Bringing together a life course and demographic perspective provides a
useful framework for studying aging. This perspective conceptualizes
aging as the dynamic process of cohorts moving through the life course
in historical time. Each cohort is embedded in a social structure tha
t regulates how it ages, and the social structure changes as the cohor
t advances through the life course over time. This view of aging provi
des a strategy for developing research on such basic questions as: Why
is the life course structured the way it is? How, and why, does the e
xperience of aging differ between cohorts? And how, and why, is aging
experienced differentially by various segments of a cohort?
