The World's wealth analysed

'Hans Rosling's famous lectures combine enormous quantities of public data with a sport's commentator's style to reveal the story of the world's past, present and future development. Now he explores stats in a way he has never done before - using augmented reality animation. In this spectacular section of 'The Joy of Stats' he tells the story of the world in 200 countries over 200 years using 120,000 numbers - in just four minutes. Plotting life expectancy against income for every country since 1810, Hans shows how the world we live in is radically different from the world most of us imagine.'

Fascinating presentation and a very interesting subject BUT the X-axis is not exactly linear is it? A ten times difference in income looks like only a doubling of income. The income gap between the industrialised and non-industrialised countries is much larger than the graph seems to show. Likewise whilst the majority of African countries saw their per-capita income rise by a factor of less than ten times the majority of western industrialised countries increased theirs by a factor of 100.
