In a follow-up to his now-legendary TED2006 presentation, Hans Rosling demonstrates how developing countries are pulling themselves out of poverty.
He shows us the next generation of his Trendalyzer software -- which analyzes and displays data in amazingly accessible ways, allowing people to see patterns previously hidden behind mountains of stats.
He also demos Dollar Street, a program that lets you peer in the windows of typical families worldwide living at different income levels. Be sure to watch straight through to the (literally) jaw-dropping finale.
I have to say it's not as impressive the second time around.
