Analysis
NAICS 7213 is the 2022 industry group for rooming and boarding houses, dormitories, and workers' camps, part of 721 (Accommodation).
It has only one more detailed code, 721310, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 1,589 US establishments in this code in 2023, employing 7,503 people at an average annual payroll of $33,178 per employee (6th percentile of national industries). 73% 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 17% and employment fell 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.
By establishments it ranks 3rd of the 3 codes at this level within Accommodation, with 2.3% of them.
