200 Countries, 200 Years, 4 Minutes
About this video
Hans Rosling charts the wealth and health of 200 countries over 200 years to reveal a converging world.
Now that there are seven billion people on the planet we thought we should post this great video from the king of data visualisation, Hans Rosling.
The clip is taken from the BBC Four series, The Joy of Stats but Rosling has become known worldwide for his visual presentation of complex data. As he says himself in the video:
"Having the data is not enough – I have to show it in ways that people both enjoy and understand".
Using augmented reality animation Rosling plots the income and life expectancy of 200 countries across six continents over 200 years using 120,000 data points. Sounds complicated? The result is a thing of clarity and beauty.
Despite sudden drops in life expectancy for global catastrophes (the first world war and Spanish flu epidemic are the most notable) the data shows the developing world catching up with the West. Rosling ends by proposing that, if the trend continues, "everyone can make it to the healthy, wealthy corner".
There’s lots more from Hans Rosling on TED.
