The World Happiness Report is produced by the Sustainable Development Solutions Network  for the United Nations on March 20, a date that the United Nations has declared to be the International Day of Happiness.

The report classifies countries through six key variables that support well-being: income, freedom, trust, healthy life expectancy, social support and generosity.(Here our storymap that reproduces the report on map:

We want to deepen the relationship of the six variables to each other, in particular how the GDP per capita income affects the level of happiness perceived by the inhabitants.
