Hans Rosling had a question: Do some religions have a higher birth rate than others -- and how does this affect global population growth?

In Hans Rosling’s hands, data sings. Global trends in health and economics come to vivid life. And the big picture of global development—with some surprisingly good news—snaps into sharp focus.
