About Worldmapper

Introduction

This website contains a large collection of maps (and associated information) that we are in the process of generating. Each map relates to a particular subject. Click on the 'Thumbnail Index' which gives thumbnail previews of the maps, 'Map Categories' which is classified to see the choice, or a new option 'A-Z Map Index', and view a map and associated information. There is also a Site Map and Help page.

Coverage The maps and data files cover 200 territories, mainly United Nation Member States plus a few others to include at least 99.95% of the world's population. For a map identifying them see the labelled territory map, and for a cartogram giving them all equal prominence see Appendix A (Areas Included). Further details about their names are given in Technical Notes for Land Area. Also shown on the maps are 62 other areas, mostly small islands, which do not have unique data but are assigned to and included in the data of the 200. For details see Appendix B (Islands Assigned to Territories).

Cartograms The maps presented on this website are equal area cartograms, otherwise known as density-equalising maps. The cartogram re-sizes each territory according to the variable being mapped. See About the Maps. To get a higher resolution map, click on it.

Colours and regions 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. You can view a labelled territory map with the territories labelled, and also a labelled regions map .

Posters and high-quality pdfs Each map page gives a link to a poster. This is a pdf file which has a higher resolution map and some extra information in a chart or table. It is also designed to be printed out.

Data files When you choose a map to view, there are links at the bottom to download a data file giving the values used for all 200 territories, a graph (usually a cumulative frequency one) of the data, and a top 10 or 20 table (and the original data used, and its source).

It is important to note that all of the datasets that are used for the Worldmapper project contains estimates, approximations and inaccuracies. For more details see the data page.

There is also a data sources page giving details of the websites where much of the data has been obtained from.

Technical notes Each map has associated technical notes about the data and its sources. Additional information is present in the Technical Notes for the Land Area map Map. More information about the sources is in Data Sources.
