According to this year’s World Happiness Report, Finland overtakes Norway as the world’s happiest country.

The annual UN report measures “subjective well-being” – how happy people feel they are, and why.

According to the survey, Burundi was the least happy, taking over from the Central African Republic.

Burundi was thrown into crisis when President Pierre Nkurunziza’s bid for re-election to a third term in 2015 sparked protests by opposition supporters who said the move was unconstitutional.
