Analysis
NAICS 8133 is the 2022 industry group for social advocacy organizations, part of 813 (Religious, Grantmaking, Civic, Professional, and Similar Organizations).
It has only one more detailed code, 81331, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments grew 16% and employment rose 16%. 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 5th of the 5 codes at this level within Religious, Grantmaking, Civic, Professional, and Similar Organizations, with 6.9% of them.
County Business Patterns counts 21,255 US establishments in this code in 2023, employing 214,947 people at an average annual payroll of $66,154 per employee (45th percentile of national industries). 57% of the establishments have fewer than five employees, which is close to the national mix.
