About the video
Instead of studying history for one year at the university, you can watch this video for less than five minutes.
Income per person (GDP per capita) is adjusted for inflation and for differences in costs of living (purchasing power) across countries. You can play with the data yourself in Gapminder World.
This is a short clip from the longer film The Joy of Stats ©Wingspan Productions for BBC, 2010.
