Pretty sure last time someone asked this question, the reply was something like "There may be multiple guides, that all have different data and statistics, and not everyone may use the same guide." I could be wrong though, and this is just a guess. Plus, some people don't like the villager tiers at all, and would maybe complain...

Oh and another thing, I guess you could say that there could never be an official villager popularity guide, because they constantly change, and as we saw with HounD00med's guide, some people simply cannot continue to keep guides like this up to date. Hound00med did have a stickied guide I think, but they could no longer update it, and it had to be unstickied.
