Happiness is definitely subjective, which means that it's particularly challenging for people to decide what makes one place happier than another. After all, a stunning vista with trees and mountains might be a city dweller's idea of misery. Luckily, it's not up to us. The Happiness Research Institute charts the feelings and emotions of people from countries around the world. It factors in how people feel about themselves, as well as how they feel about the world around them.
