NAICS and U.S. Statistics


The North American Industry Classification System (NAICS) is the first-ever uniform system of North American industry classifications. It replaces the 1987 U.S. Standard Industrial Classification (SIC) system that has been used in the United States to present statistical information since the 1930's. NAICS was developed by the Economic Classification Policy Committee (ECPC) of the United States, on behalf of the Office of Management and Budget, in cooperation with Statistics Canada and Mexico's Instituto Nacional de Estadística, Geografía e Informática (INEGI) to provide a consistent framework for the collection, analysis and dissemination of industry statistics used by government policy analysts, academics and researchers, the business community, and the public. This paper focuses on the development of NAICS-based statistics at the Census Bureau and the issues surrounding the transition from the SIC to NAICS.


Over the past decade, the SIC had come under increasing criticism. The system was developed in the 1930's when manufacturing industries were the most important component of the Gross Domestic Product (GDP). Of the 1004 industries recognized in the SIC, almost half (459) represent manufacturing industries even though the manufacturing component of GDP has shrunk to under 20 percent. On the other hand, service industries were considerably under- represented in the classification system. Many important and growing service industries were combined into not elsewhere classified categories. For example, one of the fastest growing U.S. service industries over the past several years was SIC 7389, Business Services, Not Elsewhere Classified.

NAICS was developed based on an economic concept. Establishments are grouped together into industries based on the production processes used to produce a good or service. The development of a classification system based on a consistent economic principle ensures that consistent statistics across the three countries can be produced and used for measuring productivity and unit labor costs, constructing input-output tables, and other uses that imply the analysis of production relationships in the economy.

A number of objectives of NAICS were outlined by the statistical agencies of the three countries in an agreement published in a July 26 1994, Federal Register notice. Those included developing a system (1) based on an economic concept; (2) focused on new and emerging industries, industries engaged in the production of advanced technologies, and service industries; and (3) improving comparability with the International Standard Industrial Classification System (ISIC), developed and maintained by the United Nations Statistical Office.

NAICS is a six-digit classification system that provides for three country comparability at the five-digit industry level. The NAICS agreement among the three countries states that each country may develop additional industries below the five-digit level (six-digit national industries) to recognize important national industries as long as those national industries fit within the framework of the five-digit system. The United States has developed a number of six-digit industries to further delineate NAICS and provide data on important U.S. industries.

Major Changes in NAICS

NAICS is a complete restructuring of the 1987 SIC. Nine new service sectors and 358 new industries are recognized in NAICS United States, 250 of which are service industries. There are 20 sectors delineated in NAICS; the SIC had 10 divisions. Attachment A shows the NAICS sectors and the number of subsectors, industry groups, NAICS industries, and U.S. industries. Below is a brief outline of the major changes in NAICS.


Economic Census

The first major statistical program in the U.S. statistical system to implement NAICS is the Census Bureau's 1997 Economic Census. As with past SIC revisions, the economic census forms for 1997 were mailed based on the SIC code retained in the Census Bureau's Standard Statistical Establishment List. The forms received by the companies included 1987 SIC codes, but also included requests for the additional information needed by the Census Bureau to assign an SIC and a NAICS code to the business establishment. This procedure allows Census to provide to the data user information on both an SIC and NAICS basis so that a "bridge" between the two systems is available for analysts. Following is an explanation of the information to be published in the Economic Census and the dates for release:

Advance Report (presents information at the NAICS 3- and 4-digit level for all sectors covered by the census. Data also will be shown on an SIC basis at the 2- and 3-digit level for all sectors). 1st quarter 1999
Industry, Geographic, and Subject reports for all sectors (NAICS only) beginning 2nd quarter 1999
Comparative Statistics (SIC only) - presents 4-digit SIC data for all sectors 1st quarter 2000
Bridge Between NAICS and SIC (tables show each 4-digit SIC and its 6-digit NAICS components; and each 6-digit NAICS industry and its 4-digit SIC components) 1st quarter 2000
Nonemployer Statistics (NAICS only) - presents information on 14 million businesses with no paid employees 3rd quarter 2000

To produce complete data, the Economic Census relies heavily on the administrative records of other government agencies. Of the 21 million businesses in the United States, forms were sent to only 5 million business locations. Internal Revenue Service (IRS) data were used in lieu of direct reporting for 1.7 million small employer businesses and 14 million businesses with no paid employees (nonemployers). Because IRS is not coding businesses to a NAICS basis until tax year 1998, Census had to use special procedures to ensure proper NAICS coding for all businesses in 1997. For those small employers whose SIC code did not directly convert to a NAICS code, a special classification form was mailed to assign the proper NAICS code.

For those 14 million businesses with no paid employees, a two-phase process is being used to assign NAICS codes.

Because modeling will be employed for some percent of nonemployer establishments, the Census Bureau plans to publish information for nonemployers at the national and state level only. No substate data will be available for 1997. Plans are to publish nonemployer estimates for 1997 on a NAICS basis only.

Current Economic Programs

Implementing NAICS in the Economic Census is an enormous, difficult undertaking. The sheer size of the census and the need to recode every business establishment in the United States to a NAICS basis makes the task daunting. In addition, many decisions on census form design and coverage had to be made even before the NAICS development work was completed. These problems, however, pale in comparison to the problems and issues associated with implementing NAICS in the current economic programs of the Census Bureau. The diversity of the program, type of sampling units surveyed, time series needs, and continued funding constraints pose serious questions on how to ensure a smooth transition for both the data user and data provider. The underlying strategy for implementation is built on the Economic Census as the framework. Implementing NAICS is a top priority of the Economic Directorate of the Census Bureau and all plans center around the 1997 Economic Census providing the benchmark for NAICS-based statistics.

Issues related to NAICS implementation in the current programs that are presently being addressed by the Economic Directorate at the Census Bureau include the following:

The Economic Directorate has established an interdirectorate team to coordinate NAICS activities across the directorate. Six working groups are focusing on the above issues to develop a plan that will ensure a systematic approach to implementing NAICS.

Content Issues

Because NAICS completely restructures the SIC, major changes must be made to the current economic statistics programs. Those surveys most affected are the M3 and the current services surveys, including the retail sales and wholesale trade economic indicators. We are taking this opportunity to re-engineer these programs within budgetary constraints. We are working closely with major Federal users of our data and also seeking comments on the proposed program from interested private data users. We have established a NAICS Interagency Working Group composed of the Bureau of Economic Analysis, Bureau of Labor Statistics, Federal Reserve Board, and the Council of Economic Advisors to assist us in the redesign of the program. Representatives from these agencies were given a "fresh slate" to make recommendations on the data that should be collected in the current economic statistics program. From that "fresh slate" approach, new and different surveys and data items are being designed. Below is a discussion of the issues for those programs whose content may be significantly affected by the implementation of NAICS.

M3, Manufacturers' Shipments, Inventories, and Orders

As outlined earlier, NAICS completely restructures the manufacturing sector, recognizing 79 new industries and revising some 170 other SIC industries. The M3 currently collects and publishes information on groupings of SIC industries, some 80 categories. Of the 80 SIC-based categories, almost 80 percent are changed because of NAICS. What should the new NAICS-based groupings be and how many should be collected and published? Preliminary plans include increased emphasis and detail for computers and high-tech industries. A complete plan for the redesigned survey will be available for comment by data users within the next few months.

Current Services Program

Retail Sales/Wholesale Trade - With the redefinition of the distinction between retail and wholesale trade, these two monthly economic indicators will change. Annual NAICS-based data for retail/wholesale sales will first be collected in the 1999 annual surveys. Information will be requested for both 1998 and 1999 data years to ensure a comparable series from 1997 (Economic Census) forward.

The Advance Monthly Retail Sales report will continue to be published, but will not be comparable to past series. Even though restaurants are no longer part of retail trade in NAICS, data for restaurants will continue to be collected monthly, but will not be published as part of retail sales. In addition, many businesses formerly classified in wholesale will now be retailers. For example, as a result of the 1996 classification survey conducted by Census to assign NAICS codes to establishments that would be moving between sectors we found that:

Our preliminary census review has found even greater movement from wholesale to retail so that both of these monthly surveys will change considerably even though the individual kind of business titles remain about the same. Two important new categories that will be available in the full monthly and the annual retail sales report are sales of computer and software stores and warehouse clubs and superstores. Although not part of retail sales, monthly and annual data also will be available for full-service versus limited-service restaurants. The categories currently included in the wholesale trade report will not change.

Annual Services Programs

The most significant changes to current programs will be in the current services programs. Services now constitutes about 65 percent (including wholesale and retail trade) of Gross Domestic Product and measuring the economic activity of these important industries is critical. NAICS recognizes nine new services sectors and 250 new service industries, including a new information sector. Difficult decisions must be made on which of these industries will be surveyed and at what level of detail (NAICS 6-digit or some higher aggregation) the data will be collected.

At the top of the list for inclusion in a redesigned services program is a new annual information survey. Publishing, formerly included in both the M3 and the Annual Survey of Manufactures; broadcasting and telecommunications, formerly a separate survey; motion picture and sound recording and data processing services, on-line information services, and libraries, formerly part of the Services Annual Survey, all will be included in this new survey.

Other sectors to be covered as part of the program are Professional, Technical, and Scientific Services; Administrative and Support, Waste Management and Remediation Services; Rental and Leasing; Health Care and Social Assistance; and Arts, Entertainment and Recreation. Parts of additional sectors such as Educational Services; Transportation and Warehousing; and Other Services also may be covered. Without additional funding, finance, insurance, and real estate will not be covered.

Final decisions have not been made on the level of detail to collect (i.e., NAICS 4-, 5-, or 6-digit level). We also are considering conducting some of these surveys every other year and using administrative records in lieu of direct reporting for small businesses. We have developed a set of objective criteria (statistical importance, critical nature of the information to key statistical measurement programs, uniqueness of information, time-series comparability, and statistical measurement problems) that will be used to make decisions on what can and cannot be included based on funding levels.

Survey of Industrial Research and Development

This survey is funded by the National Science Foundation (NSF). Staff responsible for this survey are working with the NSF on alternative survey reporting of R&D expenditures by end use industries (NAICS basis). If alternative reporting is feasible, the survey will be completely redesigned and a complete break in time series will occur.

Time Series/ Seasonal Adjustment(1)

One of the most critical issues facing the Census Bureau as it implements NAICS is the development of a time series needed to seasonally adjust the principal economic indicator surveys. Our goal is to develop a time series for the M3, retail sales and inventories, and wholesale trade sales and inventories back to 1992. We are not certain if this will be possible for every data element currently published and will not know this until 1997 Economic Census results are tabulated and applied to the monthly survey data. We will make the series that we develop available to the public for their use. However, we reserve the option of not producing back NAICS time series or not seasonally adjusting the NAICS series if, in our opinion, the back data are not of sufficient quality to be released or to support adjustment. In that case, we may revise and adjust at a more aggregate level.

We are still researching the best approach to use to create the time series. For the M3, staff are planning to first derive the annual benchmark estimates and then derive the actual monthly series. There are two approaches for each operation: micro and macro. For creating the benchmark estimates, the micro approach involves using reported 1992 Census product data and the 1997 Census product data when it is available to recode establishments to a NAICS basis (we estimate that about 90 percent of the establishments can be recoded to the 6-digit level). However, for M3 purposes, we need only to be able to code to the 80 or so new NAICS M3 categories. The same operation would then be done for the ASM years of 1992-1996. This is much more difficult and time intensive as each component of the ASM estimator needs to be reconstructed. The macro approach, on the other hand, determines which SIC-based M3 category is the closest match to the new NAICS category and then adjusts the original SIC benchmark to reflect the new NAICS-based M3 category.

Once the benchmark is created, the detailed time series must be developed. The micro approach will allow us to determine how each company's 1992 activity is distributed across the new categories. This percentage distribution is then applied to the historical reported M3 monthly data to derive the monthly estimates. The macro approach splits each new M3 category into its earlier SIC components. A derived monthly series can then be created by aggregating the appropriate SIC monthly data in correct proportions. The creation of the time series relies on assumptions based on SIC-based reporting that could be much different than NAICS-based reporting, causing revisions as we collect and produce more NAICS data in the future.

For the retail/wholesale monthlies, we plan to retabulate the microdata of those series that are not a direct conversion. If an SIC reporting unit is split into two or more NAICS categories, we will split the unit based on its 1997 Economic Census reporting pattern. We will account for unmatched cases by using the same percentage split as that found for the matched cases. All births will be coded on both a NAICS and SIC basis for 1997 onward and we feel that our NAICS estimates for these years will be fairly reliable. We will be looking at each series separately to determine its reliability for years prior to 1997.

The QFR plans to convert to NAICS beginning with the fourth quarter of data year 2001. Plans are to provide only four previous quarters of estimates on a NAICS basis. Only net sales and net income after tax for nondurable and durable manufacturing are seasonally adjusted for this survey. SIC-based historical data will be used as input for seasonal adjustment on a NAICS basis if the seasonal impact of industries changed significantly by NAICS is small. Alternatives will be developed for seasonally adjusting the data if the impact is large.

No time series data will be developed for annual surveys, except for the benchmarks needed for the M3, retail sales, and wholesale trade. Rather, data users will need to use the 1997 Economic Census bridge tables to link the data from 1997 on to data produced on an SIC basis prior to 1997.

Outreach Activities

The Census Bureau is undertaking a large-scale outreach program to both data users and data providers to acquaint them with NAICS and its effect on the statistical programs of the Census Bureau. Two working groups are responsible for developing and implementing the outreach program.

Data Users

Time series, new data products, new industry titles, and new industry codes are each difficult issues for data users to contend with. With the implementation of NAICS, all must be assimilated at once. We hope to make the transition a bit easier for users of census data by providing users with as much information as possible. Of course, one of the most important tools for use in the transition to NAICS was the publication of the NAICS United States manual in July. Now users of SIC-based data have a complete description of the NAICS industries and a listing of the activities included in each. In addition, the final correspondence tables between NAICS and the SIC are available to help users compare the two systems.

The Census Bureau has established a comprehensive NAICS web site that provides an exhaustive source of information about NAICS from its early beginnings to the final correspondence tables. The site also provides the user an opportunity to ask Dr. NAICS questions about NAICS and what it means, including their new NAICS code.

The NAICS Outreach Group also has developed an informative NAICS brochure that provides highlights of NAICS. The statistical agencies are attending conferences and trade association meetings to speak about plans for NAICS implementation. Where possible the Bureau of Economic Analysis, Bureau of Labor Statistics (BLS), and Census Bureau attend as a group to discuss the issues surrounding NAICS as each agency implements the new system. Since there is a phased-in program across the agencies, not all series will be converted to a NAICS basis at the same time. For example, the Producer Price Index of the BLS will not convert to NAICS until 2004. Employment data from the BLS will not be available on a NAICS basis until 2002. A complete time schedule for all statistical agencies is shown in Attachment B. This staggered implementation will cause problems for data users as some series will be SIC-based and others NAICS-based and the data user must be cognizant of these future problems.

Other outreach activities include attendance at trade shows where an informational booth will be available; continued publication of articles about NAICS in trade magazines and the national press; and special mailings to data users informing them of proposed changes in surveys and soliciting their comments on these changes.

Data Providers

Our data providers are very special Census Bureau customers. Many tailor their recordkeeping to provide for responding to Census surveys. Others use the SIC for both internal recordkeeping and external customer classification. It is essential that we provide them with information and special tools as necessary to make the conversion to NAICS.

Over the past several years, we have worked with the business community responding to census surveys to organize reporting arrangements to ensure that the proper information is reported in economic surveys and to the extent possible limit reporting burden to the individual companies. With the implementation of NAICS, most of these reporting arrangements must be changed, and over the next several months we will begin working with these companies to set these reporting units in place. This will be a coordinated effort across the Economic Directorate of the Census Bureau and will include special mailing packages, telephone conferences, and individual company visits.

Birth/Administrative Record Coding

Plans for nonemployer NAICS coding was discussed earlier. However, for the current program, there is a second important issue related to administrative record coding that must be overcome. For the past several years, the Census Bureau has used the SIC code assigned by the Social Security Administration for new employer establishments (births). These new births are especially important to the current services program as there are about 750,000 new establishments in services each year. NAICS coding of these new establishments is essential for Census implementation of NAICS.

The Social Security Administration has agreed to continue industry coding of these births and will adopt NAICS for business registrations they receive effective January 1, 1999 and thereafter. Since services surveys add births on a quarterly basis and will need NAICS codes for 1998 before Social Security begins their coding operation, Census will continue its current birth coding program, adding the questions it needs to code births selected for the surveys on both an SIC and NAICS basis. By doing that, we will continue to publish information on an SIC basis in the current program for 1997 and 1998 and then will be able to re-publish the 1998 data on NAICS basis since both codes will be in our records.


To implement NAICS in the current programs, additional funding is needed. The business register must be converted to a NAICS basis, survey content issues must be settled, new samples must be drawn, and time series created for the economic indicator surveys. We must establish new reporting patterns for large companies and educate our data users about the effect NAICS will have on the data they use.

The President's FY 1999 budget has requested the funding needed to ensure timely, complete implementation of NAICS. We also have requested funding to expand our current program to include more information on services and construction industries, needed by BEA for the national accounts. Congressional action is expected this summer.

Current Programs Implementation Time Schedule

The Current Industrial Reports (CIR) are not affected by NAICS. The CIRs are product-based surveys and while the product codes will be converted to a NAICS basis, there will be no change in content because of NAICS nor will there be any disruption in time series. Likewise, the current construction surveys conducted and published by the Census Bureau will not change because of NAICS. These, too, are not industry-based surveys so will not change because of NAICS implementation.

Plans are to begin a phased-in implementation of NAICS in the Census Bureau's remaining current economic statistics programs. The first annual surveys to be converted to NAICS are the Annual Survey of Manufactures (ASM) and County Business Patterns (CBP) which will be published on a NAICS basis only for data year 1998. No SIC information will be published; data users can use the 1997 bridge tables for establishing the links between the 1998 ASM and CBP and data from prior years.

Other annual surveys will be converted to NAICS for data year 1999. This includes Annual Capital Expenditures, Survey of Industrial Research and Development (R & D), Survey of Plant Capacity Utilization, and the five current services surveys: Annual Retail Trade, Annual Wholesale Trade, Services Annual Survey, Annual Survey of Communications Services, and Transportation Annual Survey. The R & D survey and Survey of Plant Capacity Utilization will provide key data on a NAICS basis for 1997 data year forward when the 1999 information is published. The current services surveys will collect and publish information for data years 1998 and 1999, providing NAICS-based information to the data user from 1997 (Economic Census data) forward.

The industry-based economic indicator surveys, conducted on a monthly or quarterly basis, will be moved to a NAICS basis effective in 2001/2002. These include Manufacturers' Shipments, Inventories, and Orders (M3); Quarterly Financial Report (QFR); Retail Sales; Wholesale Trade; and Manufacturing and Trade Inventories and Sales.


NAICS represents the first restructuring of the economic classification system of the United States since the SIC was first developed in the 1930's. Increasingly, U.S. analysts were measuring the high-tech, services-oriented economy of the 1990's using tools developed a half-century earlier when manufacturing was the dominate force in the economy. While the new system means a more accurate accounting of the U.S. economy, the new system also means that data users must cope with time series losses and new data products. The statistical agencies will provide as many tools as possible to help with the transition and will continue to educate the public about NAICS, its benefits, and the changes coming.

NAICS will reshape our view of the U.S. economy. As Business Week said in its December 19, 1997 issue, "The U.S. is getting data for a new economy -- and it's about time." (2)
