In economics, capital refers to man-made resources, such as machinery, buildings, and financial assets, that are used in the production process to generate future income or output. It is a fundamental factor of production.

In industrial societies, economic success often requires individuals to move to where jobs are located. The nuclear family is more geographically mobile than the extended family, making it better suited to the demands of a dynamic labor market. This flexibility allows workers to relocate for better opportunities, which is a key driver of economic growth and individual advancement in modern industrial economies.

Russia is the largest country by land area, spanning across Eastern Europe and Northern Asia. Its vast territory covers more than 17 million square kilometers, making it significantly larger than any other nation. This immense geographic scale encompasses diverse climates, vast natural resources, and multiple time zones, which play a crucial role in its economic and geopolitical positioning on the global stage.

A social system is a structured set of social interactions and relationships that function as a whole. It serves as a theoretical model to help sociologists understand how different parts of a community—such as institutions, roles, and norms—interconnect. By encompassing these elements, the concept allows for the analysis of how social order is maintained and how changes in one part of the system affect the entire community.

Sociological research on social mobility often suggests that individuals from smaller families have more resources invested in them, facilitating upward mobility. Conversely, coming from a very large family can sometimes be associated with fewer individual resources, making it less characteristic of the typical profile of someone achieving significant upward social advancement.

A nuclear family typically consists of two parents and their children living in a single household. In contrast, an extended family includes multiple generations or relatives beyond the immediate parents and children, such as grandparents, aunts, uncles, and cousins, often living together or maintaining close social and economic ties. Therefore, the extended family is considered the structural opposite of the nuclear family unit.

Laws are formal norms that have been codified and are enforced by the state or government authority. Unlike informal norms such as folkways or mores, which rely on social pressure for compliance, laws carry specific, institutionalized consequences for violations, ensuring a structured approach to maintaining order and justice within a legal framework.

Scientific conclusions are inherently context-dependent and subject to revision as new empirical evidence emerges. Unlike absolute dogmas, the scientific method relies on falsifiability and continuous refinement, meaning that theories are accepted only as long as they remain consistent with the best available data and observations.

Social organization is a multifaceted concept that can be analyzed at various levels, ranging from small-scale interpersonal interactions to large-scale institutional frameworks. Because it describes the patterns of relationships and the arrangement of social units, it is frequently used interchangeably with the term social structure. This flexibility allows researchers to examine how individual actions contribute to the broader stability and organization of society.

In sociology, an ecclesia is a religious organization that is integrated into the dominant culture and often functions as a state religion. It claims the membership of everyone in the society, unlike a sect or denomination which may exist alongside other groups. The term implies a formal, institutionalized relationship between the religious body and the political state structure.
