The home ownership rate has been rising steadily since 1970.
One of the aspects of the buildings and dwellings statistics (StatBL) is to quantify the Swiss housing stock and to analyse it according to certain characteristics such as the number of rooms or surface area. It is an exhaustive survey, based on the Federal register of buildings and dwellings. All dwellings are included, regardless of use.
The analysis of housing conditions is another aspect of the StatBL, whose data are partly drawn from a sample (structural population survey), and partly from a register-based survey.
In 1990, the Swiss housing stock comprised 3.2 million dwellings. In 2017, it was 40% larger. Data on the annual growth of dwellings can be found on the construction statistics page.
Marked differences can be observed regarding the construction period of dwellings and of the buildings in which they are located.
In Switzerland, in 2017, almost one dwelling in four is located in a single-family house. In urban regions or regions close to an urban centre, multi-family houses are the most common type of accommodation: almost half of all dwellings are located in buildings with more than six dwellings.
