Well, if residents of Serbia left for BiH during or after the bombing and stayed there, they wouldn't be counted in the census -- or would they, if they retained Serbian citizenship? Hmm. Maybe Kosta knows.
If they were refugees from BiH or Croatia who went back home, then they wouldn't be counted either, I suppose. That's why I used the UNHCR December 2001 figures to estimate the number of refugees still inside Serbia.
Maybe I'm missing your point about the census and not understanding something.

Yes, lets ask kosta50. Because those Croats that left Serbia, wasn't it around 20,000? - they would still be citizens too, right? I never heard of Serbia taking the citizenship from ethnic Croats or anyone, have you? So, I think the census probably reflects who is there, or lives there for a certain number of months in the year.
Maybe they would lose citizenship if they became citizens of certain other countries that don't allow dual citizenship.
