The social separation of old and young: A root of ageism

Ageism has been the focus of numerous publications, while age segregation is a neglected topic. Ageism on a micro-individual level is linked to segregation on a macro level in a segregation-ageism cycle. Possible linking mechanisms, which might help break this cycle, can be found on a meso level of social networks-their structure and functions. Data from the United States and the Netherlands show that non-family networks are strongly age homogeneous. Based on earlier work by a range of scholars, we suggest that time, group identity, perspective-taking, and affective ties are factors that must be considered with regard to the functions of networks. Addressing meso level mechanisms poses challenges to social policy as well as research.
