Analysis
NAICS 33995 is the 2022 NAICS industry for sign manufacturing, part of 3399 (Other Miscellaneous Manufacturing).
It has only one more detailed code, 339950, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 5,895 US establishments in this code in 2023, employing 75,898 people at an average annual payroll of $58,525 per employee (30th percentile of national industries). 51% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 1st of the 6 codes at this level within Other Miscellaneous Manufacturing, with 39.8% of them.
Between 2018 and 2023 the number of establishments grew 1% and employment fell 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.
