Can money buy happiness? Not always. Special in Latin American, there seems to have no correlation between Happiness score and Logged GDP per capita. There must have other factors to make Latin America happy. It can be seen from the Q2 radar chart that, except for 2016, the contribution of Social Support factors to the happiness index ranks first in Latin America every year. Next, let’s take a look at the impact of social factors on the happiness index and GDP.

Since 2018, “social support” has the highest impact on happiness among all six factors. We tried to draw the above scatter plot to Establishing the relationship between Social Support, Happiness Scores & GDP. It can be seen from this graph that Latin American countries have higher social support scores. This can certainly explain why the per capita GDP of Latin American countries is not high but the happiness index is high. And in other factors: freedom, generosity and health expectations, the average score of Latin America is higher than that of most of the other regions.
