The importance of significant family contexts that are not easily circumscribed with reference to a household or a limited set of family roles has been underlined throughout the last two decades by researchers. A strong interest for family relationships beyond the nuclear family has emerged in the social sciences. The various contributions to this book develop a configurational approach to families, which emphasizes interdependencies existing among large numbers of family members, and reconsiders some of the central issues of family life in this light: fertility projects, childcare and socialization, monetary transfers across generations and support for the elderly, relationships with grandparents, uncles, aunts and in-laws, gender inequalities, divorce and other family disruptions, and the importance of friends and acquaintances for families.
