The ABC of demographic behaviour: how the interplays of alleles, brains, and contexts over the life course should shape research aimed at understanding population processes.
This paper proposes core innovations in the strategy of research on demographic behaviour. One aim is a shift of attention away from events and towards a focus on dynamic processes and their interplay: away from a preoccupation with marriage and divorce, births, deaths, migrations, and household structure towards a broader perspective that takes account of partnership and intimacy, parenthood, potential and well-being, position in society and space, and personal ties. Another aim is a much closer engagement with genetics, neuroscience, psychology, and behavioural economics. A third aim is a strategy that pays more attention to pathways within the individual, to the processes entailed when the individual interacts with various contexts, and to progressions that involve the interplay of the pathways and processes through the life course. These shifts of emphasis, which have already begun to occur, require a systematic reassessment of priorities for research on demographic behaviour.
