Hans Rosling:  The Best Stats You’ve Ever Seen

Hans Rosling is a genius at stats.

When he gave his students a test about child mortality, he figured out that the students know less than chimpanzees. Also when he gave the professors the same test, they did better but still not as good as the chimpanzees. When asked about what the students knew about the world, this is what they came up with. They said the world is still we and them. We is western world and them is third world. What that means is short family and long life for western world and large families with short lives for third world. What he shows during his graph is, over time, almost all of the countries are in the same range with an exception of a few countries.

Hans then starts to compare the United States with Vietnam starting in 1964. The power point shows that even through the war, the life expectancy was still going up. The life expectancy even went up until it reached the same as that of the US. Another example he gives is about the average income throughout the world. What he realizes is that there is no gap between rich and poor anymore. When he shows the countries that make up this data, he shows that Africa is mostly in poverty while the OECD is almost all pretty wealthy. Latin America ranges from poor all the way to wealthy while East Europe and East Asia are almost both right in the middle. Hans’s stats gives us a new outlook on how the world is really doing in terms of economy and health.
