How many major groups does the SOC classify workers into?

• A. 50
• B. 23
• C. 75
• D. 10

Answer: (B)

The SOC uses a hierarchical framework to organize occupations, with the top level consisting of 23 major groups. This 23-group structure groups broad families of work that share similar duties and skill needs, making it easier to analyze labor market data, compare job requirements, and standardize job descriptions across industries. Below these major groups are narrower levels—broad occupations, minor groups, and detailed occupations—that add specificity as you move down the hierarchy. So the correct count is 23 major groups.
