Analysis
NAICS 3343 is the 2022 industry group for audio and video equipment manufacturing, part of 334 (Computer and Electronic Product Manufacturing).
It has only one more detailed code, 334310, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments grew 17% and employment rose 22%. 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 539 US establishments in this code in 2023, employing 10,977 people at an average annual payroll of $78,457 per employee (67th percentile of national industries). 50% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 5th of the 6 codes at this level within Computer and Electronic Product Manufacturing, with 4.8% of them.
