Analysis
NAICS 11239 is the 2022 NAICS industry for other poultry production, part of 1123 (Poultry and Egg Production).
It has only one more detailed code, 112390, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns does not cover crop and animal production, so there is no establishment count for it; farms are counted by the Census of Agriculture instead.
