Sometimes images like this are misleading. The idea that 1/3 of people live in China and India isn't contradicted by the relative lack of illumination. I believe it was Buckminster Fuller who developed the metric that standard of living increases in direct ratio to the power available per capita. The complete conclusion is: 1/3 of people, most of whom have a low standard of living, live in China and India.

Another, more trivial example: the Belgians put a hell of a lot of light onto their highways. It actually shows up in pictures. You'd think, based on illumination, there were more people in Belgium than there are.
