Analysis
NAICS 56151 is the 2022 NAICS industry for travel agencies, part of 5615 (Travel Arrangement and Reservation Services).
It has only one more detailed code, 561510, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 9,308 US establishments in this code in 2023, employing 82,899 people at an average annual payroll of $97,789 per employee (83rd percentile of national industries). 79% of the establishments have fewer than five employees, which marks it as a small-business industry.
Between 2018 and 2023 the number of establishments fell 18% and employment fell 16%. 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.
By establishments it ranks 1st of the 3 codes at this level within Travel Arrangement and Reservation Services, with 59.3% of them.
