About this ranking
Number of firms in the private nonfarm sectors covered by the US Census Bureau Business Dynamics Statistics. Establishments under common ownership form one firm.
Excludes nonemployer businesses. Differs from active_companies, the INE DIRCE count, which includes businesses without employees.
Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
