Census in Switzerland

As well as counting the number of inhabitants, respondents were also asked about their sex, age, marital status, occupation and religion.

Since 2010, the population census has been carried out and analysed annually in a new format by the Federal Statistical Office (FSO).

The new census is primarily based on a register survey that evaluates existing administrative data.

Data are extrapolated to obtain statistical results for the whole population (aged 15 years and older).

Facts that can affect the accuracy of these estimates are: the consistency of the variables recorded, the size and structure of the sample as well as the willingness of the persons interviewed to answer the questions (response rate).
