The Occupational Classification System manual was created for Bureau of Labor Statistics (BLS) field economists to help ensure correct occupational matches when collecting compensation data. The public can benefit from this manual by looking up job descriptions for occupations found in the NCS bulletins, and by knowing how the field economist classifies the thousands of occupations into BLS Major Occupation Groups (MOGs), e.g., Professional Occupations; sub-MOGs, e.g., Engineers, Architects, and Surveyors; or specific occupations, e.g., Aerospace Engineers.
Following the list of Major Occupational Groups below is a link to the Census Occupation Index. This Index presents alphabetical access to approximately 21,000 industry and 30,000 occupation titles. The Index provides a rapid way to identify a specific occupation, the MOG, and related Census code, e.g., Accountant, B023.
