A little factoid not reported:
Iceland and Norway: Native caucasian population ~ 99%, minorities ~ 1%
Contrast: “Twenty-two countries—all in sub-Saharan Africa—fall into the category of “low human development.””
Actually about 10% of the Norwegian population are recent immigrants. Minorities mean mostly Sami (Laplanders). Check out Wikipedia. Icelanders are descendants of scandanavians and their Irish slaves and they pretty much constitute 100% of the population.
