A Growing Ink Blot Map of World Population Density

Most of our world maps are created with geographic and legal boundaries dictating how they are drawn… it’s highly useful for getting around the block, but hardly tells the whole tale of what is going on. What really matters much of the time? It’s all about where the people are… and this map shows only that.

Derek Watkins, a graduate student in Geography at the University of Oregon, has created a map that looks something like spilled ink and shows population density around the world. The flash based map features a slider, allowing viewers to adjust the view between densities of 5 people per square kilometer all the way to a sardine can tight, 500 people per square kilometer.


What really stands out about the map is the excess and lack of densities around the globe. Places like the Sahara, Siberia and surprisingly much of Australia show very little population, appearing as white as the ocean even at the lowest density. China and India, on the other hand, are still well represented on the map even at the seriously dense population of 500 people per square kilometer.

What does this map show overall? Really, it shows that even with the worlds immense population now over 7 billion people, there are still vast amounts of lightly populated area… and that’s not even mentioning the worlds oceans. For an interactive look at the map, see Derek Watkins website… or for a previous post about his work, see his mesmerizing animated map tracking U.S. expansion through the postal system.
