Analysis
NAICS 621 is the 2022 subsector for ambulatory health care services, part of 62 (Health Care and Social Assistance). Census lists 257 example activities under it in the official index.
By establishments it ranks 1st of the 4 codes at this level within Health Care and Social Assistance, with 69.9% of them.
Between 2018 and 2023 the number of establishments grew 12% and employment rose 15%. 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.
