Of course I'm aware of that, NJ.
As to the data itself -- well, you are welcome to dismiss the conclusions, but it may be very self-defeating to do so. It's hardly that surprising anyway that, for example, the younger generation tended to vote in favour of remaining, if nothing else because of the "better the devil you know" principle, and anyone born after say 1970 will have known nothing but the EU. This is a point made by many on here -- oddly, the same people who are also dismissing these results that would then confirm their expectations!
Even the apparent correlation between voting patterns and education level in a ward shouldn't come as a surprise. Ask pretty much any university (and most of its staff) what they would have preferred and the answer was universally to remain in the EU. Whatever the reasoning behind this decision, that was the preference. And, lo and behold, Cambridge's city centre comes out with the highest pro-Remain vote, and it seems that in general (although not always) a high student population was associated with a higher remain vote.
Ignoring those patterns is self-defeating -- not because it insults the leave-voting majority as uneducated, but because it betrays deep divides that should be addressed, rather than ignored. Whatever the reasons behind these correlations, they deserve to be understood.
