The anthology "Ethnicity and Social Divisions: Contemporary Research in Sociology" is a collection of studies presented at the annual Aage Sorensen Memorial Conferences in 2006 and 2007. The volume reflects a number of important tendencies in contemporary social research: the increasing interest in questions that concern ethnicity and immigration on the one hand, the remaining centrality of social stratification and class analysis on the other hand, and the intersection between these fields. Eight young sociologists, all PhD Candidates at the universities of Harvard, Oxford or Stockholm at the time they wrote their contributions, participate in this volume. Representing a new generation of social scientists, they have conducted empirical research on social inequality related to class and ethnicity from different perspectives.
