The Gapminder Foundation was founded back in 2005 by Ola Rosling, Anna Rosling Rönnlund and Hans Rosling in Stockholm as a “non-profit venture – a modern ‘museum’ on the Internet – promoting sustainable global development and achievement of the United Nations Millennium Development Goals.”
Its main project is Gapminder World – Wealth and Health of Nations that is based on an extensive UN database including over 430 indicators that cover unemployment, economic growth, natural disasters and many more. The example below illustrates Gapminder World with life expectancy and income (per capita) over the period 1950 to 2006 (latest version includes projection up to 2050).
The Dollar Street is another great feature. All people are assumed to live on this street where the poorest live to the left and the richest to the right (similar to a Hotteling linear version model). Selecting different parts of the street gives photo-panoramas from typical households at different income levels.
