Analysis
NAICS 3333 is the 2022 industry group for commercial and service industry machinery manufacturing, part of 333 (Machinery Manufacturing).
It has only one more detailed code, 333310, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 1,731 US establishments in this code in 2023, employing 80,504 people at an average annual payroll of $82,553 per employee (71st percentile of national industries). 32% 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 13%. 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 5th of the 7 codes at this level within Machinery Manufacturing, with 8% of them.
