Pretty good question I would say. It’s rating your life on a scale of 1 to 10. That being said it doesn’t gauge actual happiness. For instance the Nordic countries have very high levels of depression with a third of the some countries being on antidepressants. As a whole I would say on a day to day basis people are much more ebullient and happy seeming in a lot of other places like the Mediterranean. I would wager that this doesn’t capture the percentage of time people are “happy”.
