Stratification Definition
Stratification refers to the hierarchical division of societies based on social characteristics, where social differences are organised along a dimension of inequality. This occurs when the relative possession or nonpossession of a characteristic, such as wealth or status, acts as the primary principle for distributing rewards within a system of unequal distribution. Members of different layers or strata often share common lifestyles and identities, which further distinguishes them from one another.
Foundations and Principles
Stratification systems are founded upon various social characteristics, including economic factors (such as social class), status markers, race, gender, birth, or age. The basis for stratification varies historically; traditional or feudal societies tended to be based primarily on status characteristics, whereas modern societies frequently emphasise economic criteria like wealth or income. Despite these historical differences, all societies exhibit a mixture of both status and economic foundations.
Theories and Functions
The importance of stratification lies in the differential access to scarce resources, as those at the top of the hierarchy possess greater access than those at the bottom. Theoretical explanations for stratification include functionalist theories, which posit that such divisions are necessary because societies require differentiation to allocate roles based on merit or qualification, ensuring that the most capable individuals undertake crucial tasks and are appropriately rewarded.
Structure and Mobility
Stratification systems can vary significantly in their rigidity. Some systems, such as those based on caste, feature rigid and impermeable boundaries with well-established mechanisms for exclusion between strata. Conversely, contemporary societies often allow for a degree of social mobility between classes. Furthermore, in complex modern societies, stratification is often multi-layered, where various bases—such as class, ethnicity, and gender—interact dynamically to define social position.
