These are two of the most interesting, engaging and funny Ted Talks I 've ever seen. They were given by Hans Rosling, a Professor of International Health from Sweden in 2006 and 2007. From Ted:
You've never seen data presented like this. With the drama and urgency of a sportscaster, statistics guru Hans Rosling debunks myths about the so-called "developing world."
Dr. Rosling tackles international development and the use of statistics and data in the first lecture and poverty and development in the second lecture. They truly are a must see.
