What makes people happy? This question can be difficult to answer. Happiness has been discussed throughout history. Philosophers, thinkers and activists, such as Aristippus, Aristotle, Zhuangzi, Jean Jacques Rousseau, Jeremy Benthan and Bertrand Russell, have considered happiness and life satisfaction to be one of the highest goals of human motivation.
But happiness and life satisfaction can be tricky to define. While both make up part of a person's well-being, happiness refers to an individual's emotions, feelings or moods. Life satisfaction, on the other hand, is more to do with the way people might think about their life as a whole – including their relationships.
Previous research suggests the "happy person" is young, healthy, well-educated, well-paid, optimistic and extroverted. The same research found the happiest people tend to be religious, married, with high self-esteem and job morale and modest aspirations. It seems your gender and level of intelligence don't necessarily come into it.
Research suggests that around the world, over 84% of people belong to or are connected to a religious group. And our recent research looks at whether different religions experience different levels of happiness and life satisfaction. The findings show that individual religiosity and their country's level of development both affect people's happiness and life satisfaction.
