Analysis
NAICS 6111 is the 2022 industry group for elementary and secondary schools, part of 611 (Educational Services).
It has only one more detailed code, 611110, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 23,201 US establishments in this code in 2023, employing 1,176,824 people at an average annual payroll of $48,283 per employee (15th percentile of national industries). 15% of the establishments have fewer than five employees, which points to larger operations.
Between 2018 and 2023 the number of establishments grew 5% and employment rose 10%. 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 2nd of the 7 codes at this level within Educational Services, with 19.7% of them.
