This week I got a letter from the government. For once it is not about taxes or something else to pay, lucky me. Instead it is a letter from the federal department of statistics.
3% of Switzerland's citizens got such a letter where personal information (with how many people do you live, where do you work, what languages do you speak, etc) is asked.
Besides the forms there was also a letter attached, describing the purpose of the statistics. And one sentence clearly stating, that I must answer all questions:
[...] Because of this reason, the federal government has declared the participation as mandatory.
Oh well. No choice then. This one's for free, Switzerland. The next time I'll charge you ;-P.
