Analysis
NAICS 56199 is the 2022 NAICS industry for all other support services, part of 5619 (Other Support Services).
It has only one more detailed code, 561990, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 12,567 US establishments in this code in 2023, employing 173,815 people at an average annual payroll of $56,882 per employee (27th percentile of national industries). 58% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 1st of the 3 codes at this level within Other Support Services, with 60.4% of them.
Between 2018 and 2023 the number of establishments fell 3% and employment rose 9%. 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.
