However, construction work performed as the primary activity of a separate establishment of an enterprise for the enterprise's own account is included in this division. The installation of prefabricated building equipment and materials by general and special trade contractors is classified in this division.
Similar installation work performed as a service incidental to sale by employees of an establishment manufacturing or selling prefabricated equipment and materials is classified according to the primary activity in the Manufacturing or Trade Divisions.
Establishments primarily engaged in the distribution and construction or installation of equipment often present classification problems. Since value added is not available for distinguishing the relative importance of sales versus installation or construction activities, payroll or employment may be used as measures yielding approximately the same results.
On this basis, separate establishments primarily engaged in the sale and installation of the following illustrative types of structures or integral parts of structures generally site assembled, are classified in construction rather than in trade:. Steel work on bridges or buildings; b. Elevators and escalators; c. Sprinkler systems; d. Central air-conditioning and heating equipment; e. Communications equipment; and f. Insulation materials. On the other hand, establishments primarily engaged in the sale and installation of the following illustrative types of preassembled equipment are classified in trade rather than in construction:.
Since then, the system has been largely replace by the North American Industry Classification System, however, some public and private institutions continue to use SIC codes classify businesses. Each SIC code consists of 4 numbers.
When working with the Standard Industrial Classification it is useful to store the numbers as text, to preserve the leading zeros, and make sure that the length of each code is exactly 4 characters. For example, you should store the code representing Agricultural Services as and not SIC codes are divided into 10 main division and one "Nonclassifiable" division of codes:.
The discussion around creating the standardized classification of economic activities began in at an Interdepartmental Conference on Industrial Classification. At that time, there were a number of different, inconsistent classification systems used by individual government agencies. As a result, it was impossible to accurately compare statistics from one agency to another. For example, if one agency reported on production output, and other on employment, there was no way to link that data.
Data for the aggregates of all industrial activity are assigned an industry code of 0Z. Indicates the area for which the data were reported. The database uses a five-character code for each area. This database of Quarterly Census of Employment and Wages information reports five datatypes: All employees , number of establishments , total wages , average weekly wage , and average annual pay.
Indicates the establishment size for which the data were reported. Currently, only data from all establishment sizes combined are reported in this database. Reported number of establishments represents the number of establishments whose activities were reported to the Unemployment Insurance system for the quarter.
An establishment is an economic unit, such as a farm, mine, factory, or store, which produces goods or provides services. It is typically at a single physical location and engaged in one, or predominantly one, type of economic activity for which a single industrial classification may be applied.
Reported annual average number of establishments is an average of the corresponding quarterly number of establishment levels. Reported quarterly total wages are the wages paid by Unemployment Insurance covered employers during the calendar quarter, regardless of when the services were performed.
Reported total annual wages are the sum of the total wages reported for the corresponding quarters.
