GeoJSON dataset with median asking prices per statistical sector (NIS code) for all of Belgium. Split by property type: house versus apartment. Updated monthly. A breakdown by year built and EPC will follow in a later release.
The Taxon Price map is a GeoJSON dataset showing median asking prices per statistical sector for all of Belgium. It provides a geographical overview of the property market at the most detailed level.
Every sector contains median prices, the number of reference points and price evolution over time.
Filter between house and apartment for targeted analyses. Additional filters (year built, EPC, period) will follow.
Directly integrable into Leaflet, Mapbox, Google Maps, QGIS and any GIS platform.

Limit results to a specific price bracket (e.g. €200K-€400K) for targeted searches.
Filter by region, province, municipality or specific statistical sectors.
Filter sectors with a minimum number of reference points for statistically reliable results.
