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. Title 13 of the United States Code (Sections 131, 191, and 224) directs the Census Bureau to take the economic census every 5 years, covering years ending in "2" and "7." 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: (1) Policymaking agencies of the federal government use the data to monitor economic activity and to assess the effectiveness of policies; (2) State and local governments use the data to assess business activities and tax bases within their jurisdictions and to develop programs to attract business; (3) Trade associations study trends in their own and competing industries, which allows them to keep their members informed of market changes; and (4) Individual businesses use the data to locate potential markets and to analyze their own production and sales performance relative to industry or area averages. The census is conducted on an establishment basis. A company operating at more than one location is required to file a separate report for each store, factory, shop, or other location. Each establishment is assigned a separate industry classification based on its primary activity and not that of its parent company. The Educational Services sector (sector 61) comprises establishments that provide instruction and training in a wide variety of subjects. This instruction and training is provided by specialized establishments, such as schools, colleges, universities, and training centers. Educational services are usually delivered by teachers or instructors that explain, tell, demonstrate, supervise, and direct learning. Instruction is imparted in diverse settings, such as educational institutions, the workplace, or the home through correspondence, television, or other means. Data for this sector are shown for establishments of firms subject to federal income tax, and separately, of firms that are exempt from federal income tax under provisions of the Internal Revenue Code.
