The World Database of Happiness is an archive of research findings on the subjective enjoyment of one’s life-as-a-whole. It brings together findings that are scattered throughout many studies and provides a basis for research synthesis.

Conceptual focus

This database is about the subjective enjoyment of one’s life as a whole. This concept is spelled out in more detail in Chapter 2 of the Introductory text to the Bibliography of Happiness: Concept of Happiness. Though usually called ‘happiness’, this matter is also denoted by different names, such as ‘life satisfaction’ and ‘subjective well-being’ (SWB).


Finding pages
The building blocks of the database are electronic pages, which contain standardized descriptions of either a scientific publication on happiness, a measure of happiness used in an empirical investigation or a research finding on happiness. Pages are gathered in collections, pages on which a publication is described are stored in the Bibliography of Happiness, pages on which a measure of happiness is described are gathered in the collection Measures of Happiness and pages on which a research findings is described in the finding collections; the collection of Distributional findings and/or Correlational findings. Various reports are selected from these collections. A schematic overview of these elements is found here.
