Watched this video (in italian).
Happiness (calculated here ) on the left, GDP on the right. The order is not the same, and that almost says it all. A bit surprised about northern countries with low sunshine hours, as it’s demonstrated that sunshine helps with serotonin, but that deserves another post.
Another interesting one, putting income and happiness on a graph. Of course, that needs to be related to buying power, but gives an idea on how some cultures seem to be happy with lower income.
