The World Database of Happiness (Veenhoven 2012) is findings archive, that is, a collection of observations that result from scientific empirical research. The database focuses on research findings on happiness in the sense of subjective enjoyment of life. Its goal is to facilitate accumulation of knowledge on this subject. The database consists of several collections. It builds on a collection of all scientific publications about happiness, called the ‘Bibliography of Happiness’ (Veenhoven 2012a). To date this collection includes some 7000 books and articles, of which half report an empirical investigation that used an acceptable measure of happiness, listed in the collection ‘Measures of Happiness’ (Veenhoven 2012b). The findings yielded by some 3500 studies that past this test for adequate measurement of happiness are described on separate ‘finding pages’, using a standard format and a standard terminology. Two kinds of findings are discerned: distributional findings on how happy people are at a particular time and place and correlational findings about the things that go together with more of less happiness in these populations.,
