Analysis

NAICS 238150 is the 2022 national industry for glass and glazing contractors, part of 23815 (Glass and Glazing Contractors). Census lists 11 example activities under it in the official index.

Between 2018 and 2023 the number of establishments grew 15% and employment rose 7%. 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 6,945 US establishments in this code in 2023, employing 68,694 people at an average annual payroll of $69,666 per employee (52nd percentile of national industries). 52% 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 curtain wall, glass, installation, decorative glass and mirror installation, glass cladding (i.e., curtain wall), installation and glass coating and tinting (except automotive) contractors, among 11 in all.

For example, installing prefabricated window and door units are classified in 238350 (Finish Carpentry Contractors) instead.
