the United Nations Sustainable Development Solution Network (SDSN) has published the third round of the World Happiness Report in April 2015. Here's a look at the happiness score for each country, ranking from 0 (extemely unhappy) to 10 (extemely happy). The bubble size represents the log scale of the population of the country.
