But the evidence we have so far is that only in the case of intra-European mixing do we have evidence of successful assimilation to a common "American" or "Canadian" culture. Canadians in the 1960s from different European backgrounds were well assimilated, despite their ethnic differences, to Canada's Anglo heritage. Once we look at the data for black and White integration, in the case of the United States, for which we have the most data, or, for that matter, White and Indian integration in Canada, Australia, and the US, we find that tensions, ethnic segregation in places of living, where children go to schools, and in cultural activities, have not declined one bit, even though all blacks and Aboriginals now enjoy the same civic rights. The evidence shows, to the contrary, that the closer to each other different races live, the less tolerant they are of each other.
