Analysis
NAICS 22121 is the 2022 NAICS industry for natural gas distribution, part of 2212 (Natural Gas Distribution).
It has only one more detailed code, 221210, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 2,434 US establishments in this code in 2023, employing 95,538 people at an average annual payroll of $121,200 per employee (91st percentile of national industries). 34% of the establishments have fewer than five employees, which is close to the national mix.
Between 2018 and 2023 the number of establishments fell 3% and employment rose 5%. 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.
