Occupational Codes

Standard Occupational Classification

The 2000 Standard Occupational Classification (SOC) system is used by statistical agencies to classify workers into occupational categories for the purpose of collecting, calculating, or disseminating data. Workers are classified into one of more than 820 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 occupations requiring similar job duties, skills, education or experience.
