concentration by largest firms), byemployment size, and by number of establishments oper-ated (single units and multiunits) for firms with paidemployees.

Miscellaneous subjects report. This report presentsdata for establishments with paid employees for a variety

of industry-specific questions. Presentation of data variesby kind of business.

GEOGRAPHIC AREAS COVERED

The level of geographic detail varies by report. Datamay be presented for:

1. The United States as a whole.

2. States and the District of Columbia.

3. Consolidated metropolitan statistical areas (CMSAs)and primary metropolitan statistical areas (PMSAs)defined by the Office of Management and Budget(OMB) as of June 30, 1997. A CMSA is an area used tofacilitate the presentation and analysis of data forlarge concentrations of metropolitan populations. Itincludes two or more contiguous PMSAs which have apopulation of at least 1,000,000 (according to the1990 Census of Population or subsequent special cen-sus) and which meet specific criteria of urban charac-ter and of social and economic integration.

4. Metropolitan statistical areas (MSAs) defined by theOMB as of June 30, 1997. An MSA is an integrated eco-nomic and social unit with a population nucleus of atleast 50,000 inhabitants (according to the 1990 Cen-sus of Population or subsequent special census). EachMSA consists of one or more counties meeting stan-dards of metropolitan character. In New England, citiesand towns rather than counties are the componentgeographic units.

COMPARABILITY OF THE 1992 AND 1997 CENSUSES

The 1997 Economic Census is the first census topresent data based on the new North American IndustryClassification System (NAICS). Previous census data werepresented according to the Standard Industrial Classifica-tion (SIC) system developed some 60 years ago. Due tothis change, comparability between census years may belimited. Comparative statistics will be included as part ofthe Core Business Statistics Reports.

DISCLOSURE

In accordance with Federal law governing censusreports (Title 13 of the United States Code), no data are

UTILITIES 51997 ECONOMIC CENSUS


published that would disclose the operations of anindividual establishment or business. However, the num-ber of establishments in a kind-of-business classification isnot considered a disclosure; therefore, this informationmay be released even though other information is with-held.

AVAILABILITY OF MORE FREQUENT ECONOMICDATA

The Census Bureau’s County Business Patterns programoffers annual statistics on the number of establishments,employment, and payroll classified by industry withineach county.

Appendix A.Explanation of Terms

ANNUAL PAYROLL

Payroll includes all forms of compensation such as sala-ries, wages, commissions, dismissal pay, bonuses, vaca-tion allowances, sick-leave pay, and employee contribu-tions to qualified pension plans paid during the year to allemployees. For corporations, payroll includes amountspaid to officers and executives; for unincorporated busi-nesses, it does not include profit or other compensation ofproprietors or partners. Payroll is reported before deduc-tions for social security, income tax insurance, union dues,etc. This definition of payroll is the same as that used bythe Internal Revenue Service (IRS) on form 941.

FIRST-QUARTER PAYROLL ($1,000)

Represents payroll paid to persons employed at anytime during the quarter January to March 1997.

NUMBER OF EMPLOYEES

Paid employees consist of the full-time and part-timeemployees, including salaried officers and executives ofcorporations. Included are employees on paid sick leave,paid holidays, and paid vacations; not included are propri-etors and partners of unincorporated businesses. The defi-nition of paid employees is the same as that is used on IRSform 941.

Includes all employees who were on the payroll duringthe pay period including March 12.

NUMBER OF ESTABLISHMENTS

An establishment is a single physical location at whichbusiness is conducted. It is not necessarily identical with acompany or enterprise, which may consist of one estab-lishment or more. Economic census figures represent asummary of reports for individual establishments ratherthan companies. For cases where a census report wasreceived, separate information was obtained for each loca-tion where business was conducted. When administrative

records of other Federal agencies were used instead of acensus report, no information was available on the num-ber of locations operated. Each economic census estab-lishment was tabulated according to the physical locationat which the business was conducted. The count of estab-lishments represents those in business at any time during1997.

When two or more activities were carried on at a singlelocation under a single ownership, all activities generallywere grouped together as a single establishment. Theentire establishment was classified on the basis of itsmajor activity and all data for it were included in that clas-sification. However, when distinct and separate economicactivities (for which different industry classification codeswere appropriate) were conducted at a single locationunder a single ownership, separate establishments reportsfor each of the different activities were obtained in thecensus.

REVENUE

Includes revenue from all business activities whether ornot payment was received in the census year. Revenuedoes not include sales and other taxes collected from cus-tomers and remitted directly by the firm to a local, state,or Federal tax agency.

SALES, RECEIPTS, OR REVENUE ESTIMATED(PERCENT)

Percent of total sales/receipts/revenue that wasimputed based on historic company ratios or administra-tive records, or on industry averages.

SALES, RECEIPTS, OR REVENUE FROM ADMINISTRA-TIVE RECORDS (PERCENT)

Percent of total sales/receipts/revenue obtained fromadministrative records of other Federal agencies.

APPENDIX A A–1UTILITIES


Appendix B.NAICS Codes, Titles, and Descriptions

22 UTILITIES

The Utilities sector comprises establishments engagedin the provision of the following utility services: electricpower, natural gas, steam supply, water supply, and sew-age removal. Within this sector, the specific activities asso-ciated with the utility services provided vary by utility:electric power includes generation, transmission, and dis-tribution; natural gas includes distribution; steam supplyincludes provision and/or distribution; water supplyincludes treatment and distribution; and sewage removalincludes collection, treatment, and disposal of wastethrough sewer systems and sewage treatment facilities.

Excluded from this sector are establishments primarilyengaged in waste management services classified in Sub-sector 562, Waste Management and Remediation Services,which also collect, treat, and dispose of waste materials;however, they do not use sewer systems or sewage treat-ment facilities.

221 Utilities

Industries in the Utilities subsector provide electricpower, natural gas, steam supply, water supply, and sew-age removal through a permanent infrastructure of lines,mains, and pipes. Establishments are grouped togetherbased on the utility service provided and the particularsystem or facilities required to perform the service.

2211 Electric Power Generation, Transmission andDistribution

This industry group comprises establishments primarilyengaged in generating, transmitting, and/or distributingelectric power. Establishments in this industry group mayperform one or more of the following activities: (1) oper-ate generation facilities that produce electric energy; (2)operate transmission systems that convey the electricityfrom the generation facility to the distribution system; and(3) operate distribution systems that convey electricpower received from the generation facility or the trans-mission system to the final consumer.

22111 Electric Power Generation

This industry comprises establishments primarilyengaged in operating electric power generation facilities.These facilities convert other forms of energy, such aswater power (i.e., hydroelectric), fossil fuels, nuclear

power, and solar power, into electrical energy. The estab-lishments in this industry produce electric energy and pro-vide electricity to transmission systems or to electricpower distribution systems.

221111 Hydroelectric Power Generation

This U.S. industry comprises establishments primarilyengaged in operating hydroelectric power generationfacilities. These facilities use water power to drive a tur-bine and produce electric energy. The electric energy pro-duced in these establishment is provided to electric powertransmission systems or to electric power distribution sys-tems.

The data published with NAICS code 221111 are com-prised of these parts of the following SIC industries:

4911 (pt) Electric services (hydroelectric powergeneration)

4931 (pt) Electric and other services combined(hydroelectric power generation)

4939 (pt) Combination utilities nec (hydroelectricpower generation)

2211111 Electric Services (Hydroelectric PowerGeneration)

Establishments primarily engaged in generating elec-tricity using hydroelectric process. Included are establish-ments that combine pump storage generation processes.

Appendix C.Coverage and Methodology

MAIL/NONMAIL UNIVERSE

For this sector, large- and medium-size firms, plus allfirms known to operate more than one establishment,were sent questionnaires to be completed and returned tothe Census Bureau by mail. For most very small firms datafrom existing administrative records of other Federalagencies were used instead. These records provided basicinformation on location, kind of business, revenue, pay-roll, number of employees, and legal form of organization.

Firms in the 1997 Economic Census were divided intothe mail universe and nonmail universe. The coverage ofand the method of obtaining census information fromeach are described below:

1. The mail universe consisted of firms for which infor-mation was obtained by means of a mail canvass andincluded:

a. Large employers, i.e., all multiestablishment and allsingle-establishment employer firms with payrollabove a specified cutoff. The term ‘‘employers’’refers to firms with one or more paid employees atany time during 1997 as shown in the activeadministrative records of other Federal agencies.

b. A sample of small employers, i.e., single-establishment firms with payroll below a specifiedcutoff, in classifications for which specialized dataprecluded reliance solely on administrative recordssources.

2. The nonmail universe consisted of firms that were notrequired to file a regular census return and included:

a. Selected small employers, i.e., single-establishmentfirms with payroll below a specified cutoff.Although the payroll cutoff varied by kind of busi-ness, small employers in the nonmail universe gen-erally included firms with less than 10 employeesand represented about 10 percent of total revenueof establishments covered in the census. Data onrevenue, payroll, and employment for smallemployers in the nonmail universe were derived orestimated from administrative records of other Fed-eral agencies.

b. All nonemployers, i.e., all firms subject to Federalincome tax with no paid employees during 1997.Revenue information for these firms was obtained

from administrative records of other Federal agen-cies. Although consisting of many firms, nonem-ployers accounted for less than 10 percent of totalrevenue of all establishments covered in the cen-sus. The census included only those nonemployerfirms which reported a revenue volume of $1,000or more during 1997. Data for nonemployers arenot included in this report, but are released as partof the Core Business Statistics Series.

INDUSTRY CLASSIFICATION OF ESTABLISHMENTS

The classifications for all establishments in this sectorwere assigned in accordance with the 1997 North Ameri-can Industry Classification System (NAICS) Manual, UnitedStates. NAICS is a common classification system devel-oped by the United States, Canada, and Mexico. This sys-tem replaces the 1987 Standard Industrial Classification(SIC) that was used in previous censuses. Appendix A ofthe 1997 NAICS manual provides information on the com-parability between the 1987 SIC and the 1997 NAICS.More information on NAICS is available in the NAICSmanual and at www.census.gov/naics.

The method of assigning classifications, and the levelof detail at which establishments were classified, differedbetween the mail and nonmail universe as follows:

1. The mail universe.

a. Establishments in the mail universe that returnedquestionnaires were classified on the basis of theirself-designation, sources of revenue, and otherindustry-specific inquiries.

b. Establishments in the mail universe that did notreturn questionnaires were classified on the basisof the most current census kind-of-business classi-fication available from one of the Census Bureau’scurrent sample surveys, the 1992 census, or theadministrative records of other Federal agencies.

2. The nonmail universe.

a. Employer establishments in the nonmail universewere classified on the basis of the most currentcensus kind-of-business classification availablefrom one of the Census Bureau’s current samplesurveys, the 1992 census, or the administrativerecords of other Federal agencies. If the census or

APPENDIX C C–1UTILITIES


administrative record classifications proved inad-equate (none corresponded to a 1997 census clas-sification in the detail required for employers), thefirm was sent a brief inquiry requesting informationnecessary to assign a 1997 census kind-of-businesscode.

b. Nonemployers were classified on the basis of infor-mation obtained from administrative records ofother Federal agencies.

RELIABILITY OF DATA

All data compiled for this sector are subject to nonsam-pling errors. Nonsampling errors can be attributed tomany sources: inability to identify all cases in the actualuniverse; definition and classification difficulties; differ-ences in the interpretation of questions; errors in record-ing or coding the data obtained; and other errors of collec-tion, response, coverage, processing, and estimation formissing or misreported data.

Data presented in the Miscellaneous Subjects and theSources of Revenue reports for this sector are subject tosampling errors as well as nonsampling errors. Specifi-cally, these data are estimated based on informationobtained from census questionnaires mailed to all largeemployers and to a sample of small employers in the uni-verse. Sampling errors affect these estimates insofar asthey may differ from results that would be obtained froma complete enumeration.

The accuracy of these tabulated data is determined bythe joint effects of the various nonsampling errors or bythe joint effects of sampling and nonsampling errors. Nodirect measurement of these effects has been obtainedexcept for estimation for missing or misreported data;however, precautionary steps were taken in all phases ofthe collection, processing, and tabulation of the data in aneffort to minimize the effects of nonsampling errors.

The Census Bureau obtains limited informationextracted from administrative records of other Federalagencies. This information is used in conjunction withother information available to the Census Bureau to

develop estimates for nonemployers, small employers,and other establishments for which responses were notreceived in time for publication.

TREATMENT OF NONRESPONSE

Census report forms included two different types ofinquiries, ‘‘basic’’ and ‘‘industry-specific.’’ Data for thebasic inquiries, which include location, kind of business oroperation, revenue, payroll, number of employees, andlegal form of organization, were available from a combina-tion of sources for all establishments. Data for industry-specific inquiries, tailored to the particular kinds of busi-ness or operation covered by the report, were availableonly from the establishments in the mail universe thatcompleted the appropriate inquiries on the questionnaire.

Two methods were used to account for nonresponse toindustry-specific inquiries. For some inquiries, missingdata were imputed for individual records based onresponses from similar establishments. For other inquiries,the total of reported data were expanded to represent themail and nonmail universe. Data for industry-specificinquiries based on a December 31 reference date wereexpanded in direct relationship to total annualized rev-enue of only those establishments in business at the endof the year. Unless otherwise noted in specific reports,data for other industry-specific inquiries were expanded indirect relationship to total revenue of all establishmentsincluded in the category. In a few cases, expansion on thebasis of the revenue item was not appropriate, andanother basic data item was used as the basis for expan-sion.

All reports in which data were expanded to account fornonmail employers and nonrespondents include a cover-age indicator for each publication category, which showsthe revenue of establishments responding to the inquiryas a percent of total revenue for all establishments forwhich data are shown. Coverage is usually determined bythe ratio of total revenue of establishments responding tothe inquiry to total revenue of all establishments in thecategory.
