The breadth of the blue isn't surprising — the Amazon basin, the northern areas of Amerca, Siberia, Greenland, Australia, the Sahara, most of it expanded by a Mercator projection — but the tightness of the red (um … Bangladesh, mostly, it looks like) is a bit more of a shock.

This Map’s Red and Blue Regions Each Contain 5% of the World Population
The remaining 90%, of course, inhabit the regions colored white. (That’s how math works!)
