1. Difference and Inequality: Concept and Origin of Social Stratification
Core Concept and Universal Division of Labour
No human society is completely homogeneous where all individuals and groups look alike or perform identical tasks. Even in simple societies that lack technological specialization, such as hunting and food-gathering communities, tasks are universally allocated on the basis of sex and age. The tasks that different people perform are complementary, creating distinct lifestyles and identities.
Clear Explanation: Distinguishing Difference from Inequality
Sociologists draw a fundamental distinction between the concept of difference and the concept of inequality:
- Difference: Refers to the existence of dissimilarities between objects or units. These dissimilarities are complementary and do not imply superiority, ranking, or unequal privileges. For example, men and women possess biological differences, but their complementariness forms the basis of biological reproduction. Similarly, a carpenter makes wooden tools and a weaver produces cloth; they exchange their products and depend mutually upon one another without inherent ranking.
- Inequality: Implies an unequal distribution of privileges and resources, as a consequence of which some individuals and groups are more privileged or better placed than others. Some hold control over valuable resources, resulting in an explicit ranking of people into hierarchical layers.
- Natural vs. Social Inequalities: Sociologists distinguish between natural (physical) inequalities (differences in age, health, bodily strength, and mental qualities) and social inequalities (differences in conditions of existence). Physical inequalities are small in comparison to social inequalities. While natural differences may influence individual performance within a category, social inequalities are founded on societal rules governing the distribution of power, wealth, and prestige.
The existence of difference does not necessarily imply inequality. However, the reverse is always true: inequality necessarily implies difference, and this difference becomes the social basis of inequality. Society attaches unequal social values to different qualities and tasks, ranking individuals hierarchically.
Geological Origin of the Term and Sociological Definition
The term stratification came into sociological usage in the 1940s, borrowed from the earth science of geology. Geologists explain that the earth consists of a series of superimposed layers, each layer being termed a stratum (plural: strata).
Sociologists adopted this concept to describe how human society is divided into layers placed one upon the other. However, a critical distinction exists between the geological and sociological usages:
- In geology, all rock strata forming the earth are of equal value; none is privileged over another.
- In human society, the strata are hierarchically ranked. Privileges, resources, and rewards are distributed unequally. Those occupying higher strata enjoy greater privileges, whereas those in lower strata face severe deprivations.
Central Dimensions: Power, Wealth, and Prestige
Social stratification deals specifically with systemic inequalities along three interconnected dimensions:
- Power: The degree to which individuals or groups can impose their will on others and secure obedience, even in the absence of their consent. When the exercise of power is recognized as legitimate, it is called authority.
- Wealth: Material possessions regarded as valuable in society, including land, property, buildings, livestock, money, jewelry, and capital.
- Prestige: The honour and respect associated with social positions, personal qualities, and recognized styles of life.
Is Social Stratification Universal? (Stratification vs. Inequality)
Does social stratification encompass all forms of social inequality? Sociologists clarify that social stratification is a specific type of social inequality. It refers specifically to the presence of distinct social groups ranked hierarchically with respect to power, wealth, and prestige. Members of a stratum share common sentiments, common interests, and a similar style of life.
While social inequality is found in all human societies, social stratification is not universal. In simple hunting and food-gathering bands, groups are not ranked one above another. All clans have equal access to natural resources, and there are no rich or poor social layers. Inequality exists only at the individual level based on age, gender, and personal excellence (such as the "best hunter," "best craftsman," or "best magician"). Sociologists therefore reject the older notion of "primitive communism" as absolute equality, noting that simple societies have inequalities of gender, age, and individual prestige without possessing social stratification.
Why the Concept Matters
Distinguishing difference from social inequality and understanding the geological analogy helps sociologists avoid viewing social hierarchies as natural or inevitable, demonstrating instead how societal systems create ranked layers that allocate resources and life opportunities unequally.
