Analysis
NAICS 31123 is the 2022 NAICS industry for breakfast cereal manufacturing, part of 3112 (Grain and Oilseed Milling).
It has only one more detailed code, 311230, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 94 US establishments in this code in 2023, employing 13,258 people at an average annual payroll of $75,469 per employee (63rd percentile of national industries). 29% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 3rd of the 3 codes at this level within Grain and Oilseed Milling, with 10.1% of them.
Between 2018 and 2023 the number of establishments grew 12% and employment rose 5%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
