Mapping the World’s Population by Latitude and Longitude

This map by Datragraver shows a count of people for roughly every square kilometer on Planet Earth. The dark lines you see represent the total amount of people on either that latitude (vertical axis) or longitude (horizontal axis).

The map is an update to the below map from 2000 by Harvard Ph.D. Bill Rankin. The changes compared to 2000 are not that visible. But the Northern hemisphere got an even larger population and there has been a shift to the East.



  1. Why is it that I can’t find a graph with the latitude axis actually labelled? As soon as I met graphs in school I was taught to fully label my axes! Why have these cartographers forgotten that basic lesson? We are not even told whether the scale is linear or otherwise! Why are the tropics not shown? At what latitude is the maximum population? In addition, given that land area decreases with decreasing latitude, wouldn’t a plot of population density with latitude also be revealing?
