Analysis
NAICS 92614 is the 2022 NAICS industry for regulation of agricultural marketing and commodities, part of 9261 (Administration of Economic Programs).
It has only one more detailed code, 926140, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns excludes public administration, so there is no establishment count for it.
