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.
