Industries in the Pipeline Transportation subsector use transmission pipelines to transport products, such as crude oil, natural gas, refined petroleum products, and slurry. Industries are identified based on the products transported (i.e., pipeline transportation of crude oil, natural gas, refined petroleum products, and other products). The Pipeline Transportation of Natural Gas industry includes the storage of natural gas because the storage is usually done by the pipeline establishment and because a pipeline is inherently a network in which all the nodes are interdependent. 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. 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. |
