If you're happy and you know it, smile and get someone to take your picture — it might just mean you're in one of the happiest countries in the world.
That's the idea behind a new ranking of the world's happiest countries to coincide with the second-annual International Day Of Happiness.
The study, produced by Jetpac, doesn't exactly scream "scientific accuracy" like the reports the The Organisation for Economic Co-operation and Development which ranks countries on happiness by gauging people's satisfaction with life. Instead, the study combs through 150 million Instagram photos to rank 124 countries based on the number and size of the smiles in the photos. Smiles are scored on a scale of zero to 100 with the bigger the grin, the bigger the ranking.
Canadians finished with the top 50, ranking 45th with a smile score of 26.7, ranking just below Israel and above Myanmar. To see where the "happiest" or (at the very least) smiliest countries are, take a look at the gallery below.
