Which SSIC code would denote a secondary subject?

Which SSIC code would denote a secondary subject?

• A. 5200
• B. 5210
• C. 5220
• D. 5230

Answer: (B)

SSIC codes are hierarchical: the first digits define a broad subject area, and the trailing digits specify the exact topic within that area. Within the 52xx block, ending digits like 10 are used to designate a secondary subject, distinguishing it from other topics in the same broad category. The other endings (00, 20, 30, etc.) point to different primary subtopics rather than a secondary subject. So 5210 is the code that denotes a secondary subject, making it the best choice.
