Why are certain businesses surveyed?
Certain businesses are selected at random from the Unemployment Insurance quarterly tax files by the U.S. Department of Labor. Any one business in the survey represents other businesses in the same county with the same approximate number of employees, running the same type of business. Whether a business is large or small, it is very important to be represented in the overall picture. Occupations with the wage ranges are critical for the accuracy of the data collected.
