Explanation of Terms


Establishment - A single physical location where business is conducted or where services or industrial operations are performed.

Employment - Paid employment consists of full and part-time employees, including salaried officers and executives of corporations, who were on the payroll in the pay period including March 12. Included are employees on sick leave, and vacations; not included are proprietors and partners of unincorporated businesses.

Annual Payroll - Total annual payroll includes all forms of compensation, such as salaries, wages, commissions, bonuses, vacation allowances, sick-leave pay, and the value of payments in kind (e.g., free meals and lodgings) paid during the year to all employees.

Enterprise -. An enterprise is a business organization consisting of one or more domestic establishments that were specified under common ownership or control. The "enterprise" and the "establishment" are the same for single-establishment companies. Each multi establishment company forms one enterprise - the enterprise employment and annual payroll are summed from the associated establishments.

Firm - A firm is a business organization consisting of one or more domestic establishments in the same state and industry division that were specified under common ownership or control. The "firm" and the "establishment" are the same for single-establishment firms. For each multi establishment firm, establishments in the same industry division within a state are counted as one firm - the firm employment and annual payroll are summed from the associated establishments.

Establishment Births - "Births" are new establishments that opened for business during the year 1991 which were not in existence in 1989.

Establishment Deaths - "Deaths" are establishments that closed business during the year 1991 which were in existence in 1989.

Establishment Contractions - "Contractions" are establishments that decreased in employment size during the time period 1989 - 1991.

Metropolitan Statistical Area (MSA) - An MSA is an integrated economic and social unit with a large population nucleus. Each MSA consists of one or more counties or statistically equivalent areas meeting published standards of population and metropolitan character; in the six New England States (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont), cities and towns (rather than counties) are used as the component geographic units.

Enterprise Size - Enterprise size designations are determined by paid employment in the mid-March pay period. The size group "0-4" includes enterprises that did not report any paid employees in the mid-March pay period but paid employees at some time during the year.

Note: The Company Organization Survey (COS) is the Census Bureau's main tool for identifying changes in multi-unit enterprise (an enterprise that own more than one establishment) structure in non-census years. Unfortunately, this survey samples only a portion of the known multi-unit enterprises each year. As a result, some inter-censal multi-unit births exist as single establishment enterprises on the Census Bureau's register until the enterprise is selected for the COS or until the next quinquennial census. Similar timing problems exist in identifying deaths, acquisitions, and divestitures of multi-unit establishments.
