Source notes & limitations
Kept for future Japan deflation — Official 'All items' (総合) series begins 1970. For 1955 and 1965, 'All items, less imputed rent' (持家の帰属家賃を除く総合) is the closest available series — not identical to 'All items' and flagged when used for deflation. Downloaded: cpi-all-items-less-imputed-rent-1947-recent.csv, cpi-indices-of-items-1970-recent.csv.
Where this source appears
0 records across 0 decades and countries. Documented gaps are included; a source cited for a gap does not establish a value.
0 of 0 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.
