Analysis
NAICS 5174 is the 2022 industry group for satellite telecommunications, part of 517 (Telecommunications).
It has only one more detailed code, 517410, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 429 US establishments in this code in 2023, employing 9,919 people at an average annual payroll of $152,953 per employee (97th percentile of national industries). 61% of the establishments have fewer than five employees, which marks it as a small-business industry.
Between 2018 and 2023 the number of establishments grew 5% and employment rose 20%. 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.
