Well, I live 20 miles from Birmingham, so the pattern is the least Third Worldish constituencies of Birmingham still voted for the Tories.
i.
The best example will be Sutton Coldfield where the Tories took 60.4% of votes, while the Labour took just 23.6%

White British people are "overrepresented" there and the population is older than the West Midlands' average on top of that. That's the only part of Birmingham that (still) looks like England. It's posh and clean. The rest simply looks like a different planet rather than just a different city.

They voted for the Labour, but not 80% of them at least:

Also, in these two, certain names are visible rather than overrepresented
