U.S. Census Bureau
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. 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 economic census furnishes an important part of the

framework for such composite measures as the gross

domestic product estimates, input/output measures, production and price indexes, and other statistical series that

measure short-term changes in economic conditions. Specific uses of economic census data include the following:

• Policymaking agencies of the Federal Government use

the data to monitor economic activity and assess the

effectiveness of policies.

• 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, which allows them to 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.

ALL-NEW INDUSTRY CLASSIFICATIONS

Data from the 1997 Economic Census are published primarily on the basis of the North American Industry Classification System (NAICS), unlike earlier censuses, which

were published according to the Standard Industrial Classification (SIC) system. NAICS is in the process of being

adopted in the United States, Canada, and Mexico. Most

economic census reports cover one of the following 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 Foodservices

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.)

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 correspond directly to industries as defined under the SIC system, most of the higher level groupings do not. Particular

care should be taken in comparing data for retail trade,

wholesale trade, and manufacturing, which are sector

titles used in both NAICS and SIC, but cover somewhat different groups of industries. The industry definitions discuss the relationships between NAICS and SIC industries.

Where changes are significant, it will not be possible to

construct time series that include data for points both

before and after 1997.

For 1997, data for auxiliary establishments (those functioning primarily to manage, service, or support the activities of their company’s operating establishments, such as

a central administrative office or warehouse) will not be

included in the sector-specific reports. These data will be

published separately.

GEOGRAPHIC AREA CODING

Accurate and complete information on the physical

location of each establishment is required to tabulate the

census data for the states, metropolitan areas (MAs), counties, parishes, and corporate municipalities including cities, towns, villages, and boroughs. Respondents were

1997 ECONOMIC CENSUS INTRODUCTION 1

U.S. Census Bureau, 1997 Economic Census
required to report their physical location (street address,

municipality, county, and state) if it differed from their

mailing address. For establishments not surveyed by mail

(and those single-establishment companies that did not

provide acceptable information on physical location), location information from Internal Revenue Service tax forms

is used as a basis for coding.

BASIS OF REPORTING

The economic census is conducted on an establishment

basis. A company operating at more than one location is

required to file a separate report for each store, factory,

shop, or other location. Each establishment is assigned a

separate industry classification based on its primary activity and not that of its parent company.

DOLLAR VALUES

All dollar values presented are expressed in current dollars; i.e., 1997 data are expressed in 1997 dollars, and

1992 data, in 1992 dollars. Consequently, when making

comparisons with prior years, users of the data should

consider 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 available

on the Census Bureau Internet site (www.census.gov) and

on compact discs (CD-ROM) for sale by the Census Bureau.

Unlike previous censuses, only selected highlights are

published in printed reports. For more information, including a description of electronic and printed reports being

issued, see the Internet site, or write to U.S. Census

Bureau, Washington, DC 20233-8300, or call Customer

Services at 301-457-4100.

Special Tabulations

Special tabulations of data collected in the 1997 Economic Census may be obtained, depending on availability

of time and personnel, in electronic or tabular form. The

data will be summaries 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) that govern the

regular publications.

Special tabulations are prepared on a cost basis. A

request for a cost estimate, as well as exact specifications

on the type and format of the data to be provided, should

be directed to the Chief of the division named below, U.S.

HISTORICAL INFORMATION

The economic census has been taken as an integrated

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

1954, 1958, and 1963. Prior to that time, individual components of the economic census were taken separately at

varying intervals.

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 the 1840 Decennial Census

and subsequent censuses to include mining and some

commercial activities. The 1905 Manufactures Census was

the first time a census was taken apart from the regular

decennial population census. Censuses covering retail and

wholesale trade and construction industries were added in

1930, as were some covering service trades in 1933. Censuses of construction, manufacturing, and the other business service censuses were suspended during World War

II.

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 range of industries covered in the economic censuses expanded between 1967 and 1992. The census of

construction 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 few

transportation industries were covered as early as 1963, it

was not until 1992 that the census broadened to include

all of transportation, communications, and utilities. Also

new for 1992 was coverage of financial, insurance, and

real estate industries. With these additions, the economic

census and the separate census of governments and census of agriculture collectively covered roughly 98 percent

of all economic activity.

Printed statistical reports from the 1992 and earlier

censuses provide historical figures for the study of longterm time series and are available in some large libraries.

All of the census reports printed since 1967 are still available for sale on microfiche from the Census Bureau.

CD-ROMs issued from the 1987 and 1992 Economic Censuses contain databases including nearly all data published in print, plus additional statistics, such as ZIP Code

statistics, published only on CD-ROM.

U.S. Census Bureau, 1997 Economic Census
Mining

SCOPE

The Mining sector of the 1997 Economic Census covers

all mining establishments of companies with one or more

paid employees. Mining is defined as the extraction of

naturally occurring mineral solids, such as coal and ores;

liquid minerals, such as petroleum;and gases, such as

natural gas. The term mining is used in the broad sense to

include quarrying, well operations, beneficiating (e.g.,

crushing, screening, washing, and floatation), and other

preparations customarily performed at the mine site or as

part of the mining activity.

The Mining sector distinguishes two basic activities:

mine operation and mining support activities. Mine operation includes establishments operating mines, quarries, or

oil and gas wells on their own account or for others on a

contract or fee basis. Mining support activities include

establishments that perform exploration (except geophysical surveying) and/or other mining services on a contract

or fee basis.

Establishments in the Mining sector are classified by

industry according to the natural resources mined or to be

mined. Included are establishments that develop the mine

site, extract the natural resources, and/or those that beneficiate (i.e., prepare) the mineral mined. The operations

that take place in beneficiation are primarily mechanical,

such as grinding, washing, magnetic separation, and centrifugal separation. The range of preparation activities varies by mineral and the purity of any given ore deposit.

Mining, beneficiation, and manufacturing activities

often occur in a single location. Separate receipts are collected for these activities whenever possible. When

receipts cannot be broken out between mining and manufacturing, establishments that mine or quarry nonmetallic

minerals and beneficiate the nonmetallic minerals into

more finished manufactured products are classified based

on the primary activity of the establishment.

Hauling and other transportation beyond the mine

property and contract hauling (except out of open pits in

conjunction with mining) are excluded.

GENERAL

This report, from the 1997 Economic Census – Mining,

is one of a series of 29 industry reports and 51 geographic area reports, each of which provides statistics for

individual industries, states, or offshore areas. Also

included for this sector are the General, Products, and

Materials and Fuels Consumed Summary reports, and data

files on Location of Mining Operations.

Each industry report presents data for a six-digit North

American Industry Classification System (NAICS) industry.

A description of the particular NAICS industry may be

found in Appendix B. These reports include such statistics

as number of establishments, employment, payroll, value

added by mining, cost of supplies used, value of shipments and receipts, capital expenditures, etc., for each

mining industry. Explanations of these and other terms

may be found in Appendix A. The industry reports also

include data for states with 100 employees or more.

State reports present similar statistics at the sector level

for each state, the District of Columbia, and the offshore

areas. The state of Delaware and the District of Columbia

are combined in a single report. The state reports also

include data for industries with 100 employees or more in

the state.

The General Summary report contains industry and geographic area statistics summarized in one report. It

includes higher levels of aggregation than the industry

and state reports as well as revisions to the data made

after the release of the industry and state reports.

The Products Summary and the Materials and Fuels

Consumed Summary reports summarize the products,

materials, and fuels data published in the industry series

reports.

The Location of Mining Operations data files include

statistics on the number of establishments by three- and

six-digit NAICS industry by state and offshore area by

employment size of the establishment.

GEOGRAPHIC AREAS COVERED

The state reports for the mining industries include data

at the state level and some offshore areas. No substate

data are available.

Data for offshore areas that are part of Alaska, California, Louisiana, and Texas are included in their respective

state area reports and represent offshore operations on all

these state offshore leases and all Federal offshore leases

defined by their state plane coordinate systems. State offshore includes the areas extending from the coastline up

to 3 geographical miles distance except for Texas and

Florida which extend 3 marine leagues from the coastline

in the Gulf of Mexico. Data for offshore areas not associated with a state are in an Offshore Areas geographic

report which includes the following areas:

COMPARABILITY OF THE 1992 AND 1997 CENSUSES

The adoption of the North American Industry Classification System (NAICS) has had only a minor effect on the

comparability of data between the 1992 and 1997 censuses at the sector level. However, within the sector the

number of major levels changed from four to three. In

addition, portions of industries left mining for the services

sector. Prominent among items leaving mining are geophysical surveying and mapping services for metal mining, oil and gas, and nonmetallic minerals mining. If industries are not comparable between the two censuses,

historic data are not shown.

Another change resulting from the conversion to NAICS

is that data for central administrative offices (CAOs) associated with mining are no longer included in the mining

data. This change affects all levels of data shown in the

reports.

DISCLOSURE

In accordance with Federal law governing census

reports (Title 13 of the United States Code), no data are

published that would disclose the operations of an individual establishment or company. However, the number of

establishments classified in a specific industry or geography is not considered a disclosure and may be released

even when other information is withheld.

The disclosure analysis for the industry statistics files is

based on the total value of shipments and receipts. When

the total value of shipments and receipts cannot be shown

without disclosing information for individual companies,

the complete line is suppressed except for capital expenditures. If capital expenditures alone is a disclosure, only

capital expenditures and cost of supplies statistics are

suppressed. The suppressed data are included in higherlevel totals.

AVAILABILITY OF MORE FREQUENT ECONOMIC

DATA

The County Business Patterns program of the U.S. Census Bureau offers annual statistics on the number of establishments, employment, and payroll classified by industry

within each county and state.

Explanation of Terms

COST OF SUPPLIES USED, PURCHASED MACHINERY

INSTALLED, ETC.

This term refers to direct charges actually paid or payable for items consumed or put into production during the

year, including freight charges and other direct charges

incurred by the establishment in acquiring these items. It

includes the cost of these items whether purchased by the

individual establishment from other companies, transferred to it from other establishments of the same company, or withdrawn from inventory during the year.

Included are items charged to both current and capital

accounts.

Included in this item are:

1. Costs of supplies used, minerals received for

preparation, and purchased machinery installed.

Includes all major supplies which were important

parts of the cost of production, exploration, and

development of a particular industry.

2. Cost of fuels consumed for heat and power.

Includes the cost of fuel consumed, whether purchased by the individual establishment from other

companies, transferred to it from other establishments

of the same company, or withdrawn from inventory

during the year.

Specific Supplies Used, Minerals Received for

Preparation and Purchased Machinery Installed

In addition to the total cost of supplies, purchased

machinery installed, etc., which every establishment was

required to report, information also was collected on the

consumption of the major supplies used in mining. The

inquiries were restricted to those supplies which were

important parts of the cost of production, exploration, and

development in a particular industry and for which cost

information was available from the establishment’s

records. Except for the crude petroleum and natural gas

and the support activities for mining industries, figures

were also obtained on crude minerals mined at the establishment, received from other establishments of the company or purchased from others, and received for preparation on a custom or toll basis. If less than $25,000 of a

listed supply was consumed by an establishment, the cost

data could be reported in the ‘‘All other supplies...,’’ census supply code 00970098. Also, the cost of supplies for

small establishments for which administrative records or

short forms were used was imputed into the ‘‘Undistributed - minerals, purchased machinery, parts......,’’ census

supply code 00973000.

Specific Fuels Consumed

For most industries, separate quantity and cost figures

are shown for purchased coal, distillate fuel oil, residual

fuel oil, gas, gasoline, and a cost figure for other fuels.

Data also were obtained on the quantity of crude petroleum, natural gas, and coal produced and consumed at the

same establishment for heat and power. The cost of fuels

for small establishments for which administrative records

or short forms were used was imputed into the ‘‘Undistributed fuels,’’ census fuel code 00974000.

NAICS Codes, Titles, and Descriptions

SECTOR 21 MINING

The Mining sector comprises establishments that

extract naturally occurring mineral solids, such as coal

and ores; liquid minerals, such as crude petroleum; and

gases, such as natural gas. The term mining is used in the

broad sense to include quarrying, well operations, beneficiating (e.g., crushing, screening, washing, and flotation),

and other preparation customarily performed at the mine

site, or as a part of mining activity.

The Mining sector distinguishes two basic activities:

mine operation and mining support activities. Mine operation includes establishments operating mines, quarries, or

oil and gas wells on their own account or for others on a

contract or fee basis. Mining support activities include

establishments that perform exploration (except geophysical surveying) and/or other mining services on a contract

or fee basis.

Establishments in the Mining sector are grouped and

classified according to the natural resource mined or to be

mined. Industries include establishments that develop the

mine site, extract the natural resources, and /or those that

beneficiate (i.e., prepare) the mineral mined. Beneficiation

is the process whereby the extracted material is reduced

to particles that can be separated into mineral and waste,

the former suitable for further processing or direct use.

The operations that take place in beneficiation are primarily mechanical, such as grinding, washing, magnetic

separation, and centrifugal separation. In contrast, manufacturing operations primarily use chemical and electrochemical processes, such as electrolysis and distillation.

However some treatments, such as heat treatments, take

place in both the beneficiation and the manufacturing (i.e.,

smelting/refining) stages. The range of preparation activities varies by mineral and the purity of any given ore

deposit. While some minerals, such as petroleum and

natural gas, require little or no preparation, others are

washed and screened, while yet others, such as gold and

silver, can be transformed into bullion before leaving the

mine site.

Mining, beneficiating, and manufacturing activities

often occur in a single location. Separate receipts will be

collected for these activities whenever possible. When

receipts cannot be broken out between mining and manufacturing, establishments that mine or quarry nonmetallic

minerals, beneficiate the nonmetallic minerals into more

finished manufactured products are classified based on

the primary activity of the establishment. A mine that

manufactures a small amount of finished products will be

classified in Sector 21, Mining. An establishment that

mines whose primary output is a more finished manufactured product will be classified in Sector 31-33, Manufacturing.

211 Oil and Gas Extraction

Industries in the Oil and Gas Extraction subsector operate and/or develop oil and gas field properties. Such

activities may include exploration for crude petroleum and

natural gas; drilling, completing, and equipping wells;

operating separators, emulsion breakers, desilting equipment, and field gathering lines for crude petroleum; and

all other activities in the preparation of oil and gas up to

the point of shipment from the producing property. This

subsector includes the production of crude petroleum, the

mining and extraction of oil from oil shale and oil sands,

and the production of natural gas and recovery of hydrocarbon liquids.

Establishments in this subsector include those that

operate oil and gas wells on their own account or for others on a contract or fee basis. Establishments primarily

engaged in providing support services, on a fee or contract basis, required for the drilling or operation of oil and

gas wells (except geophysical surveying and mapping) are

classified in Subsector 213, Support Activities for Mining.

2111 Oil and Gas Extraction

This NAICS Industry Group includes establishments

classified in NAICS Industry 21111, Oil and Gas Extraction.

21111 Oil and Gas Extraction

This industry comprises establishments primarily

engaged in operating and/or developing oil and gas field

properties and establishments primarily engaged in recovering liquid hydrocarbons from oil and gas field gases.

Such activities may include exploration for crude petroleum and natural gas; drilling, completing, and equipping

wells; operation of separators, emulsion breakers, desilting equipment, and field gathering lines for crude petroleum; and all other activities in the preparation of oil and

gas up to the point of shipment from the producing property. This industry includes the production of crude petroleum, the mining and extraction of oil from oil shale and

oil sands, the production of natural gas and the recovery

of hydrocarbon liquids from oil and gas field gases. Establishments in this industry operate oil and gas wells on

their own account or for others on a contract or fee basis.

212 Mining (Except Oil and Gas)

Industries in the Mining (except Oil and Gas) subsector

primarily engage in mining, mine site development, and

in the broad sense to include ore extraction, quarrying,

and beneficiating (e.g., crushing, screening, washing, sizing, concentrating, and flotation), customarily done at the

mine site.

Beneficiation is the process whereby the extracted

material is reduced to particles which can be separated

into mineral and waste, the former suitable for further

processing or direct use. The operations that take place in

beneficiation are primarily mechanical, such as grinding,

washing, magnetic separation, centrifugal separation, and

so on. In contrast, manufacturing operations primarily use

chemical and electrochemical processes, such as electrolysis, distillation, and so on. However some treatments,

such as heat treatments, take place in both stages:the

beneficiation and the manufacturing (i.e., smelting/ refining) stages. The range of preparation activities varies by

mineral and the purity of any given ore deposit. While

some minerals, such as petroleum and natural gas, require

little or no preparation, others are washed and screened,

while yet others, such as gold and silver, can be transformed into bullion before leaving the mine site.

Establishments in the Mining (except Oil and Gas) subsector include those that have complete responsibility for

operating mines and quarries (except oil and gas wells)

and those that operate mines and quarries (except oil and

gas wells) for others on a contract or fee basis. Establishments primarily engaged in providing support services, on

Coverage and Methodology

MAIL/NONMAIL UNIVERSE

The mining universe includes about 25,000 establishments. This number includes those industries in the NAICS

definition of mining, but not those portions of industries

leaving the mining sector in the classification change. The

amounts of information requested from mining establishments were dependent on a number of factors. The most

important consideration was the size of the company. The

methods of obtaining information for the various subsets

of the universe to arrive at the aggregate figures shown in

the publication are described below:

1. Small single-establishment companies not sent a

report form.

Approximately 40 percent of the mining establishments were small single-establishment companies that

were excused from filing a census report. Selection of

these establishments was based on two factors:

annual payroll and our ability to assign the correct sixdigit NAICS industry classification to the establishment. For each four-digit Standard Industrial Classification (SIC) industry code, an annual payroll cut-off

was determined. These cutoffs were derived so that

the establishments with payroll less than the cutoff

were expected to account for no more than 3 percent

of the value of shipments and receipts for the industry. Generally, all single-establishment companies with

less than 5 employees were excused, while all establishments with more than 20 employees were mailed

forms. Establishments below the cutoff that could not

be directly assigned a six-digit NAICS code were

mailed a classification report which requested information for assigning NAICS industry codes. Establishments below the cut-off that could be directly

assigned a six-digit NAICS code were excused from

filing any report. For below-cut-off establishments,

information on the physical location, payroll, and

receipts was obtained from the administrative records

of other Federal agencies under special arrangements

which safeguarded their confidentiality.

Estimates of data for these small establishments

were developed using industry averages in conjunction with the administrative information. The value of

shipments and receipts, cost of supplies, etc., and

cost of fuels were not distributed among specific

products, supplies, and fuels for these establishments

but were included in the product, supplies, and fuels

‘‘not specified by kind’’ (nsk) categories.

The industry classification codes included in the

administrative-record files were assigned on the basis

of brief descriptions of the general activity of the

establishment. As a result, an indeterminate number

of establishments were erroneously coded to a fourdigit SIC industry and then erroneously recoded to a

six-digit NAICS industry. This was especially true

whenever there was a relatively fine line of demarcation between industries or between mining and nonmining activity.

Sometimes the administrative-record cases had

only two- or three-digit SIC group classification codes

available in the files. For the 1997 Economic Census–

Mining, these establishments were sent a separate

classification form, which requested information on

the products and services of the establishment. This

form was used to code many of these establishments

to the appropriate six-digit NAICS level. Establishments that did not return the classification form were

coded later to those six-digit NAICS industries identified as a default within the given subsector.

As a result of these situations, a number of small

establishments may have been misclassified by industry. However, such possible misclassification has no

significant effect on the statistics other than on the

number of companies and establishments.

The total establishment count for individual industries should be viewed as an approximation rather

than a precise measurement. The counts for establishments with 20 employees or more are far more reliable than the count of total number of establishments.

2. Establishments sent a report form.

The establishments covered in the mail canvass

were divided into two groups:

a. Large and medium size establishments.

Approximately 48 percent of all mining establishments were included in this group. A variable

cutoff, based on administrative-record payroll data

and determined on an industry-by-industry basis,

was used to select those establishments that were

to receive 1 of the 10 economic census – mining

regular forms. The first four pages, requesting

establishment data for items, such as employment

and payroll, costs, assets, and capital expenditures,

were fairly standard although some variation

occurred depending on the industries collected on

1997 ECONOMIC CENSUS APPENDIX C C–1

U.S. Census Bureau, 1997 Economic Census
the form. The remaining pages of the form contained product, supply, fuel, and special inquiries.

The diversity of the mining activities necessitated

the use of several forms to canvass the 29 mining

industries. Most forms were developed for a group

of industries.

b. Small single-establishment companies.

This group included approximately 12 percent of

all mining establishments. For those industries

where application of the variable cutoff for

administrative-record cases resulted in a large number of small establishments being included in the

mail canvass, an abbreviated or short form was

used. Establishments in the crushed stone, sand

and gravel, and crude petroleum and natural gas

industries with 5 to 19 employees received 1 of 2

versions of the short form. The form requested

summary product and material data and totals but

no details on payrolls, cost of supplies and fuels,

assets, and capital expenditures.

Use of the short form has no adverse effect on

published totals for the industry statistics because

the same data were collected on the short form as

on the long form. However, detailed information on

supplies and fuels was not collected on the short

form; thus, its use would increase the value of the

nsk categories.

INDUSTRY CLASSIFICATION OF ESTABLISHMENTS

Each of the establishments covered in the 1997 Economic Census – Mining was classified in 1 of 29 mineral

industries in accordance with the industry definitions in

the 1997 NAICS manual. This is the first edition of the

NAICS manual and is a major change from the 1987 SIC

manual that was used in the past. Appendix A of the 1997

NAICS manual notes the comparability between the 1987

SIC and the 1997 NAICS classification systems. When

applicable, Appendix G of this report shows the product

comparability between the two systems for the data in

this report.

In the NAICS system, an industry is generally defined as

establishments grouped according to similarity in the processes used to produce the mineral products. To the

extent practical, the system uses supply-based or

production-oriented concepts in defining industries. The

resulting group of establishments must be significant in

terms of its number, value added by mining, value of shipments and receipts, number of employees, and payroll.

The coding system works in such a way that the definitions progressively become narrower with successive

additions of numerical digits. In the mining sector for

1997, there are 3 subsectors (three-digit NAICS), 5 industry groups (four-digit NAICS), and 10 NAICS industries

(5-digit NAICS) that are comparable with Canadian and

Mexican classification and 29 U.S. industries (six-digit

NAICS). This represents a slight reduction of the four-digit

SIC-based U.S. industries from 31 in 1987. Within industries, there are 141 seven-digit product classes and 196

ten-digit products. The ten-digit products are considered

the primary products of the industry with the same first

six digits.

For the 1997 Economic Census – Mining, all establishments were classified in particular industries based on the

products they produced. If an establishment made products of more than one industry, it was classified in the

industry with the largest product value.

Establishments frequently make products classified

both in their industry (primary products) and other industries (secondary products). Industry statistics (employment, payroll, value added by mining, value of shipments

and receipts, etc.) reflect the activities of the establishments which may make both primary and secondary products. Product statistics, however, represent the output of

all establishments without regard for the classification of

the producing establishment. For this reason, when relating the industry statistics (especially the value of shipments and receipts) to the product statistics, the composition of the industry’s output should be considered.

ESTABLISHMENT BASIS OF REPORTING

The 1997 Economic Census – Mining covers each mining establishment of firms with one or more paid employees operating in the United States. A company operating

more than one establishment is required to file a separate

report for each location. A mining establishment is defined

as a single physical location where mineral operations are

conducted. However, a company engaged in distinctly different lines of activity at one location is required to submit

a separate report for each activity if the plant records permit such a separation and if the activities are substantial

in size.

For oil and gas field operations and for contract services, the basis for reporting is different from the ‘‘establishment’’ basis used for other types of mining. Firms

operating oil and gas wells, drilling wells, or exploring for

oil and gas for their own account were required to submit

a separate report for each state or offshore area adjacent

to a state in which it conducted such activities. Firms that

performed contract services for oil and gas field operations or for mining establishments were required to submit one report covering all such activities in the United

States and to include information on receipts for services

and production-worker wages and hours by state. These

consolidated reports were then allocated to state establishments based on the data reported at the state level.

The 1997 figures for establishments include the summation of operations for each state allocated from these

nationwide reports.

In the 1997 Economic Census – Mining, as in censuses

since 1967, data for single-unit firms without paid

employees were excluded. This exclusion had only a slight

C–2 APPENDIX C 1997 ECONOMIC CENSUS

U.S. Census Bureau, 1997 Economic Census
effect on industry aggregates for most industries. Data for

firms without employees were included in the 1963, 1958,

and 1954 censuses if they reported more than $500 in (1)

value of shipments and receipts, (2) cost of supplies and

purchased machinery, or (3) capital expenditures.

The 1997 Economic Census – Mining excludes data for

central administrative offices. Statistics for employment

and payroll for individual industries and industry groups

no longer include employment and payroll figures for

administrative offices, warehouses, storage facilities, and

other auxiliary establishments servicing mining establishments. These data are included in a separate report series.

DUPLICATION IN COST OF MATERIALS AND VALUE

OF SHIPMENTS

Data for cost of materials and value of shipments

include varying amounts of duplication, especially at

higher levels of aggregation. This is because the products

of one establishment may be the materials of another. The

value added statistics avoid this duplication and are, for

most purposes, the best measure for comparing the relative economic importance of industries and geographic

areas.

VALUE OF INDUSTRY SHIPMENTS COMPARED WITH

VALUE OF PRODUCT SHIPMENTS

The 1997 Economic Census – Mining shows value of

shipments and receipts data for industries and products.

In the industry statistics tables and files, these data represent the total value of shipments of all establishments

classified in a particular industry. The data include the

shipments of the products classified in the industry (primary to the industry), products classified in other industries (secondary to the industry), and miscellaneous

receipts (repair work, sale of scrap, research and development, installation receipts, and resales). Value of product

shipments shown in the products statistics tables and files

represent the total value of all products shipped that are

classified as primary to an industry regardless of the classification of the producing establishment. The value of

products shipped also may include some products shipped

from manufacturing establishments with mining operations.
