Premium Business Patterns

Devonshire uses the latest County Business Patterns files at the County and ZIP Code levels to provide data on the number of establishments, number of employees, and number of establishments by employment-size class for all NAICS codes.  The data is provided annually by the Bureau of the Census.

Devonshire estimates non-disclosed information in the County Business Patterns file at the County and ZIP Code levels.  The national averages are used to estimate the non-disclosed data for all NAICS.  The final data for all NAICS are controlled at all levels of geography.

Premium Occupation Patterns

The Standard Occupation Classification Matrix obtained from the Census Bureau reports NAICS codes for over 600 occupations.  The information on each occupation is reported as a percent of the occupation within a NAICS code as compared to the total U.S. employment in the NAICS code.  The file includes information on wage/salary workers, self-employed and unpaid family workers for all occupations.  Additionally, the file also contains projections to total employed, salaried, self-employed and unpaid family workers for the year 2012.

In order to create county-level estimates, Devonshire first applied Premium Business Patterns employment figures within a NAICS code to the Census Bureau's national percent of employment in an occupation within the NAICS code.  Second, Devonshire adjusts 2012 year projection data on occupations to create a current-year estimate.  This estimate is then applied to update the county-level estimates.

A similar procedure is followed to create ZIP Code-level estimates.
