The manufacturing sector comprises establishments engaged in the mechanical, physical, or chemical transformation of materials, substances, or components into new products. The 2002 Economic Census classifies businesses according to the North American Industry Classification System (NAICS), 2002.
Value of shipments covers the received or receivable net selling values, f.o.b. plant (exclusive of freight and taxes), of all products shipped, both primary and secondary, as well as all miscellaneous receipts, such as receipts for contract work performed for others, installation and repair, sales of scrap, and sales of products bought and resold without further processing. Included are all items made by or for the establishments from materials owned by it, whether sold, transferred to other plants of the same company, or shipped on consignment. The net selling value of products made in one plant on a contract basis from materials owned by another was reported by the plant providing the materials.
Scope and Methodology:
The 2002 Economic Census measured activity during calendar year 2002. Large- and medium-size firms, including all firms known to operate more than one establishment, and a sample of small employers were sent questionnaires to be completed and returned to the Census Bureau by mail. Most very small firms were not sent a form, and data from existing administrative records of other Federal agencies were used instead.
These data include only establishments with paid employees.
