Analysis
NAICS 3353 is the 2022 industry group for electrical equipment manufacturing, part of 335 (Electrical Equipment, Appliance, and Component Manufacturing).
It has only one more detailed code, 33531, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments fell 13% and employment rose 7%. 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.
County Business Patterns counts 1,793 US establishments in this code in 2023, employing 125,655 people at an average annual payroll of $75,704 per employee (63rd percentile of national industries). 27% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 2nd of the 4 codes at this level within Electrical Equipment, Appliance, and Component Manufacturing, with 33.2% of them.
