Density

7.4 billion people live on earth. This graphic shows where half of them live - in the light spots. The other half lives on the rest of the land, spread out all over the dark parts.

The map uses NASA's "gridded population data." It has 28 million cells, each representing nine square miles. Every cell which is populated by 8,000 people is colored yellow. 

Half of the people on earth live on 1% of its land.
