81121

Analysis

NAICS 81121 is the 2022 NAICS industry for electronic and precision equipment repair and maintenance, part of 8112 (Electronic and Precision Equipment Repair and Maintenance).

It has only one more detailed code, 811210, which covers exactly the same activities; the definition, index entries and statistics are on that page.

Between 2018 and 2023 the number of establishments fell 12% and employment fell 12%. 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 10,917 US establishments in this code in 2023, employing 89,305 people at an average annual payroll of $68,726 per employee (50th percentile of national industries). 70% of the establishments have fewer than five employees, which marks it as a small-business industry.
