Analysis
NAICS 33429 is the 2022 NAICS industry for other communications equipment manufacturing, part of 3342 (Communications Equipment Manufacturing).
It has only one more detailed code, 334290, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 332 US establishments in this code in 2023, employing 12,455 people at an average annual payroll of $85,457 per employee (74th percentile of national industries). 37% of the establishments have fewer than five employees, which is close to the national mix.
Between 2018 and 2023 the number of establishments grew 2% 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.
By establishments it ranks 2nd of the 3 codes at this level within Communications Equipment Manufacturing, with 29.2% of them.
