Wizard demographics?

Hullo, all. I was wondering whether anyone anywhere has done a bit of 
calculation wrt wizard demographics -- that is, using the few clues 
Rowling offers to estimate what wizard-world numbers are like. The 
only solid number we seem to have is the number of Hogwarts students 
(1000). A url or reference would be just fine.

Also: any speculation on what a world would be like in which almost 
everyone has attended the same school? (Frankly, argh.)

Lastly: Where would you think wizarding schools would be in your 
country? Obvious Example: the US has roughly five times the 
population of the UK; does that mean five schools? Where would you 
put them?

Woof. From the Werewoof.
