Social Models of aging deal with changes over the life course. Using a loose definition of model, this paper reviews models under the following classification: Allocation models; Construction of the Life Course models; Personality and Socialization models; and Negotiation models. Differences between and within these models are explored, with particular reference to the issue of determinism and the conceptualization of social structure. The life course perspective is recognized as hegemonic in contemporary theorizing about aging, but it is seen as itself embracing diverse models.
