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.

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.

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 are

published in printed reports. For more information, includ-ing a description of electronic and printed reports beingissued, see the Internet site, or write to U.S. CensusBureau, Washington, DC 20233-8300, or call CustomerServices at 301-457-4100.

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 1810

Decennial 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 be

fully 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.

1997 Commodity Flow Survey

GENERAL

The 1997 Commodity Flow Survey (CFS) is undertakenthrough a partnership between the Bureau of the Census,U.S. Department of Commerce, and the Bureau of Trans-portation Statistics, U.S. Department of Transportation.This survey produces data on the movement of goods inthe United States. It provides information on commoditiesshipped, their value, weight, and mode of transportation,as well as the origin and destination of shipments ofmanufacturing, mining, wholesale, and selected retailestablishments. The CFS was last conducted in 1993. Seethe Comparability With the 1993 Commodity Flow Surveytable (Appendix A) for a comparison between the 1997and 1993 surveys. The data from the CFS are used by pub-lic policy analysts and for transportation planning anddecision-making to assess the demand for transportationfacilities and services, energy use, and safety risk andenvironmental concerns.

This report presents data on Metropolitan Area (MA)and Remainder of State (ROS) shipment characteristics.Additional reports include data for the United States, Cen-sus Regions, Divisions, states, hazardous material ship-ments, as well as selected data on exports.

METROPOLITAN AREA AND REMAINDER OF STATE

Data are provided for 86 selected Metropolitan Areas(MA) and Remainder of States (ROS). The Census Bureauand Bureau of Transportation Statistics (BTS) selectedthese MAs based on population counts from the 1996 Cur-rent Population Survey (CPS). For the purposes of the Com-modity Flow Survey (CFS), these MAs are confined withinstate boundaries.

Please note:

This report presents data for selected major met-ropolitan areas (MAs) confined within state bound-aries. Data are also presented for Remainder ofState (ROS) . ROS is defined as the portion of a statenot included in any of the selected major MAs. Alist of counties comprising each MA and ROS isprovided on the CFS Internet site at:www.census.gov/econ/www/cfsmain.html.

METROPOLITAN AREA DEFINITIONS

The general concept of a MA is that of a core area con-taining a large population nucleus, together with adjacentcommunities that have a high degree of economic and

social integration with that core. The Federal Office ofManagement and Budget (OMB), designates and definesMAs following a set of official standards. (The MA stan-dards for the 1990s were published in the Federal Registeron March 30, 1990 B Vol. 55, No. 62, pp. 12154-12160.)The MA classification is provided for use by Federal agen-cies in the production, analysis, and publication of data.

Included among MAs are metropolitan statistical areas(MSAs), consolidated metropolitan statistical areas(CMSAs), and primary metropolitan statistical areas(PMSAs). In additional, New England county metropolitanareas (NECMAs) are an alternative set of areas defined forthe six New England states.

METROPOLITAN STATISTICAL AREAS

An MSA consists of one or more counties that contain acity of 50,000 or more inhabitants, or contain a CensusBureau defined urbanized area (UA) and have a total popu-lation of at least 100,000 (75,000 in New England). Coun-ties containing the principal concentration of population -the largest city and surrounding densely settled area arecomponents of the MSA. Additional counties qualify to beincluded by meeting a specified level of commuting to thecounties containing the population concentration and bymeeting certain other requirements of metropolitan char-acter, such as a specified minimum population density orpercentage of the population that is urban. MSAs in NewEngland are defined in terms of cities and towns, follow-ing rules concerning commuting and population density.

CONSOLIDATED METROPOLITAN STATISTICALAREAS

An area that meets the requirements to qualify as anMSA and also has a population of 1 million or morebecomes a CMSA if component parts of the area are recog-nized as PMSAs.

PRIMARY METROPOLITAN STATISTICAL AREAS

Subareas may be defined within an area that meets therequirements to qualify as an MSA and also has a popula-tion of 1 million or more. The definition of these subareascalled PMSAs requires meeting specified statistical criteriaand have the support of local opinion. A PMSA consists of

a large urbanized county or a cluster of counties (citiesand towns in New England) that demonstrate strong inter-nal economic and social links in addition to close ties withthe central core of the larger area. Upon the recognition ofPMSAs, the entire area of which they are parts becomes aCMSA. All territory within a CMSA is also within somePMSA.

NEW ENGLAND COUNTY METROPOLITAN AREAS

NECMAs are county based alternatives to the city- andtown-based MSAs and CMSAs in the six New Englandstates. The county composition of a NECMA reflects thegeographic extent of the corresponding MSAs or CMSAs.NECMAs are not defined for individual PMSAs.

MODES

Single modes for these reports are aggregatedas follows:

Truck (includes shipments which went by private truck,for-hire truck only, or a combination of private truck andfor-hire truck).

Rail.

All other single modes (includes water, air, and pipe-line).

STANDARD CLASSIFICATION OF TRANSPORTEDGOODS (SCTG) CODES

The SCTG codes for the Metropolitan Area and Remain-der of State Reports are aggregated into nine commoditygroupings. The following describes the two-digit SCTGsincluded in each commodity grouping:

INDUSTRY COVERAGE

The 1997 CFS covers business establishments in min-ing, manufacturing, wholesale trade, and selected retailindustries. The survey also covers selected auxiliary estab-lishments (e.g., warehouses) of in-scope multiunit andretail companies. The survey coverage excludes establish-ments classified as farms, forestry, fisheries, govern-ments, construction, transportation, foreign establish-ments, services, and most establishments in retail.

The industries covered, as defined in the 1987 StandardIndustrial Classification Manual (SIC), are listed in thefollowing table:

SIC code Title

10, ex. 108 Metal mining (excluding metal mining services)12, ex. 124 Coal mining (excluding coal mining services)

13 Oil and gas extraction1

14, ex. 148 Mining and quarrying of nonmetallic minerals,except fuels (excluding nonmetallic mineralsservices)

20 Food and kindred products21 Tobacco products22 Textile mill products23 Apparel and other finished products made from

fabrics and similar materials24 Lumber and wood products, except furniture25 Furniture and fixtures26 Paper and allied products27, ex. 279 Printing, publishing, and allied industries

(excluding service industries for theprinting trade)

28 Chemicals and allied products29 Petroleum refining and related industries

30 Rubber and miscellaneous plastics products31 Leather and leather products32 Stone, clay, glass, and concrete products33 Primary metal industries34 Fabricated metal products, except machinery

and transportation equipment35 Industrial and commercial machinery and

computer equipment36 Electronic and other electrical equipment and

components, except computer equipment37 Transportation equipment38 Measuring, analyzing, and controlling

instruments; photographic, medical andoptical goods; watches and clocks

39 Miscellaneous manufacturing industries

50 Wholesale trade—durable goods51 Wholesale trade—nondurable goods

596 Catalog and mail-order houses

1We included establishments classified in SIC 13, Oil and GasExtraction, in the initial coverage of the 1997 CFS. However, becauseof unresolved industry-wide reporting issues, we have removed ship-ments from these establishments from our 1997 CFS tabulations. Thedata collected from these establishments will be used as input to a spe-cial report at a later date.

Similarly, because establishments in SIC 13 are responsible for theoverwhelming number of shipments classified in SCTG 16, CrudePetroleum, we have removed all shipments with SCTG 16 from the1997 CFS publication results.

SHIPMENT COVERAGE

The CFS captures data on shipments originating fromselected types of business establishments located in the50 states and the District of Columbia. The data do notcover shipments originating from business establishmentslocated in Puerto Rico and other U.S. possessions and ter-ritories. Shipments traversing the U.S. from a foreign loca-tion to another foreign location (e.g., from Canada toMexico) are not included, nor are shipments from a for-eign location to a U.S. location. Imported products areincluded in the CFS at the point that they left the import-er’s domestic location for shipment to another location.Shipments that are shipped through a foreign territorywith both the origin and destination in the U.S. areincluded in the CFS data. The mileages calculated for theseshipments exclude the international segments (e.g., ship-ments from New York to Michigan through Canada do notinclude any mileages for Canada). Export shipments areincluded, with the domestic destination defined as theport of exit from the U.S.

The ‘‘Industry Coverage’’ section of the text lists the SICgroups covered by the CFS. Other industry areas that arenot covered, but may have significant shipping activity,include agriculture, government, and retail (other thanwarehouses and SIC 5961, Catalog and Mail-OrderHouses). For agriculture specifically, this means that theCFS did not cover shipments of agricultural products fromthe farm site to the processing centers or terminal eleva-tors (most likely short-distance local movements), butdoes cover the shipments of these products from the ini-tial processing centers or terminal elevators onward.

MILEAGE CALCULATIONS

To compute shipment mileages for the 1997 CFS, TheCenter for Transportation Analysis (CTA) at Oak RidgeNational Laboratory (ORNL) developed an integrated, inter-modal transportation network modeling system. A securedata site was setup at ORNL to process census-suppliedfiles containing data elements for individual CFS shipmentrecords. Each record contained the ZIP Code of shipmentorigin and destination, and the mode or mode sequencereported. Each record also contained information on thetype of commodity moved, its weight, dollar value andwhether containerized or a hazardous material. Exportshipments were also identified on the records, along withdata on U.S. port of exit and foreign destination city andcountry. Encrypted data files were transmitted andreturned from ORNL after processing, with turnaround ofmost files on a week-by-week basis. In this manner manyshipment-specific data problems encountered by ORNL intheir routing procedures were reported back to census in atimely fashion, allowing census to call back some shippersand thereby confirm, correct, or recover missing or other-wise unusable data. The ORNL system computed mile-ages, by mode, for all single modes and for any reported

multimodal sequence. This was done for any origin-destination pair of domestic ZIP Code locations, and forany internal ZIP Code of origin, via U.S. export port, to for-eign (export) destination. Mileages between origin-destination ZIP Code centroids were computed by findingthe minimum impedance path over mathematical repre-sentations of the highway, rail, waterway, air, and pipelinenetworks and then summing the lengths of individuallinks on these paths. Impedance is computed as aweighted combination of distance, time, and cost factors.

The ORNL multimodal network database is composedof individual modal-specific networks representing each ofthe major transportation modes—highway, rail, waterway,air, and pipeline. The links of these specific modal net-works are the representation of line-haul transportationfacilities. The nodes represent intersections and inter-changes, and the access points to the transportation net-work. To simulate local access, test links are created fromeach five-digit ZIP Code centroid to nearby nodes on thenetwork. For the truck network, local access is assumed toexist everywhere. For the other modes this is not true.Before any test links are created for these modes, a searchprocedure is used to determine if and where such net-works are most likely to provide access to the ZIP Code.For shipments involving more than one mode, such astruck-rail or rail-water shipments, intermodal transfer linksare added to the network database for the purpose of con-necting the individual modal networks together for rout-ing purposes. An intermodal terminals database and anumber of terminal transfer models were developed atORNL to identify likely transfer points for different classesof freight. A measure of link impedance was calculated foreach access, line-haul, and intermodal transfer link tra-versed by a shipment. These impedances were mode spe-cific and are based on various link characteristics. Forexample, the set of link characteristics for the highwaynetwork included speed impacting factors, such as thepresence of divided or undivided roadway, the degree ofaccess control, rural or urban setting, type of pavement,number of lanes, degree of urban congestion, and lengthof the link. Link impedance measures are also assigned tothe local access links. Intermodal transfer link impedancesare estimated in terms of the time it takes to move goodsthrough such a transfer. In the case of rail and air freight,intercarrier transfer penalties are also considered in orderto obtain proper route selections. A minimum path algo-rithm is used to find the minimum impedance pathbetween a shipment’s origin ZIP Code centroid and desti-nation ZIP Code centroid. The cumulative length of thelocal access plus line-haul links on this path provides theestimated shipment distance. When rail was involvedthese shipment distances may be averaged over morethan one path between an origin-destination pair.

Mileage Data for Pipeline Shipments

In the tables, we do not show ton-miles or averagemiles per shipment for pipeline shipments. For most ofthese shipments, the respondents reported the shipment

destination as a pipeline facility on the main pipeline net-work. Therefore, for the majority of these shipments, theresulting mileage represented only the access distancethrough feeder pipelines to the main pipeline network,and not the actual distance through the main pipeline net-work. Pipeline shipments are included in the U.S. totals forton-miles and average miles per shipment.

DISCLOSURE RULES

In accordance with Federal law governing CensusBureau reports, no data are published that would disclosethe operations of an individual firm or establishment.

EXPLANATION OF TERMS

Average miles per shipment. For the 1993 CFS, weexcluded shipments of STCC 27, Printed Matter, from ourcalculation of average miles per shipment. We made thisdecision after determining that respondents in the 1993CFS shipping newspapers, magazines, catalogs, etc., hadused widely varying definitions of the term ‘‘shipment.’’

For the 1997 CFS, we made numerous efforts through-out our data collection and editing to produce consistentresults from establishments shipping SCTG 29, PrintedProducts. As a result, we have included printed productsin the average miles per shipment calculations for the1997 CFS.

Commodity. Products that an establishment produces,sells, or distributes. This does not include items that areconsidered as excess or byproducts of the establishment’soperation. Respondents reported the description and thefive-digit SCTG code for the major commodity contained inthe shipment, defined as the commodity with the greatestweight in the total shipment.

Distance shipped. In some tables, shipment data arepresented for various ‘‘distance shipped’’ intervals. Ship-ments were categorized into these ‘‘distance shipped’’intervals based on the great circle distance between theirorigin and destination ZIP Code centroids. All otherdistance-related data in this and other tables (i.e., ton-miles and average miles per shipment) are based on themileage calculations produced by Oak Ridge NationalLaboratories. (See the ‘‘Mileage Calculations’’ section formore details.)

Great circle distance. The shortest distance betweentwo points on the earth’s surface.

Mode of transportation. The type of transportationused for moving the shipment to its domestic destination.For exports, the domestic destination was the port of exit.

Mode Definitions

In the instructions to the respondent, we defined thepossible modes as follows:

4. Railroad. Any common carrier or private railroad.

5. Shallow draft vessels. Barges, ships, or ferries oper-ating primarily on rivers and canals; in harbors, theGreat Lakes, the Saint Lawrence Seaway; the Intrac-oastal Waterway, the Inside Passage to Alaska, majorbays and inlets; or in the ocean close to the shoreline.

6. Deep draft vessel. Barges, ships, or ferries operat-ing primarily in the open ocean. Shipping on the GreatLakes and the Saint Lawrence Seaway is classified withshallow draft vessels.

7. Pipeline. Movements of oil, petroleum, gas, slurry,etc., through pipelines that extend to other establish-ments or locations beyond the shipper’s establish-ment. Aqueducts for the movement of water are notincluded.

8. Air. Commercial or private aircraft, and all air servicefor shipments that typically weigh more than 100pounds. Includes air freight and air express.

9. Other mode. Any mode not listed above.

10. Unknown. The shipment was not carried by a parceldelivery/courier/U.S. Postal Service, and the respon-dent could not determine what mode of transportationwas used.

In the tables, we have used additional terms for mode,which we define as follows:

1. Air (includes truck and air). Shipments that usedair or a combination of truck and air.

2. Single modes. Shipments using only one of theabove-listed modes, except parcel or other andunknown.

3. Multiple modes. Parcel, U.S. Postal Service or couriershipments or shipments for which two or more of thefollowing modes of transportation were used:

Private truckFor-hire truckRailShallow draft vesselDeep draft vesselPipeline

We did not allow for multiple modes in combinationwith ‘‘parcel, U.S. Postal Service or courier,’’‘‘unknown,’’ or ‘‘other.’’ By their nature, these ship-ments may already include various kinds of multiple-mode activity. For example, if the respondent reporteda shipment’s mode of transportation as parcel and air,we treated the shipment as parcel only.

4. Other multiple modes. Shipments using any othermode combinations not specifically listed in thetables.

5. Other and unknown modes. Shipments for whichmodes were not reported, or were reported by therespondent as ‘‘Other’’ or ‘‘Unknown.’’

6. Truck. Shipments using for-hire truck only, privatetruck only, or a combination of for-hire truck and pri-vate truck.

7. Water. Shipments using shallow draft vessel only,deep draft vessel only, or Great Lakes vessel only.Combinations of these modes, such as shallow draftvessel and Great Lakes vessel are included as ‘‘Othermultiple modes.’’

8. Great Lakes. In the tables in this publication, ‘‘GreatLakes’’ appears as a single mode. ORNL’s transporta-tion network and mileage calculation system allowedfor separate mileage calculations for Great Lakesbetween the origin and destination ZIP Codes (see the‘‘Mileage Calculations’’ section for more details).

Other Definitions and Terms

Shipment. A shipment (or delivery) is an individual move-ment of commodities from an establishment to a customeror to another location of the originating company (includ-ing a warehouse, distribution center, retail or wholesaleoutlet). A shipment uses one or more modes of transporta-tion including parcel delivery, U.S. Postal Service, courier,private truck, for-hire truck, rail, water, pipeline, air, andother modes.

Standard Classification of Transported Goods(SCTG). The commodities shown in this report are classi-fied using the SCTG coding system. The SCTG coding sys-tem was developed jointly by agencies of the UnitedStates and Canadian governments based on the Harmo-nized System to address statistical needs in regard toproducts transported.

Ton-miles. The weight times the mileage for a shipment.The respondents reported shipment weight in pounds, asdescribed below. Mileage was calculated as the distancebetween the shipment origin and destination ZIP Codes.For shipments by truck, rail, or shallow draft vessels, themileage excludes international segments. For example,mileages from Alaska to the continental United States

exclude any mileages through Canada (see the ‘‘MileageCalculations’’ section for more details). Aggregated pound-miles were converted to ton-miles. The ton-miles data aredisplayed in millions.

Tons shipped. The total weight of the entire shipment.Respondents reported the weight in pounds. Aggregatedpounds were converted to short-tons (2,000 pounds). Thetons data are displayed in thousands.

Total modal activity. The overall activity (e.g., ton-miles)of a specific mode of transportation, whether used in asingle-mode shipment, or as part of a multiple-mode ship-ment. For example, the total modal activity for privatetruck is the total ton-miles carried by private truck insingle-mode shipments, combined with the total ton-milescarried by private truck in all multiple-mode shipmentsthat include private truck (private truck and for-hire truck,private truck and rail, private truck and air, etc.)

Value of shipments. The dollar value of the entire ship-ment. This was defined as the net selling value, f.o.b.plant, exclusive of freight charges and excise taxes. Thevalue data are displayed in millions of dollars.

Appendix A.Comparability With the 1993 Commodity Flow Survey

The Commodity Flow Survey (CFS) restores a data pro-gram on commodity flows that the Census Bureau con-ducted as a part of its 5-year economic census programfrom 1963 through 1977. The CFS was first conducted in

1993. For the 1997 CFS, the Census Bureau incorporatedimprovements identified from the evaluation of previoussurveys and additional research. The following tableshows a comparison of the 1993 and 1997 surveys.

Appendix B.Reliability of the Estimates

An estimate based on a sample survey potentially con-tains two types of errors—sampling and nonsampling.Sampling error occurs because characteristics differamong sampling units and because only a subset of theentire population is measured in a sample survey. Non-sampling error encompasses all other factors that contrib-ute to the total error of a sample survey estimate. Theaccuracy of a survey result may be affected by these twotypes of errors.

Sampling and nonsampling errors are often measuredby the quantities, bias and variance. The bias of an esti-mator of an unknown population value is the difference,averaged over all possible samples of the same size anddesign, between the estimator and the unknown popula-tion value. Any systematic error, or inaccuracy that affectsall samples of a specified design in a similar way, may biasthe resulting estimates. Variance is the squared difference,averaged over all possible samples of the same size anddesign, between an estimator and its average value.Descriptions of sampling and nonsampling errors for the1997 Commodity Flow Survey (CFS) are provided in thefollowing sections.

SAMPLING ERROR

Because the estimates are based on a sample, exactagreement with the results that would be obtained from acomplete enumeration of all the shipments made in 1997from all establishments included on the CFS samplingframe is not expected. However, because probability sam-pling was used at each stage of selection, it is possible toestimate the sampling variability of the survey estimates.For CFS estimates, sampling variability arises from each ofthe three stages of sampling. (See Appendix C for adescription of the sample design.)

The particular sample used in this survey is one of alarge number of samples of the same size and design thatcould have been selected. If all possible samples had beensurveyed, under the same conditions, an estimate of anunknown population value could have been obtained fromeach sample. The estimates obtained from these samplesgive rise to a distribution of estimates for the unknownpopulation value. A statistical measure of the variabilityamong these estimates is the standard error, which can beapproximated from any one sample. The coefficient ofvariation (or relative standard error) of an estimate is thestandard error of the estimate divided by the estimate.Measures of sampling variability, such as the standarderror or coefficient of variation, are estimated from the

sample and are also subject to sampling variability. (Tech-nically, we should refer to the estimated standard error orthe estimated coefficient of variation of an estimator. How-ever, we have omitted this detail for the sake of brevity.) Itis important to note that the standard error and coefficientof variation only measure sampling variability. They donot measure any biases in the estimates. All coefficients ofvariation are expressed as percents. Standard errors forthe corresponding percentage estimates are also provided.

An estimate of an unknown population value and itsapproximate standard error can be used to construct aconfidence interval. A confidence interval is a range abouta given estimator that has a specified probability, or confi-dence, of containing the unknown population value. If, foreach possible sample, an estimate of an unknown popula-tion value and the estimate’s approximate standard errorwere obtained, then:

1. For approximately 90 percent of the possible samples,the interval from 1.65 standard errors below to 1.65standard errors above the estimate would include theunknown population value.

2. For approximately 95 percent of the possible samples,the interval from two standard errors below to twostandard errors above the estimate would include theunknown population value.

NONSAMPLING ERROR

Nonsampling error encompasses all other factors thatcontribute to the total error of a sample survey estimateand may also occur in censuses. It is often helpful to thinkof nonsampling error as arising from deficiencies or mis-takes in the survey process. In the CFS, nonsampling errorcan be attributed to many sources: (1) nonresponse, (2)response errors, (3) differences in the interpretation of thequestions, (4) mistakes in coding or keying the dataobtained, and (5) other errors of collection, response, cov-erage, and processing. Although no direct measurement ofthe potential biases because of nonsampling error hasbeen obtained, precautionary steps were taken in allphases of the collection, processing, and tabulation of thedata in an effort to minimize its influence.

A potentially large source of bias in the estimates is dueto nonresponse. Nonresponse is defined as the inability toobtain all the intended measurements or responses fromall the selected establishments. Four levels of nonre-sponse can occur in the CFS: item, shipment, quarter(reporting week), and establishment. Item nonresponse

occurs either when a question is unanswered or theresponse to the question fails computer or analyst edits.Item nonresponse is corrected by imputation. (Imputationis the procedure by which a missing value is replaced by apredicted value obtained from an appropriate model.)Shipment, quarter, and establishment nonresponse areused to describe the inability to obtain sufficient informa-tion about a sampled shipment, quarter, or establishment,respectively, that prevents it from contributing to tabula-tions. Shipment and quarter nonresponse are correctedduring the estimation procedure by reweighting.Reweighting allocates characteristics to the nonrespon-dents in proportion to the characteristics observed for therespondents. The amount of bias introduced by this non-response adjustment procedure depends on the extent towhich the nonrespondents differ, characteristically, fromthe respondents. Establishment nonresponse is correctedduring the estimation procedure by the SIC-level adjust-ment weight. (See Appendix C for a description of the esti-mation procedure.) In most cases of establishment nonre-sponse, none of the four questionnaires have been

returned to the Census Bureau, after several attempts toelicit a response. Approximately 67 percent of thesampled establishments provided at least one quarter ofdata that contributed to tabulations.

Some possible sources of bias that are attributed torespondent-conducted sampling include misunderstandingthe definition of a shipment, constructing an incompleteframe of shipments from which to sample, ordering theshipment sampling frame by selected shipment character-istics, and selecting shipment records by a method otherthan the one specified in the questionnaire’s instructions.We often contacted respondents who reported shipmentshaving atypically large value or weight when compared tothe rest of their reported shipments. Upon contact, if weare able to collect information on all of a given respon-dent’s large shipments made either for a particular report-ing week or for the entire quarter, then we identify theselarge shipments as certainty shipments. (See Appendix Cfor a description of how certainty shipments are used inthe estimation process.)

Appendix C.Sample Design, Data Collection, and Estimation

INTRODUCTION

The primary goal for the 1997 Commodity Flow Survey(CFS) is to estimate shipping volumes (value, tons, andton-miles) by commodity and mode of transportation atvarying levels of geographic detail. A detailed descriptionof the sample design for the 1997 CFS is provided below.

SAMPLE DESIGN

The sample for the 1997 CFS is selected using a strati-fied three-stage design in which the first-stage samplingunits are establishments, the second-stage sampling unitsare groups of four 1-week periods (reporting weeks)within the survey year, and the third-stage sampling unitsare shipments.

First Stage

To create the first-stage sampling frame, we extracted asubset of establishment records from the 1995 StandardStatistical Establishment List (SSEL). The SSEL is a data-base, maintained by the Bureau of the Census, that con-tains a record for each establishment with employees. (Anestablishment is a single physical location where businesstransactions take place.) Establishments having nonzeropayroll in 1994 and classified in the mining, manufactur-ing, wholesale, or selected retail industries, as defined bythe 1987 Standard Industrial Classification (SIC) Manual,are included on the sampling frame. Auxiliary establish-ments (e.g. warehouses and central administrative offices)with shipping activity are also included. Auxiliary estab-lishments are establishments that are primarily involved inrendering support services for other establishments withinthe same company, instead of for the public, government,or other business firms. All other establishments con-tained on the sampling frame are referred to as nonauxil-iary establishments. For each establishment we extractedsales, payroll, number of employees, name and addressinformation, as well as a primary identifier. We also com-puted a measure of size for each establishment. The mea-sure of size for a particular establishment is designed toapproximate the establishment’s total value of shipmentsfor 1994.

To reduce the amount of sampling variability andbecause estimates are desired for each commodity, weused a stratified design with a certainty component foreach three-digit SIC. To accomplish this, each establish-ment on the sampling frame is classified into a three-digit

SIC grouping. For each group of establishments, a bound-ary (or cutoff) that divides the certainty establishmentsfrom the noncertainty establishments is determined usingthe Lavallee-Hidiroglou algorithm. If an establishment’smeasure of size is greater than the cutoff, the establish-ment is selected ‘‘with certainty’’. Establishments selected‘‘with certainty’’ were assured of being selected and repre-sented only themselves (i.e., have a selection probabilityof one and a sampling weight of one). No certainty cutoffsare set for auxiliary establishments because they onlymake up a small portion of the estimated total value ofshipments for all establishments on the sampling frame.

Establishments not selected with certainty makeup thenoncertainty universe. We stratify the noncertainty uni-verse by SIC recode, National Transportation AnalysisRegion (NTAR), and a flag used to differentiate auxiliaryestablishments from nonauxiliary establishments. Each SICrecode is constructed from a group of related three-digitSIC codes. The NTARs, developed by the Department ofTransportation as combinations of Bureau of EconomicAnalysis (BEA) Areas, collectively provide a mutually exclu-sive and exhaustive coverage of the United States. Finally,the auxiliary stratification came about because establish-ments with different types of operation may have differentshipping practices. We refer to a particular SIC recode-NTAR-auxiliary flag combination as a primary stratum.

We further stratify the noncertainty establishmentswithin each primary stratum using the measure of sizepreviously described. We refer to these measure-of-sizestrata as substrata of the primary strata. The measure ofsize stratification increases the efficiency of the sampledesign. The Dalenius-Hodges cumulative rule is used toset the substratum boundaries. We then use Neyman allo-cation to determine the sample size required within eachsubstratum to meet a coefficient of variation constraint onthe primary stratum total measure of size. Within eachsubstratum, a simple random sample of establishments isselected without replacement.

To arrive at the final sample size, we allocated addi-tional establishments to some of the strata so that theprobability of selecting any establishment is no less than 1in 100. In total, the first-stage sample comprises 102,739establishments.

Second Stage

The frame for the second stage of sampling consists of52 one-week reporting periods (reporting weeks) duringthe interval from December 29, 1996, to December 26,

1997. Each establishment selected for the 1997 CFS wassystematically assigned to report for a group of fourreporting weeks throughout the survey year. The fourreporting weeks in a given group are separated by 12weeks. For example, an establishment might be requestedto report data for the 5th, 18th, 31st, and 44th weeks ofthe survey year.

Third Stage

For each of the four reporting weeks in which an estab-lishment is asked to report, we request the respondent toconstruct a sampling frame that consists of all shipmentsmade by their establishment in each particular reportingweek. For any particular reporting week, if an establish-ment makes 40 or fewer shipments during that week, weask the respondent to provide information about all oftheir establishment’s shipments from that week, i.e., nosampling is required. For establishments making morethan 40 shipments in a given reporting week, we ask therespondent to select a systematic sample of these ship-ments and to provide us with information only about theselected shipments. The size of a particular respondent’ssample for a given reporting week should be between 20and 40 shipments, depending on the total number of ship-ments the establishment made during that reportingweek.

DATA COLLECTION

Each establishment selected into the CFS sample ismailed a questionnaire for each of its four reportingweeks. For a given establishment, we request the respon-dent to provide the following information about theirestablishment’s shipments: domestic destination or portof exit, commodity, value, weight, mode(s) of transporta-tion, the date on which the shipment was made, and anindication of whether the shipment was an export, hazard-ous material, or containerized. For shipments that includemore than one commodity, respondents are instructed toreport the commodity that makes up the greatest percent-age of the shipment’s weight. For exports, we also ask therespondent to provide the mode of export and the foreigndestination city and country.

We used two versions of the questionnaire to collectdata from the sampled establishments—the CFS-1000 andthe CFS-2000. Each establishment received the CFS-1000in each of its first three reporting weeks. However, for thefourth reporting week, a subsample of approximately25,000 establishments received the CFS-2000, while theremaining establishments received the CFS-1000. The CFS-2000 requests the respondent to provide additional infor-mation about their establishment’s access to on-site andoff-site shipping facilities, as well as transportation equip-ment. See Appendix E for a copy of each questionnaire.

ESTIMATION

Each shipment has associated with it a single tabulationweight, that is used in computing all estimates to which

the shipment contributes. The tabulation weight is a prod-uct of seven different weights. A description of eachweight follows.

CFS respondents provide data for a sample of ship-ments made by their respective establishments in the sur-vey year. For each establishment, we produce an estimateof that establishment’s total value of shipments for theentire survey year. To do this, we use four differentweights, the shipment weight, the shipment nonresponseweight, the quarter weight, and the quarter nonresponseweight.

Like establishments, we identify shipments as eithercertainty or noncertainty. (See the Nonsampling Error sec-tion in Appendix B for a description of how certainty ship-ments are identified.) For noncertainty shipments, theshipment weight is defined as the ratio of the total num-ber of noncertainty shipments (as reported by the respon-dent) made by an establishment in a reporting week to thenumber of sampled noncertainty shipments for the sameweek. This weight uses the data from the sampled ship-ments to represent all the establishment’s shipmentsmade in the reporting week. However, some respondentsfail to provide sufficient information about a sampledshipment. For example, a respondent may not be able toprovide value, weight, or a destination ZIP Code for someof the sampled shipments. If these data items cannot beimputed, then these shipments would not contribute totabulations and are deemed ‘‘unusable.’’ (A usable ship-ment is one that has valid entries for value, weight, andorigin and destination ZIP Codes.) To account for these‘‘unusable’’ shipments, we apply the shipment nonre-sponse weight. For noncertainty shipments from a particu-lar establishment’s reporting week, this weight is equal tothe ratio of the number of sampled shipments for thereporting week to the number of ‘‘usable’’ shipments forthe same week. The shipment weight and shipment nonre-sponse weight for certainty shipments from a particularestablishment’s reporting week are both equal to one.

The quarter weight inflates an establishment’s estimatefor a particular reporting week to an estimate for the cor-responding quarter. For noncertainty shipments, the quar-ter weight is equal to 13. The quarter weight for most cer-tainty shipments is also equal to 13. However, if arespondent is able to provide information about all large(or certainty) shipments made in the quarter containingthe reporting week, then the quarter weight for each ofthese shipments would be one. For each establishment,the quarterly estimates are added to produce an estimateof the establishment’s value of shipments for the entiresurvey year. Whenever an establishment does not providethe Census Bureau with a response for each of its fourreporting weeks, we compute a quarter nonresponseweight. The quarter nonresponse weight for a particularestablishment is defined as the ratio of the number of

quarters for which the establishment was in business inthe survey year to the total number of quarters (reportingweeks) for which we received usable shipment data fromthe establishment.

Using these four component weights, we compute anestimate of each establishment’s value of shipments forthe entire survey year. We then multiply this estimate by aweight that adjusts the estimate using value of shipmentsand sales data obtained from other Census Bureau surveysand preliminary results of the 1997 Economic Census.This weight, called the establishment-level adjustmentweight, attempts to correct for any sampling or nonsam-pling errors that occur during the sampling of shipmentsby the respondent.

The adjusted value of shipments estimate for an estab-lishment is then weighted by the establishment weight.This weight is equal to the inverse of the establishment’sprobability of being selected into the sample.

A final adjustment weight, called the SIC-level adjust-ment weight, uses preliminary results of the 1997 Eco-nomic Census to account for establishments from whichwe did not receive a response (including establishmentsfrom which we did not receive any usable shipment data)and for changes in the population of establishmentsbetween the time the first-stage sampling frame was con-structed (1995) and the year in which the data were col-lected (1997). Separate SIC-level adjustment weights aredetermined for nonauxiliary and auxiliary establishments.

Appendix D.Standard Classification of Transported Goods CodeInformation

The commodities shown in this report are classifiedusing the Standard Classification of Transported Goods(SCTG) coding system. The SCTG coding system was cre-ated jointly by agencies of the United States and Canadiangovernments based on the Harmonized System (HS) ofproduct classification which is used worldwide. The pur-pose of the SCTG coding system was to specificallyaddress statistical needs in regard to products trans-ported.In the past, Commodity Flow Survey (CFS) data have

been collected and reported using product classificationsfound in the Standard Transportation Commodity Classifi-cation (STCC) system. These classifications were devel-oped in the early 1960s by the American Association ofRailroads (AAR) to analyze commodity movements by rail.The original purpose of the STCC was for identification ofcommodities for purposes of assigning rates for InterstateCommerce Commission (ICC) regulated rail carriers. TheSTCC continues to be used by the AAR as a tariff mecha-nism.At the time that the Commodity Transportation Survey

(CTS) (the CTS—the predecessor of the CFS) was first con-ducted in 1963, STCC codes were still useful for analyzingmost important aspects of the U.S. transportation system.Since then, many changes have taken place that havegradually made the STCC code less useful for trackingdomestic product movements across all modes (although

it remains perfectly functional for tracking rail-only move-ments). These include the deregulation of trucking, theenactment of North American Free Trade Agreement(NAFTA), changes in logistics practices, the emergence ofplastics and composite materials to replace metals andglass, the obsolescence of many categories of wood prod-ucts, and the very rapid recent development of high-techelectronic goods. Because the CFS is a shipper survey, theCFS collects information about shipments moving on allmodes. As a consequence, STCC classifications frequentlyprovide inadequate detail for identifying products that aresignificant for modes, such as truck and air. It is for thesereasons that the Bureau of Transportation Statistics (BTS)has sponsored the development of a new product code tocollect and report CFS data.In 1997 the CFS provided respondents with a listing of

SCTG codes and descriptions at the five-digit level to usein assigning a commodity code for each shipment. Forshipments of more than one commodity, we instructedrespondents to use the five-digit code for the major com-modity, defined as the commodity of greatest total weightin the shipment.Additional information on the SCTG system can be

found on the Internet through the BTS web page athttp://www.bts.gov. Comments or questions on the SCTGshould be directed to http://[email protected].

What we mean by a "shipment":

For the purposes of this survey, a shipment is a single movement of goods,commodities, products, etc. from your location to a customer or to anotherlocation of your company.

Do not include as shipments items such as inter-office memos, payroll checks,business correspondence, etc.

Do not include as shipments items such as refuse, scrap paper, waste, andrecyclable materials unless your location is in the business of selling orproviding these materials to others.

A special note about "shipments":

A full, or partial, truckload should be counted as a single shipment only if allthe commodities on the truck are destined for one location.If a truck makes multiple deliveries on a route, please count each stop asone shipment.

Item E: Sampling Instructions

If you reported 40 or fewer shipments in Item D, complete Item F (ShipmentCharacteristics) for all of your shipments covered by the one-week reportingperiod.

If you reported more than 40 shipments in Item D, follow the instructions inItem E in order to select a sample of shipments on which to report in Item F.

By asking you to select a sample of your shipments for the one-weekreporting period, we avoid asking you for information on all yourshipments, while still obtaining statistically accurate information.
