Social structure is the recurring arrangement of institutions, positions, roles, networks, and inequalities that shapes social life. Structure becomes visible when a pattern survives the arrival and departure of particular people. Students graduate, teachers retire, and principals change, yet the school still has grade levels, schedules, credentials, authority, and funding rules. Those recurring relations form a structure.

Structure sets conditions without writing a script for every action. A bus route makes some trips easier, a credential rule opens some jobs, and a family obligation changes the cost of an evening shift. People interpret those conditions, improvise, resist, and sometimes change them. Sociology studies that meeting between patterned arrangements and agency.

Societies have changed as people developed new ways of producing food, organizing work, and coordinating large populations. Hunting-and-gathering societies generally rely on small mobile groups and flexible divisions of labor. Horticultural and pastoral societies use cultivated plants or domesticated animals. Agrarian societies organize intensive agriculture, larger settlements, political hierarchy, and surplus. Industrial societies use mechanized production and expand wage labor, cities, schools, corporations, and bureaucratic states. In a postindustrial society, service, knowledge, information, and professional work occupy a larger share of employment, though material production, farming, energy, and transport remain essential.

These categories are ideal types. Real societies combine forms. A software engineer may use cloud computing built on mined minerals, factory-made devices, electrical grids, and agricultural systems. Calling an economy postindustrial describes a shift in employment and value creation. It does not mean that physical labor has vanished. Some production may have moved to other countries, which can hide industrial dependence rather than end it.

Technology alone does not create a social type. Property, law, kinship, power, education, and culture shape how a tool is adopted. Irrigation can support shared management in one setting and concentrated control in another. A sociological explanation names the institution that turns a technical possibility into a recurring social arrangement.

Quick review: Ask what persists when the people change. A recurring position, rule, network, or institution points toward structure. Then ask how a person acts within it and what evidence would show the structure changing.
