Analysis
NAICS 3332 is the 2022 industry group for industrial machinery manufacturing, part of 333 (Machinery Manufacturing).
It has only one more detailed code, 33324, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 2,836 US establishments in this code in 2023, employing 111,497 people at an average annual payroll of $98,245 per employee (83rd percentile of national industries). 31% of the establishments have fewer than five employees, which is close to the national mix.
Between 2018 and 2023 the number of establishments fell 8% and employment rose 2%. 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.
By establishments it ranks 3rd of the 7 codes at this level within Machinery Manufacturing, with 13.1% of them.
