Analysis
NAICS 23712 is the 2022 NAICS industry for oil and gas pipeline and related structures construction, part of 2371 (Utility System Construction).
It has only one more detailed code, 237120, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 2,156 US establishments in this code in 2023, employing 167,820 people at an average annual payroll of $88,525 per employee (76th percentile of national industries). 29% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 3rd of the 3 codes at this level within Utility System Construction, with 10.7% of them.
Between 2018 and 2023 the number of establishments fell 3% and employment fell 26%. 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.
