It's actually pretty amazing, but if anyone can poke a hole in the sources, I'd be very grateful.

Here's Nationmaster's figures. I believe their source is the UN.

Here's what the U.S. Census Bureau says. Their only guarantee of accuracy is our own population, though.

This one's got counters. Whee!
