So, it looks like there has been a lot of improvement and success with cultural integration from nations that share a similar heritage. I've also been told that many Indians and Jamaicans have integreted fantastically since the 70s and 80s (look at our very own Romesh, he couldn't be more British). But it also looks like there has been trouble with integrating other cultures that aren't as recipient to assimilation. Looks like London is the perfect example of culture-compatibility.
I've always been fascinated by rural England, particularly in the south as I've come to believe that is where my heritage originates.
