Sociologists use various lenses to study aging. Functionalism examines how the elderly contribute to social stability; conflict theory analyzes the competition for resources between age groups; and symbolic interactionism focuses on how individuals construct meaning and identity as they age. Together, these perspectives provide a comprehensive understanding of the aging experience in society.

Sociological discourse often contrasts functionalism, which views stratification as necessary for societal stability, with conflict theory, which views it as a source of oppression. Some scholars attempt to bridge these views by suggesting that stratification systems may have evolved as institutional mechanisms to manage or mitigate social conflict within complex societies.

Functionalism, or structural functionalism, views society as a complex system whose parts work together to promote solidarity and stability. It likens society to a biological organism where each institution—such as family, education, and religion—performs specific functions necessary for the survival and equilibrium of the whole. This perspective focuses on how social structures contribute to the maintenance of the social order.

Functionalism views society as a complex system whose parts work together to promote stability. From this perspective, media and technology are seen as institutions that perform specific functions, such as providing information, entertainment, and social integration, which contribute to the overall smooth operation and maintenance of the social order.

The functionalist perspective views society as a complex system whose parts work together to promote stability. Ethnocentrism is seen as functional because it creates a sense of 'in-group' loyalty and solidarity, which helps maintain social cohesion and collective identity within a culture.

Robert K. Merton is widely recognized for adapting Durkheim's concept of anomie into his own strain theory. Merton argued that deviance occurs when there is a disconnect between culturally approved goals and the legitimate means available to achieve them, providing a foundational framework for understanding criminal and deviant behavior in society.

Walter Miller's Lower Class Focal Value theory suggests that delinquency is not necessarily a reaction to middle-class values, but rather the result of adherence to specific focal concerns (such as toughness, smartness, and excitement) inherent in lower-class subcultures.

Functionalists, such as Davis and Moore, argue that social inequality serves a vital function by ensuring that the most demanding and important roles in society are filled by the most qualified individuals. By offering higher rewards and status for these positions, society incentivizes talented people to undergo the necessary training, thereby maintaining the efficient operation of the social system.

Functionalists, such as Émile Durkheim, argue that deviance is not merely destructive. It serves a positive function by challenging existing norms and highlighting the need for adjustments, which ultimately drives social change. By pushing the boundaries of what is acceptable, deviant behavior can lead to the evolution of societal values and legal systems.

The functionalist perspective views society as a complex system whose parts work together to promote stability and solidarity. It posits that shared norms and values are essential for social cohesion. If large numbers of people were to reject these norms, the social order would break down, leading to instability and dysfunction within the societal structure.
