Compared to the maps of living-area-by-race in the US [1], it seems like there is much less segregation between black and white people in London. I wonder why this is the case? Also, I wonder why there is still heavy segregation in regards to the Asian populations in London.

I should add that the apparent mixing between blacks and whites could be because the grey and blue dots look too similar in the London map, but I still think there is more mixing than in the US.
