I think Canada, Australia, South Africa, Russia, and Brazil would dispute that.
Russian 81.5%
Tatar 3.8%
Ukrainian 3%
Chuvash 1.2%
Wow! That is one diverse nation!!! How about Australia?
Caucasian 92%
Asian 7%
Aboriginal and other 1%
South Africa has a more diverse mix, certainly:
Black 75.2%
White 13.6%
Indian 2.6%
Other 8.6%
That's a mixed plate, isn't it? And all of those ethnic groups in South Africa are known the world over for their deep love of one another, aren't they??! Canada? As of 2002, their ethnic groups broke down as follows:
British Isles 28%
French 23%
Other European 15%
Amer-Indian 2%
Other 6%, mostly Asian
Being in Michigan, I frequently visit Canada, at least once a year, sometimes more. White white white white white. Sure, that's diverse. /sarcasm
Brazil? You're right, they come awfully close.
