What makes people satisfied or happy with their lives or with particular features of their lives? In his attempt to answer these questions, the author has applied his Multiple Discrepancies Theory to study the satisfaction and happiness of university undergraduates in 39 countries. The project aims to explain global satisfaction and happiness as well as satisfaction in 12 domains: health, finances, family relations, paid employment, friendships, housing, living partner, recreation activity, religion, self-esteem, transportation and education. The forthcoming volumes of this survey will present detailed analysis for every domain, country and university, for whole groups, males and females. The four-volume set presents a thorough picture of the relative satisfaction and happiness of students in the world.
