Records Information
One primary record represents one official node in the finalized 2018 SOC hierarchy. Codes remain text in canonical XX-XXXX form. Every non-major node has one immediate parent and a complete chain to its major group. Official direct-match titles are stored in a deterministic multivalue field and in a normalized SQLite child table. Proposed 2028 revisions and OEWS wage or employment estimates are excluded.
Designed for business research, directory applications, mapping, and market analysis. Review permitted uses.
