Economic Census 2002: Manufacturing, Industry Series. Power Boiler and Heat Exchanger Manufacturing

摘要

The economic census is the major source of facts about the structure and functioning of the nations 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.
