Least Diverse Countries

Name the world's 25 most ethnically homogeneous countries, according to Wikipedia, the universal authority on this sort of thing.
All answers are sovereign countries. Many in the study are colonies/protectorates/whatever, but I ignored those.
According to Alesina et al's assessment, which uses ethnic groups listed in the Encyclopedia Britannica but does not make judgement calls on which ethnicities are "more salient than others. "
