Economic Censuses and Related Publications

What are the economic censuses?

The economic censuses are comprehensive canvasses of industrial and business activities.  They are conducted every 5 years, in years ending in 2 and 7. The economic censuses include

Most economic censuses provide detailed data in three categories

Key statistics are tabulated for all industries

History

The first economic census of the United States was conducted as part of the 1810 decennial census.  

How Statistics are Collected

1997 economic census forms will be mailed to over 5 million companies.  These companies are required by law to respond, but information from the questionnaire can only be used for the census and cannot be used for the purposes of taxation, investigation or regulation.  As with other censuses, no data is published that could reveal the identity of a specific individual or firm.

How Statistics are Reported

Establishments

Statistics for the economic censuses are collected and summarized in terms of the "establishment."  An establishment is defined as a business or industrial unit at a single geographic location which produces or distributes goods or performs services.  For instance, the sales of sporting goods stores, the production of fertilizer plants, or employment in electronic repair shops.  

When more than one economic activity is conducted at a single location, each activity is treated as a separate establishment if separate records are available and if the size of the individual activities is significant.  

Industrial Classification

The 1997 economic censuses will classify statistics primarily using the 1997 North American Industry Classification System (NAICS) and to a lesser extent the 1987 Standard Industrial Classification (SIC) system. Both NAICS and SIC categorize establishments by the principal activity in which they are engaged.

A limited amount of data from the 1997 census will be published according to the old Standard Industrial Classification (SIC) system: certain national preliminary totals in the first publications (early 1999), a detailed "bridge table" showing the relationships between NAICS and SIC categories a year later, and state level statistics based on SIC, also in 2000, but after publication of geographic area data by NAICS.

For more information, see How NAICS Will Affect Data Users.

NAICS, the North American Industry Classification System

The North American Industry Classification System was developed in cooperation with Canada and Mexico.  It classifies North America's economic activities at 2-, 3-, 4- and 5-digit levels of detail.  The U.S. version of NAICS further defines some industries to a sixth digit.    

SIC, the Standard Industrial Classification System

In previous economic censuses, except for portions of the census of transportation, data have been tabulated on the basis of the Standard Industrial Classification (SIC) system.  The SIC divided economic activities into broad industrial divisions, such as manufacturing and retail trade, 2-digit major groups, 3-digit industry subgroups, and 4-digit detailed industries. In some cases, more detailed classification was devised so that additional industries, kinds of business or specific products can be identified within SIC categories.  

The 1987 SIC Manual, which is the one currently in use, is on Quick Reference,  PREX 2.6/2:In 27/987.  We also have earlier SIC manuals in the stacks at the same call number stem.. A searchable WWW version is available from the Occupational Safety and Health Administration.

Geography

In general the most detailed data are published at the national level. Most statistics are available for states, and many are shown for cities and other places, counties and defined statistical areas. Only recent and limited data are provided by  ZIP Codes.  Statistics for smaller areas are sometimes withheld to avoid disclosing information about individual firms.  

Statistics from the basic economic censuses for Puerto Rico, the Virgin Islands, Guam, and the Northern Mariana Islands are published as the Census of Outlying Areas.  These censuses have been taken in Puerto Rico since 1909, the Virgin Islands and Guam since 1958, and the Northern Mariana Islands since 1982.

Economic Surveys

Most censuses are updated by publications with data which are collected by surveys with samples which are reselected every five years.  Reports based on sample surveys generally include measurements of sampling variability. Many monthly and quarterly survey results are adjusted for seasonality.  

To the extent possible, concepts, definitions, and reporting units are consistent among the censuses, surveys and related programs.  Census results supply the sample frames, benchmark statistics, and list of establishments and firms for surveys taken more frequently.  Survey results can be reconciled with those from a census and vice-versa.  

When you move from census data to survey data, detail is lost.  The detail may be in terms of the number of variables used and almost always geographic detail.    

Publications which update the economic censuses are listed under the sections below on individual economic censuses.

How Statistics are Published

The Census Bureau plans to publish only highlights of the 1997 Economic Census in paper reports.  These will feature primarily national data and general statistics by state, and include illustration of some of the more detailed data, which will be available on CD-ROM and the Internet.

The Census Bureau has also said that with the 1997 Economic Census reports, the different sectors will no longer be treated as if they had a separate census, e.g., the Census of Manufactures, and all reports will be titled as the Economic Census.
