The World Database of Happiness has been conducting surveys for decades to measure the level of “happiness” across the world.
The data, until now, was only available in raw form but the very creative folks at GOOD Magazine have converted it into an easy-to-digest infographic where the “smile” in the “smiley” represents the happiness graph of a country for the last three decades.

Speaking of happiness, you should also check the Gross Happiness map on Facebook that shows how the happiness level of Facebook users fluctuates over time and the days when they’re feeling most happy. Facebook has data for US, Canada, Australia and UK.
