Analysis
NAICS 2372 is the 2022 industry group for land subdivision, part of 237 (Heavy and Civil Engineering Construction).
It has only one more detailed code, 237210, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 4,441 US establishments in this code in 2023, employing 24,810 people at an average annual payroll of $90,096 per employee (78th percentile of national industries). 75% of the establishments have fewer than five employees, which marks it as a small-business industry.
By establishments it ranks 4th of the 4 codes at this level within Heavy and Civil Engineering Construction, with 11.5% of them.
Between 2018 and 2023 the number of establishments fell 11% and employment rose 13%. 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.
