We propose ‘ageing in networks’ as an optic that shows how the social networks of older adults extend beyond their residential neighbourhoods to extra-local and transnational settings. The paper brings together literature on ageing and social networks in mobilities and migration research to identify shared thematic framings between non-migrant and migrant older adults. Our approach broadens the analytical frame to encapsulate how ageing individually and in communities takes place through local and international mobility and via digital technologies. Ageing in networks also illuminates the importance of connecting their social protection needs with those of the people in their care assemblages.
