Firm count

Annual aggregate measures of establishment openings and closings, firm startups and shutdowns, employment, and job creation/destruction. The current 2023 release covers 1978–2023 for the 50 states and DC through national, state, county, CBSA, metro/non-metro, NAICS 2017, firm/establishment age, and size tabulations. A coordinated 56-file Puerto Rico extension covers 1998–2023 at 2-digit NAICS and specified geographies but is available only as CSV. Release documentation pins stateside geography to the 2023 vintage; the generic API geography metadata still reports referenceDate 2022, so consumers must retain this documented metadata conflict. Measures are annual March-to-March, not individual-business records. Historical values can receive minor revisions, with recent births and job flows especially revision-sensitive.
