Analysis
NAICS 81393 is the 2022 NAICS industry for labor unions and similar labor organizations, part of 8139 (Business, Professional, Labor, Political, and Similar Organizations).
It has only one more detailed code, 813930, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 12,813 US establishments in this code in 2023, employing 136,752 people at an average annual payroll of $50,773 per employee (18th percentile of national industries). 45% of the establishments have fewer than five employees, which is close to the national mix.
Between 2018 and 2023 the number of establishments fell 6% and employment fell 6%. 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 3rd of the 5 codes at this level within Business, Professional, Labor, Political, and Similar Organizations, with 23.5% of them.
