Factfulness: Ten Reasons We're Wrong About the World and Why Things Are Better Than You Think by Hans Roslingwww.amazon.com
If you don't know who Hans Rosling was, check out one of his TED talks here. This book is such a great read even Bill Gate said it is one of the most important books he's ever read.
"When asked simple questions about global trends--what percentage of the world's population live in poverty; why the world's population is increasing; how many girls finish school--we systematically get the answers wrong." In this book the authors offers a radical new explanation of why this happens.
