“Worldmapper is a collection of world maps, where territories are re-sized on each map according to the subject of interest.
There are now nearly 700 maps. Maps 1-366 are also available as PDF posters. Use the menu above to find a map of interest. In 2009 we added a series of maps of the world’s population using a gridded cartogram approach: Worldmapper Population Atlas
