Created partly because of my love for quizzes that have one answer that just seems to come out of nowhere. (i.e. Argentina being home to people of Welsh ancestry, incidentally the largest community of Welsh speakers outside of Great Britain.)
Wales, Scotland, England and Northern Ireland are all part of the country known as the United Kingdom. If you're treating them as separate countries for the purposes of this quiz, you should note that in some way so people doing it know in advance.
Yeah, there are 2M of us.
