Differences between the North and South of England?

Cultural, economic, social, those sorts of things.
By southern England, I mean areas around LONDON more specifically than anywhere else.
And by northern england we’re talking anything between Sheffield, Manchester and Newcastle.

What do you think are the major differences?
It one more wealthy in general than the other?
More, or less cultured?
Are the people friendlier/ruder/rougher/ in one area than the other?
What about buildings and cities, which area has buildings and cities in a better ‘state’, cleaner roads? Nicer houses?

Anything and everything you can tell me about the differences (or similarities if that is the case!) between Northern and Southern England.

Oh and ACCENT! is another one, differences between those (although I know there are some obvious differences in that already.. haha, I’m not deaf!)

What about ethnicities? Is one ‘end’ of England more diverse than the other, or is it about the same? Do you think this is a problem when it comes to racial tolerance, or is it pretty much the same all over britain with a few general hotspots of racist behaviour?

Thanks in advance
