Analysis
NAICS 54136 is the 2022 NAICS industry for geophysical surveying and mapping services, part of 5413 (Architectural, Engineering, and Related Services).
It has only one more detailed code, 541360, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 993 US establishments in this code in 2023, employing 7,007 people at an average annual payroll of $109,086 per employee (88th percentile of national industries). 78% of the establishments have fewer than five employees, which marks it as a small-business industry.
By establishments it ranks 8th of the 8 codes at this level within Architectural, Engineering, and Related Services, with 0.8% of them.
Between 2018 and 2023 the number of establishments grew 1% and employment fell 5%. 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.
