In sociology and anthropology, social stratification is the hierarchical arrangement of individuals into social classes, castes, and divisions within a society. These hierarchies, which may be overtly or covertly present, or not present at all in some societies, are quite common in state-level societies (as distinguished from hunter-gatherer or other social arrangements).

According to Peter Robert Saunders,[1] in modern Western societies, stratification depends on social and economic classes comprising three main layers: upper class, middle class, and lower class. Each class is further subdivided into smaller classes related, in part, to occupation. The term stratification derives from the geological concept of strata, or rock layers created by natural processes

The process by which people are assigned different social ranks in society. Social stratification forms the basis of inequalities within a society: higher social ranks tend to have more power, prestige, and privilege than the lower ranks. Social stratification is based on social or biological characteristics, such as social class, age, gender, ethnic group, rather than natural ability. It is possible for a person to be assigned a high social rank with respect to one factor, such as economic status, and a lower rank with regards another factor, such as gender.
