Is the World Really Overpopulated?

The notion that we’re headed towards some kind of populational apocalypse—that there exists a line which, once crossed, will lead inexorably to mass starvation, and a whole planet like King's Cross at rush hour—has been used to stoke fear and sell books for more than a century.

The Map of the World if Every Country Had a Population of 100 Million

Imagine a world with countries reshaped to have an equal population with each other. Some little countries get absorbed to create one large country while other populous countries get their boundaries re-drawn and are split up into lots of different pieces (I'm looking at you China and India).

We've seen a lot of world population maps, but this might just be prettiest one yet. Simple black lines trace the population by latitude, so that a few cities, labeled in yellow, tower like the skyscrapers over the land.
