*Establishment

An establishment is a single physical location at which business is conducted and/or services are provided. It is notnecessarily identical with a company or enterprise, which may consist of one establishment or more. Economic censusfigures represent a summary of reports for individual establishments rather than companies. For cases where a census reportwas received, separate information was obtained for each location where business was conducted. When administrativerecords of other Federal agencies were used instead of a census report, no information was available on the number oflocations operated. Each economic census establishment was tabulated according to the physical location at which thebusiness was conducted. The count of establishments represents those in business at any time during 1997.

When two activities or more were carried on at a single location under a single ownership, all activities generally weregrouped together as a single establishment. The entire establishment was classified on the basis of its major activity and alldata for it were included in that classification. However, when distinct and separate economic activities (for which differentindustry classification codes were appropriate) were conducted at a single location under a single ownership, separateestablishment reports for each of the different activities were obtained in the census.
