Between 2018 and 2023 the number of establishments grew 9% and employment rose 8%. 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.
For example, holding the securities or financial assets of companies and enterprises for the purpose of controlling them and influencing their management decisions are classified in 551111 (Offices of Bank Holding Companies, or U.S. Industry 551112, Offices of Other Holding Companies) instead.
