Analysis
NAICS 238110 is the 2022 national industry for poured concrete foundation and structure contractors, part of 23811 (Poured Concrete Foundation and Structure Contractors). Census lists 15 example activities under it in the official index.
Between 2018 and 2023 the number of establishments grew 12% and employment rose 11%. 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.
County Business Patterns counts 23,350 US establishments in this code in 2023, employing 272,692 people at an average annual payroll of $70,546 per employee (53rd percentile of national industries). 59% of the establishments have fewer than five employees, which is close to the national mix.
Its index entries, the activities Census uses to assign businesses to this code, include chimney, concrete, construction, concrete finishing, concrete floor surfacing and concrete pouring, among 15 in all.
Census lists 4 related activities that belong elsewhere, most often in 237310, 238390, 238990 and 327320. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
For example, constructing or paving streets, highways, and public sidewalks are classified in 237310 (Highway, Street, and Bridge Construction) instead.
