Records Information
One row represents one official node in the finalized 2022 NAICS United States hierarchy. Codes remain text so combined sectors such as 31-33, 44-45, and 48-49 are preserved exactly. Every non-sector row has one immediate parent and a complete chain to its sector. Proposed 2027 revisions are excluded.
