Analysis
NAICS 48851 is the 2022 NAICS industry for freight transportation arrangement, part of 4885 (Freight Transportation Arrangement).
It has only one more detailed code, 488510, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 21,873 US establishments in this code in 2023, employing 324,765 people at an average annual payroll of $76,333 per employee (63rd percentile of national industries). 55% of the establishments have fewer than five employees, which is close to the national mix.
Between 2018 and 2023 the number of establishments grew 3% and employment rose 19%. 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.
