The physical location of a certain economic activity, for example, a factory, mine, store, or office. Generally a single establishment produces a single good or provides a single service. An enterprise (a private firm, government, or non-profit organization) could consist of a single establishment or multiple establishments. A multi-establishment enterprise could have all its establishments in one industry (i.e., a chain), or could have various establishments in different industries (i.e., a conglomerate).


Estimate of Employment

The estimated employment for an occupation across all industries within the state. These estimates were obtained by summing employment in each wage interval across all industries. A further adjustment was made in order to match the estimated occupational employment within each industry and MSA to the universe employment (obtained from Unemployment Insurance tax files) in the industry and MSA.


Mean Wage

An average wage. An occupational mean wage estimate is calculated by summing the wages of all the employees in a given occupation and then dividing the total wages by the number of employees.


Median Wage

A boundary. An occupational median wage estimate is the boundary between the highest paid 50% and the lowest paid 50% of workers in that occupation. Half of the workers in a given occupation earn more than the median wage and half the workers earn less than the median wage.



The middle fifty percent of the wage observations in a wage distribution. Another way to interpret a mid-range is to observe that 25 percent of workers in the occupation are paid less than the lower boundary of the mid-range, and 25 percent of workers are paid more than the upper boundary. The mid-range is the range between the twenty-fifth and seventy-fifth percentiles.



A set of activities or tasks employees are paid to perform. Employees that perform essentially the same tasks are in the same occupation, whether or not they are in the same industry. Some occupations are concentrated in a few particular industries, other occupations are found in the majority of industries.


Standard Occupational Classification (SOC) System

This system will be used by all federal statistical agencies to classify workers into occupational categories for the purpose of collecting, calculating, or disseminating data. All workers are classified into one of 821 occupations according to their occupational definition. To facilitate classification, occupations are combined to form 23 major groups, 96 minor groups, and 449 broad occupations. Each broad occupation includes detailed occupation(s) requiring similar job duties, skills, education, or experience.


Wages and Salaries

Hourly straight-time wage rate or, for workers not paid on an hourly basis, straight-time earnings divided by the corresponding hours. Straight-time wage and salary rates are total earnings before payroll deductions, excluding premium pay for overtime and for work on weekends and holidays, shift differentials, and non-production bonuses such as lump-sum payments provided in lieu of wage increases.
