This apparently is the population of the earth (in 2000) by latitude. I knew that most of the earth’s population lived in the northern hemisphere – but what I did not realize is that more than half the population live north of 27 deg North! That is even beyond the Tropic of Cancer!!! That would imply that more than half the population in the world do not experience the sun directly above their head ever!!
