Next national census in Poland happens in 2021 and also here, you can be fined or sent to prison, get non-custodial sentence by not participating or providing false answers; persons covered by census are obliged to participate. Those who by gathering answers for census surveys and processing data will gain any profits can be imprisoned for up to 5 years.

So far no one from my family was chosen; since fall of the Eastern bloc there were 2 censuses, in 2002 and 2011
