In the social sciences, social structure is the aggregate of patterned social arrangements in society that are both emergent from and determinant of the actions of individuals. Likewise, society is believed to be grouped into structurally related groups or sets of roles, with different functions, meanings, or purposes. Examples of social structure include family, religion, law, economy, and class. It contrasts with "social system", which refers to the parent structure in which these various structures are embedded. Thus, social structures significantly influence larger systems, such as economic systems, legal systems, political systems, cultural systems, etc. Social structure can also be said to be the framework upon which a society is established. It determines the norms and patterns of relations between the various institutions of the society.
Since the 1920s, the term has been in general use in social science, especially as a variable whose sub-components needed to be distinguished in relationship to other sociological variables, as well as in academic literature, as result of the rising influence of structuralism. The concept of "social stratification", for instance, uses the idea of social structure to explain that most societies are separated into different strata (levels), guided (if only partially) by the underlying structures in the social system. There are three conditions for a social class to be steady, that of class cohesiveness, the self-consciousness of classes, and the self-awareness of one's own class. It is also important in the modern study of organizations, as an organization's structure may determine its flexibility, capacity to change, and success. In this sense, structure is an important issue for management.
