Demographics is an interesting opportunity to make use of the new espionage/rumors system for the developers. It is a little silly to have a global ranking screen of all Civs, including those you haven't met, and they've expressed interest in having intelligence on other Civs being something you have to work for rather than automatically know.
If well-executed, it could be an interesting feature. Of course I won't even consider them leaving out something like a demographics screen altogether. This is a strategy game, having that kind of information is a no-brainer. It just seems like they could give us the opportunity to work a bit for it.
