U.S. Census Bureau

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.

Current experimental annual Census product supplementing AIES with employer-firm capital-expenditure estimates beginning in reference year 2023. It publishes total, buildings/other structures, and machinery/equipment expenditures with coefficients of variation by selected 2017 NAICS levels. Geography is U.S.-national for all in-scope sectors and state-level only for manufacturing. The April 30, 2026 release is a public XLSX; no product-specific API or bulk schema beyond that full file was found. Values are disclosure-protected, carry D/N/S/Z/v/w qualifiers, and are not a seamless continuation of ACES.

Final 2023 All Sectors Basic Summary Statistics. API, FTP, and table surfaces publish aggregate sales/value of shipments/revenue, payroll, employment, CVs, flags, 2017 NAICS, and geography for U.S. private-sector nonfarm employer companies. Values are nominal. The final release supersedes First Look. Current output has only 2023; it is not yet a self-contained multi-year trend.
