I understand. It was just an odd thought. America has allegedly hit 300 million people, but also claims to have 12-20 million undocumented workers. That's a pretty big gap of uncertainty, in one country alone.

Europe, for the most part, has open borders. So their census is hard to judge.

Parts of Africa are still "wild" in some sense.

I wasn't questioning you, but more the establishment. It's interesting how they can pinpoint with such certainty when we hit milestones, when it seems to me they could be days, months or even a year off.
