Sociology, according to Parsons, is the study of the composition and behavior of social systems. It implies that sociology is the methodical study of social groups. Sociology is the study of society.
The aforementioned information leads us to the conclusion that social groups are the fundamental component of every social function, social structure, social institution, system, and organization. The study of social groups serves as the foundation for all sociological research.
This implies the significance of social groups in human existence. The significance of social groupings is made more apparent when we consider that social groups are where human personality develops.
The kind of groups a person was socialized in will determine the kind of personality they have. Social groups are involved in the entire socialization process.

Like a sponge, a person soaks up the essence of their culture from the communities they engage with. Culture is not just a mere existence, but a collective way of living - a tapestry woven together by the threads of tradition, language, and customs. And it is only through social interaction that one can unravel the intricate patterns and intricacies that make up the fabric of a people's way of life.
A man picks up his culture from the groups he associates with. Culture is a people's way of life. Only by engaging in social interactions with others can one learn the ways of life.
It implies that group interaction is a crucial component of the

Social groups give poor people what they need. In this sense, the fulfillment of wants acts as a unifying factor among individuals and brings them together as a social community. People are categorized into many categories by society based on their wants and interests.
In society, these groups play complementary roles. They support one another and meet people's needs. The individuals who work in the institutions determine how well they operate.
