Hans Rosling 7, The good news of the decade? We're winning the war against child mortality (script)
Summary
Measuring accurate number leads to knowing and solving problems. The speaker and the United Nations have cooperated for ten years to create a true data about child mortality. It made a wonderful bubbles' graphs including African data which has never ever seen.  Before 1977, in Africa, even in Kenya didn't have a system to write the death certificate at the death of the child. Thus, the interviews were done to survey. The highly professional female interviewers who sit down for one hour with  each African woman  and ask her about her birth history. How many children did you have? Are they alive? If they died, at what age and what year? This survey is costly, but it has good quality.
Accurate data would help to decrease child mortality. Vaccination and some investments also helped it and the wonderful effect was to  improve  female literacy. Each country has a different policy but the speed that some African countries can decrease child mortality will be slow though it's fully possible for all of these countries to get child mortality down.
Our next goal is to stabilize the world population. Increase population too much leads to likely terrible climate crisis. While getting child mortality down and improving female education, the world should tackle our next goals to get the good life for people in the world.
