Analysis
NAICS 4811 is the 2022 industry group for scheduled air transportation, part of 481 (Air Transportation).
It has only one more detailed code, 48111, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 2,233 US establishments in this code in 2023, employing 501,126 people at an average annual payroll of $101,948 per employee (85th percentile of national industries). 33% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 2nd of the 2 codes at this level within Air Transportation, with 47.1% of them.
Between 2018 and 2023 the number of establishments grew 1% and employment rose 15%. 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.
