Every year the World Happiness Report normally compiles data from the previous three years of surveys. 

We do this to increase the sample size and keep the confidence bounds smaller. Looking at each country from 2018-2020, we find these 10 are the happiest in the world.

Factors helping to account for the variation between countries included: 

• the age of the population; 
• whether the country was an island; proximity to other highly infected countries. 
• Cultural differences played a key role as well including: 
• confidence in public institutions; 
• knowledge from previous epidemics; 
• income inequality; 
• whether the head of government was a woman,
•  and even whether lost wallets were likely to be returned.
