assembled from the two files above | 2026-10-30 | — |
Columns of the vintage files: date (first day of the month, ISO), cpi (index level, 3 decimals). The assembled file adds vintage (the vintage date of the extract the value was taken from). The raw downloads were reformatted (two columns, ISO dates) without changing any value. An empty cpi cell means the source publishes no value for that month. The assembled file was produced by hand and may contain assembly errors.
