What is this World Database of Happiness

The World Database of Happiness (WDoH)is an archive of research findings on subjective enjoyment of one’s life-as-a-whole. Next to a bibliography of scientific publications on this subject, the WDoH provides standardized abstracts of research findings. Two kinds of findings are involved: 1) ‘distributional findings’ on how happy people are in particular times and places and 2) ‘correlational findings’ on the things that go together with more or less happiness.
The WDoH allows an overview of the otherwise nebulous research literature by a) limiting to a clearly defined concept of happiness (life satisfaction), b) presenting the available findings in a standard format and terminology and c) providing fine-grained classifications by means of which users can find their way in the growing mass of happiness facts.
The WDoH is available free of charge for everybody, all over the world.
