Life Course Theory

Life course theory, more commonly termed the life course perspective, refers to a multidisciplinary paradigm for the study of people's lives, structural contexts, and social change. This approach encompasses ideas and observations from an array of disciplines, notably history, sociology, demography, developmental psychology, biology, and economics. In particular, it directs attention to the powerful connection between individual lives and the historical and socioeconomic context in which these lives unfold. As a concept, a life course is defined as "a sequence of socially defined events and roles that the individual enacts over time" (Giele and Elder 1998, p. 22). These events and roles do not necessarily proceed in a given sequence, but rather constitute the sum total of the person's actual experience. Thus the concept of life course implies age-differentiated social phenomena distinct from uniform life-cycle stages and the life span. Life span refers to duration of life and characteristics that are closely related to age but that vary little across time and place.

In contrast, the life course perspective elaborates the importance of time, context, process, and meaning on human development and family life (Bengtson and Allen 1993). The family is perceived as a micro social group within a macro social context—a "collection of individuals with shared history who interact within ever-changing social contexts across ever increasing time and space" (Bengston and Allen 1993, p. 470). Aging and developmental change, therefore, are continuous processes that are experienced throughout life. As such, the life course reflects the intersection of social and historical factors with personal biography and development within which the study of family life and social change can ensue (Elder 1985; Hareven 1996).
