Analysis
NAICS 11132 is the 2022 NAICS industry for citrus (except orange) groves, part of 1113 (Fruit and Tree Nut Farming).
It has only one more detailed code, 111320, 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.
