Analysis
NAICS 54133 is the 2022 NAICS industry for engineering services, part of 5413 (Architectural, Engineering, and Related Services).
It has only one more detailed code, 541330, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 63,233 US establishments in this code in 2023, employing 1,260,577 people at an average annual payroll of $109,949 per employee (88th percentile of national industries). 53% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 1st of the 8 codes at this level within Architectural, Engineering, and Related Services, with 53.9% of them.
Between 2018 and 2023 the number of establishments grew 2% and employment rose 14%. 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.
