Now that we finally have the 2011 census figures of France, Switzerland, and Germany, we can calculate the population figures for the metropolitan areas of Switzerland.
There exist no official statistical definition for the metropolitan areas of Switzerland (except for the part of the Basel and Geneva metro areas on French soil, where INSEE provides an official statistical definition). Here for the Swiss and German parts of the Swiss metro areas I have used either some widely-circulated unofficial definitions, or some official but non-statistical definitions (such as administrative definitions). See below the tables for exact territories included.
As a result, the total population of each metro area is only given as indicative. It should not be taken as absolute truth, especially when the metro areas are close to each other in population (for example, it is not possible to say that the Basel metro area is more populated than the Geneva metro area, because the area included in the Basel metro area is quite large and not based on a statistical definition except the part on French soil). What's more interesting is the population growth, in particular relative growth, which is little affected by the definition used for each metro area (for example, I've tried various definitions of the Zurich metro area, and the yearly growth rate is always remarkably the same, with a difference no bigger than 0.03%).
Relative growth rate of the Swiss metro areas between 2006 and 2011:
- Geneva metro area (Swiss & French parts): +1.80% per year
- Lausanne metro area: +1.60%
- Zurich metro area: +1.47%
- Basel metro area (Swiss & French parts;
no data for the German part): +0.68%
- Bern metro area: +0.43%
For comparison, the Toulouse metro area, which is the fastest growing metro area in France outside the Geneva area, had a population growth rate of only +1.34% per year between and 2006 and 2011 (a lower growth rate than in the previous intercensal periods). In Germany, the fastest growing metro area is Munich, with a population growth rate of +1.59% per year since the 2011 census (no data for the years before the census). In Belgium, the Brussels metro area (defined as Brussels-Capital + Flemish and Walloon Brabant), which has experienced a boom in the late 2000s and early 2010s, had a population growth rate of +1.28% per year between 2006 and 2011.
Absolute population growth between 2006 and 2011:
- Zurich metro area: +19,873 people per year
- Geneva metro area (Swiss & French parts): +14,241
- Lausanne metro area: +5,876
- Basel metro area (Swiss & French parts;
no data for the German part): +4,428
- Bern metro area: +1,638
Definitions:
Zurich metro area: canton of Zurich minus the districts of Winterthur and Andelfingen + the districts of Baden and Bremgarten in the canton of Aargau + the district of Höfe in the canton of Schwyz
Geneva metro area: canton of Geneva + district of Nyon in the canton of Vaud + INSEE-defined French part of the metro area
Basel metro area:
Switzerland: canton of Basel-Stadt + canton of Basel-Landschaft + districts of Rheinfelden and Laufenburg in the canton of Aargau + districts of Thierstein and Dorneck in the canton of Solothurn
France: INSEE-defined French part of the metro area
Germany: district of Lörrach + municipalities of Wehr and Bad Säckingen in the district of Waldshut
Lausanne metro area: districts of Lausanne, Ouest lausannois, Lavaux-Oron, Morges, and Gros-de-Vaud
Bern metro area: administrative district of Bern-Mittelland
Some maps at the same scale with land area and population in 2011. In those maps and area/population figures, the German part of the Basel metro area
is included. It was not included in the growth figures above because the German statistical office has not yet released the intercensal (1987-2011) population figures.
