Analysis
NAICS 6221 is the 2022 industry group for general medical and surgical hospitals, part of 622 (Hospitals).
It has only one more detailed code, 622110, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 5,777 US establishments in this code in 2023, employing 5,815,843 people at an average annual payroll of $81,223 per employee (70th percentile of national industries). 10% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 1st of the 3 codes at this level within Hospitals, with 76.8% of them.
Between 2018 and 2023 the number of establishments grew 6% 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.
