''As of 2007, there were about 393 000 non-citizens living in Latvia [1], mostly Russian-speaking.''
Wikipedia it is.
Non-citizens (Latvia - Wikipedia, the free encyclopedia)
Huh, in a nation of 2.2 million, about 393 thousand are non-citizens. [sarcasm]Seems strange. If they could all easily get citizenship, I wonder why they didn't.[/sarcasm]
No seriously. I can't recall which of the Baltic republics had a neo-Nazi parade on Hitlers birthday, but really the situation is less then pleasant.
