Today we're going to look at the topic of human happiness and try to answer two main questions. Firstly, who are the happiest people in the world? And secondly, what makes them happy? Let's start with the World Happiness Report, which has been published annually by the United Nations since 2012. It is written by experts in the fields of psychology, economics, sociology and statistics and draws on data collected mainly in worldwide public-opinion polls. Erm ... and it provides us with a happiness ranking for 155 countries. The latest report published in 2017 ranked Norway as the happiest country, pushing three-time winner Denmark into second place. These countries were followed closely by other wealthy nations, including Switzerland, Canada and New Zealand ... And, not surprisingly, the unhappiest people were found to live in some of the world's poorest places—Central African Republic and Rwanda. So is the answer to my second question money? Well partly, yes, but it's not the only factor. According to experts, although money is important, it's also a question of whether that money is used in the right way. In order to be happy, people need to have access to a universal education system and good working conditions.
