Sincere question: what do you mean by "other populations"?
HN does not provide a representative view of any group other than "HN readers".
It doesn't even do a great job of representing programmers, or people who work in tech. So if you come to HN and expect the things you read to be representative of any group broader than that, you'll end up pretty far off the mark.
Same goes for any other site that people comment on...

I guarantee you that readers with opposite views to yours have opposite views of HN's "recognizable slant". Compare https://news.ycombinator.com/item?id=16397133 to https://news.ycombinator.com/item?id=16407769. Or https://news.ycombinator.com/item?id=16134205 to https://news.ycombinator.com/item?id=16750306. And so on.
Sorry, but is this claim based on pageviews, or the origins of the comments being posted?
It's not like guardian.co.uk/international is in fact international news and opinion.
The point, though, is that people coming here are coming from many different countries, so opinion is more divided than it would be from just one. There aren't only political and ideological divides, but national, cultural, and linguistic ones. Understandably—because the information isn't available—people don't take this into account. That unfortunately leads to a lot of misunderstanding and even ill will.
Why not make it available?
A vague question
The numbers depend on how you measure 'user' and 'location'
Gets a vague answer.
My question was specifically about the commentariat not eyeballs.
I don't think myself as worthy of an answer specifically to me. I think it would be for the best benefit of others if not buried in some obscure thread.
