Economic Census 1997. All Other Heavy Construction. Construction Industry Series. 1997

摘要

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. The economic census furnishes an important part of the framework for such composite measures as the gross domestic product estimates, input/output measures, production and price indexes, and other statistical series that measure short-term changes in economic conditions. Specific uses of economic census data include the following: policymaking agencies of the Federal Government use the data to monitor economic activity and assess the effectiveness of policies; state and local governments use the data to assess business activities and tax bases within their jurisdictions and to develop programs to attract business; trade associations study trends in their own and competing industries, which allows them to keep their members informed of market changes; and individual businesses use the data to locate potential markets and to analyze their own production and sales performance relative to industry or area averages. Data from the 1997 Economic Census are published primarily on the basis of the North American Industry Classification System (NAICS).
