TED | Talks | Hans Rosling: Debunking third-world myths with the best stats you've ever seen (video) Hans Rosling: Debunking third-world myths with the best stats you've ever seenThe first comment sums it up well.
The speech is hilariously entertaining, informative about world demographics, and demonstration of shockingly amazing software, a example of how massive information can be conveyed efficiently, and a call for making publicly funded databases avialable for analysis - all at the same time and in 18 minutes. It will leave you stuneed. No visualization software has ever made me feel so inadequate.
A great mention in the talk is that you have to have health before you can have riches.
