I live in Finland, and it's very common to move out as soon as possible, which is often after graduating from secondary education (i.e. upper secondary school or vocational school). That's roughly at the age of 18. Of course there's some variance to this, and some move out earlier, some later. I'm not entirely sure about social acceptance regarding living with your parents, but I think it's thought unconventional and possible looked at a bit oddly if you're living with your parents much longer than what's typical. For example, living with your parents at the age of 25 would probably be considered a bit odd. At 30, you'd probably be considered a loser unless you had a really good reason for living with your parents.
