Coverage: Jan 1939–present, monthly. BLS source code: CES3000000007. CSV API: https://fred.stlouisfed.org/graph/fredgraph.csv?id=AWHMAN. 1950 annual average: 40.5 hours. 2024 annual average: 40.7 hours.
6 records across 6 decades and countries. Documented gaps are included; a source cited for a gap does not establish a value.
6 of 6 records have a current source audit. A transcription check reads a declared numeric field from a pinned local source file; a calculation replay reads its operands and applies the declared method and rounding rule. A source audit does not independently validate the source or every claim in a record. The date is the last successful local audit; the build checks that its bindings still match.
