I did a very basic search for racial demographics of Sweden, the US and Brazil (since someone else mentioned it), then calculated the Shannon diversity index (lower essentially meaning less diversity) and the Pielou evenness (a number between 0 and 1 - higher means less size variation among groups). I didn't find great numbers to work with in the few minutes that I looked. I used these: US: http://en.wikipedia.org/wiki/Demographics_of_the_United_States#Race_and_ethnicity http://en.wikipedia.org/wiki/Demographics_of_the_United_Stat... Brazil: http://www.indexmundi.com/brazil/demographics_profile.html http://www.indexmundi.com/brazil/demographics_profile.html Sweden: http://www.populstat.info/Europe/swedeng.htm http://www.populstat.info/Europe/swedeng.htm And got: US: With Hispanic/non-hispanic breakdown Shannon: 1.258355 Pielou: 0.5064 Without breakdown Shannon: 0.9705 Pielou: 0.4987 Sweden: Shannon: 0.4498 Pielou: 0.2795 Brazil: Shannon: 0.9509 Pielou: 0.5908 So in terms of diversity, US >= Brazil > Sweden.
