This Map's Red and Blue Regions Each Contain 5% of the World Population

The remaining 90%, of course, inhabit the regions colored white. (That’s how math works!)

The map above was created by data cruncher Max Galka using QGIS, a free, open source, all-purpose mapping tool. According to him, the map is an amended version of another chart firstcreated by redditor Ibisdigitalmedia. “The original map turned out not to be entirely correct (the red region covered only about 3% of the world population),” he says, “so I made this one from scratch based on the same concept.” (For the cartography nerds: Galka says he used a Miller Cylindrical Projection, “because I see it as the closest to the way people are used to seeing the world. Since there are no country borders, I wanted to make the land areas as recognizable as possible.”)

Galka tells io9 the majority of the territories that fall within colored regions are entire countries. For those, he says, “the population figures are from the Credit Suisse Global Wealth Databook.” In a few cases, however, “only select states / provinces of a country are included in the colored areas. Those population figures were pieced together from various sources.”
