Age set. In anthropology, an age set is a social category or corporate social group, consisting of people of similar age, who have a common identity, maintain close ties over a prolonged period, and together pass through a series of age-related statuses. This is in contrast to an age grade, through which people pass individually over time.
In modern Western societies, social stratification typically is distinguished as three social classes : (i) the upper class, (ii) the middle class, and (iii) the lower class; in turn, each class can be subdivided into strata, e.g. the upper-stratum, the middle-stratum, and the lower stratum.ocial mobility is the movement of individuals, social groups or categories of people between the layers or strata in a stratification system.
