U.S. Bureau of Labor Statistics

Quarterly Census of Employment and Wages

Coordinated BLS QCEW public-data product publishing covered-establishment counts, monthly employment levels, quarterly and annual wage/contribution measures, average weekly wage and annual pay, location quotients, and over-year changes by industry, ownership, establishment size, and national/state/county/MSA or other published area. Area/industry CSV endpoints, quarterly and annual single-file ZIPs, title dictionaries, annual editions, and viewer tables are delivery/version surfaces of this one Source. The latest checked 2025 files are preliminary under the BLS lifecycle until finalization with the subsequent year’s first-quarter release; files do not emit a row-level release timestamp, seasonal-adjustment field, or immutable revision-vintage identifier. Employment levels represent covered jobs, not unique persons, and published wage/contribution fields must not be relabeled as a generic payroll field.
