- Used on
- STORY-05, PROB housing
- Known limits
- The rent index is the rent component of the CPI (quarterly survey of rented dwellings); it is not an index of asking rents for advertised dwellings. Do not compare index levels across bases — compare changes, or use one base for the whole period (1939-08 covers all months). The BFS methodology report "Mietpreisindex: Methodenbericht" (2022) describes the survey.

Transformations
- XLSX cc-d-05.06.01.17 "LIK, Mietpreisindex auf allen Indexbasen [MPI MULTIBASIS]": sheet MPI_m (monthly values) → period YYYY-MM, period_type month; sheet MPI_y (yearly averages) → period YYYY, period_type year_avg. Base columns read from the header row "Datum / Date" (Excel date serials → base month). Script: scripts/fetch/bfs-rent-index.ts
- Index values rounded half-up to one decimal (BFS publishes one decimal; some XLSX cells hold float noise or unrounded averages, e.g. 2021 yearly average 1142.612…). The fetcher checks that every base is 100.0 in its base month.
- The monthly sheet repeats the latest quarterly survey result in the months between surveys; use the survey months (Feb, May, Aug, Nov) for quarter-on-quarter changes.
