This paper is concerned with the interlinked issues of citizenship and the structured dependency of older people within Social Gerontology. It argues that implicit in much British Social Gerontology is a strategy of advancing the wellbeing of elderly people through the extension of citizenship rights. Absence of these rights leads to poverty, exclusion and ageism being commonplace experiences of large sections of the older population. This approach draws heavily on the ideas regarding social citizenship of T. H. Marshall who has influenced much mainstream social policy in Britain since 1945. Changes to the Welfare State since 1979 have seriously questioned the validity of this approach and many of these criticisms apply to the structured dependency approach. Recent work on citizenship can help us to see how the relationship between old age and citizenship has changed and how far theory in social gerontology needs to change to take account of these new circumstances.
