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

to 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.

INDUSTRY CLASSIFICATIONS

Data from the 2002 Economic Census are published primarily according to the 2002 North American Industry Classification System (NAICS). NAICS was first adopted in the United States, Canada,

and Mexico in 1997. The 2002 Economic Census covers 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 Food Services

81 Other Services (except Public Administration)

(Not listed above are the Agriculture, Forestry, Fishing, and Hunting sector (NAICS 11), partially

covered by the census of agriculture conducted by the U.S. Department of Agriculture, and the

Public Administration sector (NAICS 92), largely covered by the census of governments conducted

by the Census Bureau.)

The 20 NAICS sectors are subdivided into 100 subsectors (three-digit codes), 317 industry groups

(four-digit codes), and, as implemented in the United States, 1,179 industries (six-digit codes).

2002 Economic Census Introduction v

U.S. Census Bureau, 2002 Economic Census
RELATIONSHIP TO HISTORICAL INDUSTRY CLASSIFICATIONS

Prior to the 1997 Economic Census, data were published according to the Standard Industrial Classification (SIC) system. 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

1997 Economic Census Bridge Between NAICS and SIC demonstrates the relationships between

NAICS and SIC industries. Where changes are significant, it may not be possible to construct time

series that include data for points both before and after 1997.

Most industry classifications remained unchanged between 1997 and 2002, but NAICS 2002

includes substantial revisions within the construction and wholesale trade sectors, and a number

of revisions for the retail trade and information sectors. These changes are noted in industry definitions and will be demonstrated in the Bridge Between NAICS 2002 and NAICS 1997.

For 2002, data for enterprise support establishments (those functioning primarily to support the

activities of their company’s operating establishments, such as a warehouse or a research and

development laboratory) are included in the industry that reflects their activities (such as warehousing). For 1997, such establishments were termed auxiliaries and were excluded from industry

totals.

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. (For selected industries, only payroll, employment, and classification are collected for individual establishments, while other data are collected on a consolidated

basis.)

GEOGRAPHIC AREA CODING

Accurate and complete information on the physical location of each establishment is required to

tabulate the census data for states, metropolitan and micropolitan statistical areas, counties, and

corporate municipalities (places) including cities, towns, townships, villages, and boroughs.

Respondents were 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 administrative sources is used as a basis for coding.

AVAILABILITY OF ADDITIONAL DATA

All results of the 2002 Economic Census are available on the Census Bureau Internet site

(www.census.gov) and on digital versatile discs (DVD-ROMs) for sale by the Census Bureau. The

American FactFinder system at the Internet site allows selective retrieval and downloading of the

data. For more information, including a description of reports being issued, see the Internet site,

write to the U.S. Census Bureau, Washington, DC 20233-6100, or call Customer Services at 301-

763-4100.

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

vi Introduction 2002 Economic Census

U.S. Census Bureau, 2002 Economic Census
from the regular decennial population census. Censuses covering retail and wholesale trade and

construction industries were added in 1930, as were some service trades in 1933. Censuses of

construction, manufacturing, and the other business 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 and 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 report forms.

The range of industries covered in the economic census expanded between 1967 and 2002. 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. New for 2002 is coverage of four industries classified in the agriculture,

forestry, and fishing sector under the SIC system: landscape architectural services, landscaping

services, veterinary services, and pet care services.

Printed statistical reports from the 1992 and earlier censuses provide historical figures for the

study of long-term time series and are available in some large libraries. Reports for 1997 were

published primarily on the Internet and copies of 1992 reports are also available there. CD-ROMs

issued from the 1987, 1992, and 1997 Economic Censuses contain databases that include all or

nearly all data published in print, plus additional statistics, such as ZIP Code statistics, published

only on CD-ROM.

U.S. Census Bureau, 2002 Economic Census
Mining

SCOPE

The Mining sector (sector 21) 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 (except mine site preparation and construction of oil/gas pipelines).

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.

Exclusions. Hauling and other transportation beyond the mine property and contract hauling

(except out of open pits in conjunction with mining).

The tabulations for this sector do not include central administrative offices, warehouses, or other

establishments that serve mining establishments within the same organization. Data for such

establishments are classified according to the nature of the service they provide. For example,

separate headquarters establishments are reported in NAICS Sector 55, Management of Companies and Enterprises.

The reports described below exclude establishments of firms with no paid employees. These

“nonemployers,” typically self-employed individuals or partnerships operating businesses that

they have not chosen to incorporate, are reported separately in Nonemployer Statistics. The contribution of nonemployers, relatively moderate for this sector, may be examined at

www.census.gov/nonemployerimpact.

2002 Economic Census Mining ix

U.S. Census Bureau, 2002 Economic Census
The reports described below cover all mining establishments with one or more paid employees.

Definitions. Industry categories are defined in Appendix B, NAICS Codes, Titles, and Descriptions. Other terms are defined in Appendix A, Explanation of Terms.

REPORTS

The following reports provide statistics on this sector:

Industry Series. There are 29 reports, each covering a single NAICS industry (six-digit code).

These reports include such statistics as number of establishments, employment, payroll, value

added by mining, cost of supplies, value of shipments and receipts for services, capital expenditures, etc. The industry reports also include data for states with 100 employees or more in the

industry. The data in industry reports are preliminary and subject to change in the following

reports.

Geographic Area Series. There are 52 separate reports, one for each state, the District of

Columbia, and offshore areas. Each state report presents similar statistics at the “all mining” level

for each state. The state reports also include six-digit NAICS level data for industries with 100

employees or more in the state.

Subject Series:

• Industry-Product Analysis Summary. This report presents value of shipments and receipts

for services, value of product shipments or receipts for services, percentage of product shipments of the total value of shipments and receipts for services, and percentage of distribution

of value of product shipments or receipts for services on the NAICS six-digit industry level and

by the six- and seven-digit product code levels. It also includes miscellaneous receipts at the

six- and seven-digit product code levels by NAICS six-digit industry levels.

• General Summary. This 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.

• Product Summary. This report summarizes the products data published in the industry

reports.

• Materials Summary. This report summarizes the materials and fuels data published in the

industry reports.

• Location of Mines Summary. This report contains statistics on the number of establishments

for the three- and six-digit NAICS industry by state and offshore area by employment-size of the

establishment.

Other reports. Data for this sector are also included in reports with multisector coverage, including Nonemployer Statistics, Comparative Statistics, Bridge Between 2002 NAICS and 1997 NAICS,

Business Expenses, and the Survey of Business Owners reports.

GEOGRAPHIC AREAS COVERED

1. The United States as a whole.

2. States and the District of Columbia.

3. Offshore Areas. 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

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 that includes the following areas:

x Mining 2002 Economic Census

b. Northern Gulf of Mexico Offshore: Northern Gulf of Mexico Federal Areas defined by the

Universal Transverse Mercator Coordinate System (including areas generally south of the

state plane coordinate systems of Louisiana and Texas), Mississippi state offshore, Alabama state offshore, and Florida state Gulf offshore.

c. Pacific Offshore: Pacific Federal areas defined by Universal Transverse Mercator Coordinate

System, Oregon state offshore, and Washington state offshore.

DOLLAR VALUES

All dollar values presented are expressed in current dollars; i.e., 2002 data are expressed in 2002

dollars, and 1997 data, in 1997 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.

COMPARABILITY OF THE 1997 AND 2002 ECONOMIC CENSUSES

Both the 2002 Economic Census and the 1997 Economic Census present data based on the North

American Industry Classification System (NAICS). There were several revisions to selected industries in the mining sector, for 2002. These changes were due to industries that are now being classified in the construction sector. These changes are:

• 213112 – Construction of field gathering lines on a contract basis

• 213112 – Site preparation and related construction activities on a contract basis

• 213113 – Site preparation and related construction activities on a contract basis

• 213114 – Site preparation and related construction activities on a contract basis

• 213115 – Site preparation and related construction activities on a contract basis

More detailed information of NAICS changes from 1997 to 2002, may be examined at

www.census.gov/epcd/naics02/n02ton97.htm.

In addition, there have been several additional data tables added, which did not exist in 1997.

These tables for 2002 include industry-product analysis, e-commerce value of shipments and

receipts for services, and leased and nonleased detail employment statistics by subsectors.

RELIABILITY OF DATA

All data compiled for this sector are subject to nonsampling errors. Nonsampling errors can be

attributed to many sources: inability to identify all cases in the actual universe; definition and

classification difficulties; differences in the interpretation of questions; errors in recording or coding the data obtained; and other errors of collection, response, coverage, processing, and estimation for missing or misreported data.

No direct measurement of these effects has been obtained except for estimation for missing or

misreported data, as by the percentages shown in the tables. Precautionary steps were taken in all

phases of the collection, processing, and tabulation of the data in an effort to minimize the effects

of nonsampling errors. More information on the reliability of the data is included in Appendix C,

Methodology.

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 in a specific industry or geographic area is not considered

a disclosure; therefore, this information may be released even though other information is withheld. Techniques employed to limit disclosure are discussed at

www.census.gov/epcd/ec02/disclosure.htm.

The disclosure analysis for “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. Nonetheless, the suppressed data are included in higher-level totals.

AVAILABILITY OF MORE FREQUENT ECONOMIC DATA

The County Business Patterns program offers annual statistics on the number of establishments,

employment, and payroll classified by industry within each county, and Statistics of U.S. Businesses provides annual statistics classified by the employment size of the enterprise, further classified by industry for the United States, and by broader categories for states and metropolitan

areas.

U.S. Census Bureau, 2002 Economic Census
Appendix A.

Explanation of Terms

COMPANY

A company or “enterprise” is comprised of all the establishments that operate under the ownership or control of a single organization. A company may be a business, service, or membership

organization; consist of one or several establishments; and operate at one or several locations. It

includes all subsidiary organizations, all establishments that are majority-owned by the company

or any subsidiary, and all the establishments that can be directed or managed by the company or

any subsidiary.

A company may have one or many establishments. Examples include product and service sales

offices (retail and wholesale), industrial production plants, processing or assembly operations,

mines or well sites, and support operations (such as an administrative office, warehouse, customer service center, or regional headquarters). Each establishment should receive, complete, and

return a separate census form.

If the company operated at different physical locations, even if the individual locations were producing the same mineral product, a separate report was requested for each location. If the company operated in two or more distinct lines of mining at the same location, a separate report was

requested for each activity.

Establishment

An establishment is a single physical location where business is conducted or where services or

industrial operations are performed. Data in this sector includes those establishments where mineral operations are performed. A separate report was required for each mining establishment of

firms with one employee or more that was in operation at any time during the year.

An establishment not in operation for any portion of the year was requested to return the report

form with the proper notation in the “Operational Status” section of the form. In addition, the

establishment was requested to report data on any employees, capital expenditures, inventories,

or shipments from inventories during the year.

For the crude petroleum and support activities for mining industries, the basis for reporting is different from the establishments’ 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 operation 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.

TOTAL VALUE OF SHIPMENTS AND RECEIPTS FOR SERVICES

Includes the net selling values, “Free on Board” (FOB) mine or plant after discounts and allowances

(exclusive of freight and excise taxes), of all products shipped, both primary and secondary, as

well as all miscellaneous receipts, such as installation and repair, sales of scrap, and sales of products bought and sold without further processing. Included are all products physically shipped by

the establishments, whether sold, transferred to other plants of the same company, or shipped on

consignment. For products transferred to other establishments of the same company, or prepared

on a custom or toll basis, companies were requested to report the estimated value, not merely the

cost of producing the product.

Mining Appendix A A–1

U.S. Census Bureau, 2002 Economic Census
In the case of multiunit companies, the mineral operation was requested to report the value of

products transferred to other establishments of the same company at full economic or commercial

value, including not only the direct cost of production but also a reasonable proportion of “all

other costs” (including company overhead) and profit.

In addition to the value for NAICS defined products, aggregates of the following categories of miscellaneous receipts are reported as part of a total establishment’s value of shipments and receipts

for services:

1. Receipts for services — receipts for work or services that an establishment performed for others.

2. Value of resales — sales of products brought and sold without further processing.

3. Other miscellaneous receipts — includes repair work, installation, sales of scrap, etc.

Industry primary product value of shipments and receipts for services represents one of three

components of value of shipments and receipts for services. These components are:

1. Primary product value of shipments and receipts for services.

2. Secondary product value of shipments and receipts for services.

3. Value of resales.

An establishment is classified in a particular NAICS industry when its shipments of a particular

group of products exceed in value its shipments of products classified in any other single industry.

An establishment’s value of shipments and receipts for services include those products assigned

to an industry (primary products), those considered primary to other industries (secondary products), receipts for services and miscellaneous activities, and the value of resales.

Value of product shipments represents the total value of all products shipped that are classified as

primary to an industry and includes those that were shipped by all mining and manufacturing

establishments regardless of their industry classification.

Duplication in cost of supplies, etc., and value of shipments and receipts for

services

The aggregate of the cost of supplies, etc., and value of shipments and receipts for services figures for industry groups and all mining industries includes some duplication since the products of

some industries are used as supplies by others. Some duplication exists because of the inclusion

of minerals transferred from one establishment to another for mineral preparation or resale.

Duplication may also exist within the products of some individual industries where minerals

shipped for preparation are also reported as the prepared product by another establishment.

VALUE OF PRODUCT SHIPMENTS OR RECEIPTS FOR SERVICES

Includes the total value of all products shipped that are classified as primary to an industry and

includes those that were shipped by all mining and manufacturing establishments regardless of

their industry classification.

PRODUCT SHIPMENTS OR RECEIPTS FOR SERVICES AS PERCENT OF TOTAL VALUE OF

SHIPMENTS AND RECEIPTS FOR SERVICES

Includes the percentage of the value of product shipments or receipts for services at the six- and

seven-digit NAICS levels over the total value of shipments and receipts for services for the specified industry.

A–2 Appendix A Mining

Methodology

SOURCES OF THE DATA

The mining sector includes approximately 25,000 establishments. This number includes those

industries in the North American Industry Classification System (NAICS) definition of mining. The

amount of information requested from mining establishments was dependent upon a number of

factors. The more important consideration was the size of the company.

Establishments in the 2002 Economic Census are divided into those sent report forms and those

not sent report forms. The coverage of and the method of obtaining census information from each

are described below:

1. Establishments sent a report form:

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 15 economic census — mining regular forms. The

first seven 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 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.

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 products, supplies, and fuels was not collected on the short form;

thus, its use would increase the value of the “not specified by kind” (nsk) categories.

2. Establishments not sent a report form:

a. 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 the Census Bureau’s ability to assign the correct six-digit NAICS industry

classification to the establishment. For each six-digit NAICS industry code, an annual payroll cutoff 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 that requested information for assigning NAICS industry codes. Establishments below the cutoff that could be

Mining Appendix C C–1

U.S. Census Bureau, 2002 Economic Census
directly assigned a six-digit NAICS code were excused from filing any report. For below cutoff establishments, information on the physical location, payroll, and receipts was obtained

from the administrative records of other federal agencies under special arrangements that

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 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 NAICS group classification codes available in the files. For 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 sixdigit NAICS level. Establishments that did not return the classification form were coded

later to those six-digit NAICS industries identified as “All other,” 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.

b. All nonemployers, i.e., all firms subject to federal income tax, with no paid employees, during 2002 are excluded as in previous censuses. Data for nonemployers are not included in

this report, but are released in the annual Nonemployer Statistics series.

The report forms used to collect information for establishments in this sector are available at

help.econ.census.gov/econhelp/resources/.

A more detailed examination of census methodology is presented in the History of the Economic

Census at www.census.gov/econ/www/history.html.

INDUSTRY CLASSIFICATION OF ESTABLISHMENTS

The classifications for all establishments covered in the 2002 Economic Census — Mining are classified in 1 of 29 industries in accordance with the industry definitions in the North American

Industry Classification System, (NAICS), United States, 2002 manual. Changes between 1997 and

2002 affecting this sector are discussed in the text at the beginning of this report. Tables at

www.census.gov/epcd/naics02/ identify those industries that changed between the 1997 North

American Industry Classification System (NAICS) and 2002 NAICS. When applicable, Appendix F of

this report shows the product class and product comparability between the two systems for data

in this report.

In the NAICS system, an industry is generally defined as a group of establishments that have similar 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.

C–2 Appendix C Mining

U.S. Census Bureau, 2002 Economic Census
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 2002, there are 3 subsectors

(three-digit NAICS), 5 industry groups (four-digit NAICS), 10 NAICS industries (five-digit NAICS)

that are comparable with Canadian and Mexican classification, and 29 U.S. industries (six-digit

NAICS). Product classes and products of the mining industries have been assigned codes based on

the industry from which they originate. There are 63 product classes (seven-digit codes) and 136

ten-digit product codes. The ten-digit products are considered the primary products of the industry with the same first six digits.

For the 2002 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 that 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 2002 Economic Census — Mining covers each mining establishment of firms with one or

more paid employees operating in the United States. A company operating at 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, 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 2002 figures for establishments include the summation of operations for each

state allocated from these nationwide reports.

In 2002, as in prior censuses since 1967, data for single-unit firms without paid employees were

excluded. This exclusion had only a slight 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 2002 Economic Census — Mining excludes data for central administrative offices (CAOs).

These would include separately operated administrative offices, warehouses, garages, and other

auxiliary units that service mining establishments of the same company. These data are published

in a separate report series.

RELIABILITY OF DATA

All data compiled in the economic census are subject to nonsampling errors. Nonsampling errors

can be attributed to many sources during the development or execution of the census:

• inability to identify all cases in the actual universe;

• definition and classification difficulties;

Mining Appendix C C–3

U.S. Census Bureau, 2002 Economic Census
• differences in the interpretation of questions;

• errors in recording or coding the data obtained; and

• other errors of collection, response, coverage, processing, and estimation for missing or misreported data.

The Census Bureau obtains limited information extracted from administrative records of other federal agencies, such as gross receipts from federal income tax records and employment and payroll

from payroll tax records. This information is used in conjunction with other information available

to the Census Bureau to develop estimates for nonemployers, small employers, and other establishments for which responses were not received in time for publication.

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 2002 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.

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 in a specific industry or geographic area is not considered

a disclosure; therefore, this information may be released even though other information is withheld. Techniques employed to limit disclosure are discussed at

www.census.gov/epcd/ec02/disclosure.htm.

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. Nonetheless, the suppressed data are included in higher-level totals.
