The Large And Small

Worldmapper is a collection of world maps, where territories are re-sized on each map according to the subject of interest. New maps are being added during 2006. The maps presented on this website are cartograms, otherwise known as density-equalising maps. The maps of the world you are used to seeing attempt to represent countries according to their land area. A cartogram re-sizes each country (or other geographical unit) according to some other variable - for example population, GDP, number of people with AIDS, etc. In the population example, densely-populated country such as the UK will appear much larger than it does on a standard map, and sparsely populated countries will appear smaller. The colours used on the maps group the territories into 12 geographical regions, and allow for an easier visual comparison between the maps than would otherwise be possible. The shading of each territory within a region is consistent throughout all of the maps, and helps to make the borders clear, and to identify each territory.
