The urban districts used in Wüest Partner's price statistics were specifically defined for this purpose. In the case of Zurich, Bern and Lausanne, they are based on the official quarters, in Basel and Geneva on postal districts. The urban districts defined for Lausanne do not embrace all parts of the city. Details of the official quarters and urban districts used by Wüest Partner are provided in the following PDF documents: Zurich, Basel, Bern, Lausanne and Geneva.
Apart from the urban districts, the municipalities (currently numbering some 2,700) represent the smallest geographical unit employed.
The associated definitions, which match the official municipal coding system used by the Swiss Federal Statistical Office (BFS), are annually updated, mainly in the wake of municipal amalgamations. The municipal code for the analysed geographical area is shown in the field «Geographical coding» of the relevant caption, e.g. OG-2000.
Spatial mobility (MS) regions
A further official geographical breakdown makes use of the so-called spatial mobility or «MS» regions specified by the Swiss Federal Statistical Office (BFS). These are based on the «mobilité spatiale» model, developed by Schuler/Joye, which divides Switzerland into 106 market regions (see Map of regions).
The 26 cantons represent the next larger geographical units.
Monitoring regions, market regions
For the presentation of residential data, the spatial mobility regions are grouped into eight market (monitoring) regions (see Map of regions).
A similar grouping for commercial properties features five market regions (Zurich, Basel, Bern, Geneva and rest of Switzerland).
Whole of Switzerland
The entire geographical area of Switzerland constitutes the largest unit employed.
