Presentation of the Biographies et entourage Survey

Families extend well beyond the walls of the home, and interpersonal relations are constructed throughout the life course, and in all the settings where they play out. This approach requires new instruments of observation and new concepts to take into account family realities and their dynamics across time and space. Indeed, 20 years after the Triple biographie (Triple biography) survey and 10 years after the Proches et parents (Local family circle) survey we needed to update our knowledge of residential mobility and kinship. This chapter recounts the historical background of the Biographies et entourage survey (Event histories and contact circle survey) and presents the different INED surveys conducted from the 1960s which inspired and preceded it. By combining the relational and life course approaches, the Biographies et entourage survey was designed to obtain appropriate data for describing and analysing family networks and their role throughout an individual’s lifetime. To do that, it was necessary to move away from the usual concepts such as the household or main residence, and suggest others such as the entourage (contact circle) and the residential system
