Hans Rosling's 200 Countries, 200 Years, 4 Minutes |An Awesome Way to Teach |

What if you could see the world's history of wealth and life expectancy in a really good looking chart, like if you could see how we all went from the sickest and poorest state to where we are now. If could be awesome for us to see why the early XX century was so important to us all.

Let's get ready to see how the world was 200 years ago when we all shared misery in an equal manner, that is in 1810, when all countries in the world were sick and poor when life expectancy was 40 years or less, when only the richest countries, like the UK, had families that lived with less than 2.5K/year of today's dollars a year.

The industrial revolution caused that Europe move away from the rest, while the colonized countries in Africa and Asia were stuck at the poor and sick zone, with a rapid progress of the richest countries that got healthier a and wealthier, but then, there it comes the first world war and the Spanish Flu Epidemic (1918-1919).

Now, take a look at the 1920 and 1930, and in spite of the great depression, western countries kept on accumulating wealth, now we see Japan trying to keep up with the leaders and doing it fairly well, but still, the majority of the countries stayed down in the pit.

And then we jump to a time, after the tragedies of the second world war, let's take a look at the world in 1948. What a year, the war was over, Sweden was the absolute winner of the winter Olympics held in Switzerland after 12 years of not celebrating them, where neither Japan or Germany were invited, but the most important to us was that the difference between the countries in the world was wider than ever before, the USA leading the race, Japan catching up really quick, Iran was getting a little richer because of the oil, and the Asian giants, India, China, Pakistan, Bangladesh, Indonessia, were still poor and sick as they were at the biginning of the 19th century. But something happens, foreign colonies of Europe gained their independence and finally started to get traction and fastly run after the leading western countries, and then, countries in Asia and Latin America started to catch up with the western rich countries, therefore becoming the emerging economies.

But after that, bad things kept on happening to African countries, Congo and its civil war, Ghana was hit big time with HIV,

Today, most people have a life expectancy above 50 years, but there are huge differences at the same time from the best of all countries (Luxemburg, GDP/Capita = 88.3K/year and lifespan of 82 years) and the worst (Central Africa Republic, GPD/Capita = 599/year and lifespan of 50 years)and of course, huge inequalities within countries.

Let's watch all the above in a pretty bad ass presentation by Prof. Hans Rosling.


So, what if learning was this much fun?

Cheers.
