Hans Rosling has given nine TED Talks, each sharing a carefully measured dataset to change misconceptions about global issues. Now, the Gates Foundation shares a new demonstration from Rosling. Here, using powerful moving charts, Rosling shatters the fallacy of the “developed” world versus the “developing” world. By looking at the facts, we are able to see that child mortality rates in poorer countries have been steadily decreasing over the past 50 years. Now, those so-called “developing” countries are almost equal to the numbers of the wealthier nations. By 2030, there will be no difference.

What will persist, however? The perception. “It is only by measuring,” says Rosling, “that we can cross the river of myths.”
