Since most of us spend a great deal of our lives working, it is inevitable that work plays a key role in shaping our levels of happiness. In a recent chapter of the World Happiness Report — published annually to coincide with the United Nation’s International Day of Happiness — we look more closely at the relationship between work and happiness. We draw largely upon the Gallup World Poll, which has been surveying people in over 150 countries around the world since 2006. These efforts allow us to analyze data from hundreds of thousands of individuals across the globe and investigate the ways in which elements of people’s working lives drive their wellbeing.
