Danny Dorling devised this project and gathered the data together, while Mark E. J. Newman wrote the computer software for making the cartograms and produced the figures themselves, and Graham Allsopp leant his cartographic expertise to many aspects of the project, particularly the poster design. In addition, Anna Barford wrote the text accompanying each map and sourced quotes, Ben Wheeler gave advice and checked for accuracy, John Pritchard developed the website and gathered data, and David Dorling contributed his medical knowledge to the production of technical notes. The map was rendered as an equal-area cartogram, otherwise known as a density-equalizing map. The cartogram resizes each country according to its ecological footprint using a method developed by Gastner and Newman. The generally richer countries of Western Europe, Japan, and the United States have a large ecological footprint denoted by their large area size. Less developed yet highly populated countries such as India and China exhibit a similarly large footprint. Other countries such as Australia and Russia shrink compared to the land area map. The supplementary tables and chart show countries with the largest and smallest ecological footprints. The map is one of more than 500 that make up the Worldmapper project at http://worldmapper.org.
