Introduction to Happiness in Nations
Abstract chapter 6
HOW THE DATA ARE GATHERED
Data on happiness in human societies are available only for present day nation states.
These data come from cross-national surveys as well as from periodical Quality-of-Life
surveys in particular nations. This information was raked together by combing abstracts
systems, library catalogues and data-banks. Active investigators in the field were mailed.
July 1998 1027 usable studies were found from 93 nations in the period. The current number
of studies included is mentioned on the start-screen of the database-program.
