56133

Analysis

NAICS 56133 is the 2022 NAICS industry for professional employer organizations, part of 5613 (Employment Services).

It has only one more detailed code, 561330, 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 26%. 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 3 codes at this level within Employment Services, with 7.7% of them.

County Business Patterns counts 4,343 US establishments in this code in 2023, employing 3,777,023 people at an average annual payroll of $72,164 per employee (55th percentile of national industries). 26% of the establishments have fewer than five employees, which is close to the national mix.
