This visualization, a Tableau dashboard, shows happiness levels around the world. We can see that happiness levels are not distributed randomly. Rather, countries in Scandinavia have especially high levels of happiness, and many countries in Africa and some countries in Asia have significantly lower happiness levels. The United States does not make the list of top ten happiest countries in 2017. Additionally, we can see that happiness levels are more strongly correlated with having family you can count on, GDP per capita, and health, and less strongly correlated with trust, generosity and freedom.
You can find the clean data for this Tableau dashboard here. I downloaded it from Kaggle, where there is also happiness data for 2015 and 2016, along with code and analysis ideas from others.
