alt Hacker NewsDo those groups relate closely to what people generally mean by race? Race as defined in which culture? I know from personal experience that its not the same definitions across cultures. How big are those differences compared to differences within racial groups?
Take a look yourself.

Obviously some racial groups which are heavily socially constructed are not borne out by the data. There's no cluster for 'Latinos'. But in general I think there is quite a high correspondence with race as it is constructed in society and culture.
