House Price is rebuilt from licensed files, not queried from a live database. A Python build reads committed raw data, computes summary statistics, and writes the HTML, JSON and sitemap. A failed download can retain a previously downloaded raw file; each page shows the observation date and selected source.
Ingest and selection
- Eurostat PRC_HPI_Q is read for unit I15_Q and purchase TOTAL. Under this build's current-vintage rule, a series is eligible only if its last observation is in 2023 or later; this threshold does not mean every series is equally recent.
- The OECD HOUSE_PRICES full CSV provides measures HPI, RHP, HPI_YDH and HPI_RPI, with a recent extension where available. The incomplete SDMX-JSON all/all vintage is not used for long history.
- For nominal HPI, eligible current OECD and Eurostat series compete by calendar-year span. The longer history wins; if spans tie, the later last quarter wins. The build never joins observations from two sources into one series.
- A current UK House Price Index takes precedence for the United Kingdom. Its monthly United Kingdom index is averaged into quarters, then rebased so the mean of the 2015 quarters equals 100. It is not spliced to Eurostat.
- For Australia, a current OECD HPI with at least ten calendar years is preferred. Current ABS mean dwelling prices, rebased to 2015=100, are considered only if the selected index is stale or spans less than ten years; the ABS series must still offer the better eligible history. Mean prices are not a quality-adjusted HPI.
- Year-over-year change is derived by Younivi as (index / index four quarters earlier − 1) × 100. It is labelled derived, not an official agency growth series. Real HPI uses OECD RHP; price-to-income uses HPI_YDH; price-to-rent uses HPI_RPI.
- OECD euro-area code EA is mapped to the euro-area desk EMU. OECD, EA17 and WXOECD aggregates, and China and Russia, are excluded by this build. Only series with at least four observations appear in the headline index; rankings use each economy's latest available quarter.
What we do not do
We do not interpolate missing quarters, splice different source vintages, or substitute series from other publishers such as CoreLogic, FHFA or BIS. RBNZ M10 is not ingested because of access and provenance limits. Rebasing the UK HPI and a selected ABS series changes their scale only, as their citations explain.
Charts and tables
Charts use quarterly observations. The all-countries chart initially selects the twelve highest latest readings; its legend and filter can change the selection. Country views show the selected economy and related peers. Chart and table use the same data, and range buttons only change the visible window.
