"Check your math, and your reading skills, Snail. I figured most people would understand the lily-white area begins 50 miles north of London (and note that I said the inland area)"

I agree with TheSnail - this is simply dead wrong.

My paternal family hail from the East End of London and some were Huguenot immigrants, I grew up on the outskirts of Brum, live south of Manchester and was in Bradford last week; these areas have diverse and vibrant ethnic populations and have for years. The Balti curry first came to the UK when it was sold in the balti houses of Sparkbrook.

Rurally racial diversity is undoubtedly less, but I think you'd be surprised at the number of languages and cultures many small towns contain these days, and long may it remain so.

There's a hell of a lot more to the UK than London. Thank god.
