I had an argument on here ages ago about how multicultural England actually is, some people were arguing that only 46% of the country was white british these days, I was arguing that it was more like 83% as that's the figures in all the government censuses and surveys.
The counterpoint to that was the sort of people who don't fill in censuses or answer surveys are less likely to be white british than the sort of people who do. So it's probably impossible to get an exact figure with adults.
Fortunately children all go to schools and you can survey them pretty accurately so here's a map of school data.
The whitest part of the country is Durham at 97.4% white. The least white is Tower Hamlets, where only 15.1% of children are white.
So basically anyone who's moved to Durham recently is probably a massive racist who is running away from blacks.
