This indicator is an index of the quality of living conditions. The average living surface par occupant depends on the number of household members and the dwelling’s surface area. When interpreting the results, one should also bear in mind that people with a migration background are more likely to live in towns and cities, where dwellings are generally more expensive and smaller. All other things being equal, this has an impact on the living surface available for each occupant.
In single-person households, an average difference of 14m2 can be observed between the population with a migration background and that without (70m2 compared with 84m2). This means that single-person households with no migration background have almost 1.2 as many square metres as those with a migration background. In households with two or more occupants, although the average absolute difference is 13m2 between persons with and without a migration background (32m2 compared with 45m2), the relative difference is greater (1: 1.4). Mixed households have an average of 35m2 per person.
Overall, single-person households with no migration background show little difference in terms of living surface from those with a migration background. However, a clearer difference can be observed in dwellings with six rooms or more, where households with a migration background have more living surface on average than those without a migration background (+15m2).
Households with two or more occupants
In dwellings with one to five rooms, households with two or more persons without a migration background always have more square metres per occupant than households with a migration background and mixed households. This difference reaches a maximum of 10m2 in dwellings with four rooms. For dwellings with six rooms or more, however, the number of square metres is almost the same for households with and without a migration background (1m2 difference).
In the cantons, the average relative differences varies little for single-person households between the population without and with a migration background. The lowest ratio is found in Geneva (73m2 compared with 68m2). The largest is found in Appenzell Innerrhoden (96m2 compared with 70m2).
In households comprising two or more persons, the largest relative differences between households without and with a migration background are seen in the cantons of St. Gallen, Glarus, Fribourg and Aargau (ratio of around 1.5 to 1). Conversely, they are particularly low in the cantons of Zug, Geneva, Nidwald and Ticino (ratio of around 1.2 to 1). Mixed households, on average, have a little more living surface than households with a migration background in all cantons with the exception of Geneva (30m2 for households with a migration background compared with 28m2 for mixed households).
