Worldmapper has been created by the University of Sheffield in association with the University of Michigan, the Leverhulme Trust and the Geographical Association. It is a collection of 366 world maps, where territories have been re-sized on each map according to the subject of interest. They include maps of international migration and refugee flows, poverty and income, education and health in addition to a whole range of other themes. Information on the methodology used to compile the maps is provided.
