Synthesising the social capital and ageing-friendly communities literature, this paper describes how efforts to make communities more ageing-friendly can promote social inclusion among older adults. Making existing communities more ageing-friendly involves physical and social infrastructure changes that enable older adults to pursue lifelong activities, meet their basic needs, maintain significant relationships, participate in the community in personally and socially meaningful ways, and develop new interests and sources of fulfilment. Such efforts can enhance bonding, bridging and linking capital, and thereby promote social inclusion. The authors discuss the link between ageing-friendly communities and social inclusion, and provide examples of programmes with potential to change existing communities into ones that promote the social inclusion of older adults.
