While the Harry Potter books are primarily set in Great Britain, there are various references to wizards from other countries.
Any level of canon is acceptable, but Rowling-canon is preferred.
As far as we know all countries have a wizarding population, and they all appear to have a proportionate wizarding population. We are not lead to believe that any country DRAWS in more wizards then normal. i guess in theory the old world probably has a few more old pureblood families then the new world simply by traditional movement patterns.
Bill had a penfriend at a school in Brazil . . . this was years and years ago . . . and he wanted to go on an exchange trip but Mum and Dad couldn’t afford it.
He supposed, now that he saw rep- resentatives of so many nationalities in the campsite, that he had been stupid never to realize that Hogwarts couldn’t be the only one. He glanced at Hermione, who looked utterly unsurprised by the information. No doubt she had run across the news about other wizarding schools in some book or other.
US
while a group of middle-aged American witches sat gossiping happily beneath a spangled banner stretched between their tents that read: the salem witches’ institute. Harry caught snatches of conversation in strange lan- guages from the inside of tents they passed, and though he couldn’t understand a word, the tone of every single voice was excited.
France
“They must go to Beauxbatons,” said Hermione. “You know . . . Beauxbatons Academy of Magic . . . I read about it in An Appraisal of Magical Education in Europe.”
Ireland
You’ll be supporting Ireland, of course?” she added, eye- ing Harry, Ron, and Hermione beadily.
Africa (yes continental via state)
Three African wizards sat in serious conversation, all of them wearing long white robes and roasting what looked like a rabbit on a bright purple fire
Egypt
Bill works for Gringotts as a curse breaker, and works in Egypt were the ancient Egyptian wizards set up complex curses to protect tombs.
Bulgaria
Harry — DAD GOT THE TICKETS — Ireland versus Bulgaria, Monday night. Mum’s writing to the Muggles to ask you to stay. They might already have the letter, I don’t know how fast Muggle post is. Thought I’d send this with Pig anyway.
