The past decade has been characterized by a burgeoning interest in new concepts of individual and social well-being. The impetus for this new research has stemmed from increased demand from policy makers and civil society for measures of progress that go beyond the traditional measures of GDP, as well as improved datasets allowing individuals and households to be tracked over their life course. The aim of this Handbook is to chart these developments and provide extensive surveys of many of the recent themes that have emerged in the research literature. Some of the topics addressed include poverty. relative deprivation and satisfaction, economic insecurity, social exclusion and inequality, income and social polarization, and social fractionalization and diversity. Each topic is first analyzed from a theoretical perspective, followed by detailed empirical discussion.
