Interactive maps of the world population on the INED website

Maps provide an invaluable tool for illustrating variations in demographic phenomena across countries. Even more so when the maps are interactive and provide a moving picture of changes over time. A new application of this kind, showing changes in 30 indicators recorded since 1950 and projected up to 2100, is now available on the INED website. Its designers, Gilles Pison, Hélène Mathian, Christine Plumejeaud and Jérôme Gensel present this new tool and describe how it works.

The website of the French National Institute for Demographic Studies (INED) features a set of free-access interactive population maps. Thirty demographic indicators can be visualized for all countries of the world, and users can watch moving images to see how they change over time. They can also compare a selected country with its neighbours, travel from one country toanother to see how an indicator varies, observe geographical variations of an indicator on a map without borders and last, select a point on the world map and see how the population, or another quantity, is distributed around this point.
