You are right. It is not the same to measure an index with an infinitely smaller sample than that of other countries. But it is also logical that they are happy. The economist and philosopher Amartya Sen (who has just been awarded the Prince of Asturias prize in my country and already has a Nobel Prize in economics) says that the problem has to do with capabilities. That is to say, the degree of happiness depends on the degree of freedom of a country and this depends on the capabilities of each individual.

In short, in the Nordic countries they have public health, public education (including university education) etc. How can they not be happier than in India?
