In my European country (Switzerland), it's mandatory to notify the government whenever you move. There is thus no universal census and also no voter registration. There's still subsampled surveys though, for e.g. economic data, that might come by mail (addressed to you by name, because they know where you live!).
As I understand it, in the Soviet Union you had to get government permission before moving. Whereas here the right to move is guaranteed, you just have to update your details.
What's the fine for not registering your move? What time do you have to update your location?
In Russia in the 90s we had 5 days and now it's three months. The fine is 3000 rubles (~40 euro) and zero if you moved in the same region (most of them are bigger than Switzerland:) or live at relative's or spouse's place
I used to think that what we have in Russia is Soviet legacy (albeit relaxed) and it's something people in Europe are not burdened with
Many countries effectively have a live registry of where people live, updated to within a few weeks.
A door to door census isn’t needed because they can do something like:
SELECT a.province, COUNT(DISTINCT b.id_num)
FROM registry a
INNER JOIN national_id b
ON a.nat_id_num = b.id_num
WHERE timeframe = 2026-01-01
GROUP BY 1
Correct. At least, not that I know of. On the other hand, when you move, you must deregister with your old municipality and register with your new one. The exact system differs a bit per country.
