Hey, I'm Hans Rosling! And to me, the most important report in September every year is, "Levels & Trends in Child Mortality", published by Unicef, World Health Organization, the World Bank and the United Nations. The best statisticians in the World have compiled reports from all countries, and what does it tell us? The number of deaths in children keeps falling, and the rate it's falling with is even faster than it used to be. Good news in september, this year! What does it mean? If twenty children are born in the world (these are twenty children), today it's one of them that tragically dies before their fifth birthday. We have 5% child mortality in the world. That's too much, but it's much better than before. Just in 1990, there were twice as many children dying.
