In this Gapminder video, Hans Rosling shows you how all the countries of the world have developed in the last 200 years. In 1809 all countries of the world had a life expectancy under 40 years and an income per person less than 3000 dollar per year. Since then the world has changed, but it was not until after the second world war that most countries started to improve.
