Abstract: | Social network analysis has grown tremendously across a wide range of disciplines and is now regarded as a road‐map in strengthening links with the life‐course perspective. ‘Linked lives’ is often cited as a key principle of life‐course theory, but there is still much to be learned about the significance of these links for the life course. Network theory refines our understanding of the properties of these links, their emergence as structures in daily life, and the mechanisms underlying the inequalities that arise from social relationships. This paper clarifies why networks can be conceptualised as meso‐level structures that bridge the micro‐macro gap. It thus addresses four processes of particular interest for the integration of life‐course and network research: (a) the problem of tie formation; (b) the activation of ties as social capital; (c) their resilience through segments of a life course; and finally, (d) the problem of their loss. In so doing, we highlight innovative approaches for each of these issues in order to propose a research agenda we call ‘Networked Lives’, which emphasises promising avenues for advancing the integration of these two important fields in the social sciences. |
