About this Gapminder Video

What’s the difference between Chile, Cuba and the USA?
Well, it depends on what kind of factors you are looking at. What is obvious however, is that an explanation of reality demands far more complex groupings of countries then in “developed” and “developing countries”.

In some aspects Cuba was closer to USA than to Chile in 1962. Today all three countries has a low child mortality but differs both in fertility rate and in income.
