200 Countries, 200 Years, 4 Minutes

In a previous posting, I pointed you to a video featuring Professor Hans Rosling of Sweden as he took us visually through population growth from 1960 to the middle of this century. Now he's back with a new video called "200 Countries, 200 Years, 4 Minutes," which in four minutes dramatically visualizes the improvement in life expectancy over the past 200 years, using data from 200 countries (albeit not all countries have data for all years). This video is part of his BBCFour series on the "Joy of Stats" and it is available on the internet from: http://www.wimp.com/countriesyears/  Enjoy!
