Analysis
NAICS 48819 is the 2022 NAICS industry for other support activities for air transportation, part of 4881 (Support Activities for Air Transportation).
It has only one more detailed code, 488190, which covers exactly the same activities; the definition, index entries and statistics are on that page.
By establishments it ranks 1st of the 2 codes at this level within Support Activities for Air Transportation, with 62.1% of them.
County Business Patterns counts 4,237 US establishments in this code in 2023, employing 103,177 people at an average annual payroll of $72,861 per employee (56th percentile of national industries). 52% of the establishments have fewer than five employees, which is close to the national mix.
Between 2018 and 2023 the number of establishments grew 8% and employment rose 18%. 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.
