Analysis
NAICS 3336 is the 2022 industry group for engine, turbine, and power transmission equipment manufacturing, part of 333 (Machinery Manufacturing).
It has only one more detailed code, 33361, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 899 US establishments in this code in 2023, employing 96,251 people at an average annual payroll of $80,745 per employee (69th percentile of national industries). 21% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 7th of the 7 codes at this level within Machinery Manufacturing, with 4.1% of them.
Between 2018 and 2023 the number of establishments fell 9% and employment fell 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.
