Analysis

NAICS 813920 is the 2022 national industry for professional organizations, part of 81392 (Professional Organizations). Census lists 25 example activities under it in the official index.

County Business Patterns counts 6,529 US establishments in this code in 2023, employing 86,514 people at an average annual payroll of $101,242 per employee (85th percentile of national industries). 62% of the establishments have fewer than five employees, which marks it as a small-business industry.

Between 2018 and 2023 the number of establishments fell 12% 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.

Its index entries, the activities Census uses to assign businesses to this code, include accountants' associations, architects' associations, bar associations and consultants' associations, among 25 in all.

For example, promoting the business interests of their members are classified in 813910 (Business Associations) instead.

Census lists 2 related activities that belong elsewhere, most often in 813910 and 541820. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
