Hans Rosling uses augmented reality animation in this episode of ‘The Joy of Stats’ to tell 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. Another interesting video on world population and wealth is Two Dollars A Day.
