Analysis
NAICS 21112 is the 2022 NAICS industry for crude petroleum extraction, part of 2111 (Oil and Gas Extraction).
It has only one more detailed code, 211120, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments fell 25% 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.
County Business Patterns counts 3,863 US establishments in this code in 2023, employing 63,367 people at an average annual payroll of $200,722 per employee (100th percentile of national industries). 66% of the establishments have fewer than five employees, which marks it as a small-business industry.
By establishments it ranks 1st of the 2 codes at this level within Oil and Gas Extraction, with 74.2% of them.
