Social Groups and Their Types – Primary, Secondary, and Reference Groups

Download PDF 📄

In terms of Sociology, Society is made up of people who interact, share relationships, and work together. These relationships form social groups, which are the foundation of all social life. Every human being belongs to multiple groups — family, friends, workplace, political organizations, and more.
Understanding social groups helps us comprehend how individuals connect with one another, how identity is shaped, and how social order is maintained.

Meaning of Social Group

A social group is any collection of two or more individuals who interact regularly, share a sense of belonging, and have common goals or interests.
The interaction among members distinguishes a social group from a mere crowd or category.

Definitions of Social Group by Sociologists

MacIver and Page: “A social group is any collection of human beings who are brought into human relationships with one another.”
Ogburn and Nimkoff: “Whenever two or more individuals come together and influence one another, they may be said to constitute a social group.”
H.M. Johnson: “A social group is a system of social interaction.”

Key Characteristics of Social Groups

Interaction – Members communicate and influence each other.
Sense of Unity – A feeling of belonging binds members together.
Common Interests – Shared objectives or purposes.
Group Norms – Accepted rules that guide behavior.
Stability and Continuity – Groups persist over time.

Types of Social Groups

Sociologists have classified social groups in different ways. The most widely accepted classification was given by Charles Horton Cooley, who divided groups into Primary and Secondary types. Later, Robert K. Merton introduced the concept of Reference Groups.

Primary Groups

Meaning

A primary group is small, intimate, and characterized by close, face-to-face relationships. These groups play a vital role in shaping an individual’s personality, values, and emotions.

Definition (C.H. Cooley)

“By primary groups, I mean those characterized by intimate, face-to-face association and cooperation.”

Examples of Primary Social Groups

Family, peer group, neighborhood, and close friendship circles.

Characteristics

Intimate and Personal Relationships – Members know each other personally.
Emotional Attachment – Strong feelings of care, love, and loyalty.
Small Size – Limited number of members.
Permanent and Stable – Relationships last over time.
Informal Control – Behavior is regulated by social norms and emotions, not written rules.

Functions

Develops individual personality and social behavior.
Provides emotional support and security.
Acts as the first agency of socialization.
Encourages cooperation and moral values.

Example

The family is the most important primary group — it shapes the foundation of one’s social and emotional life.

Secondary Groups

Meaning

A secondary group is larger, impersonal, and goal-oriented. Relationships are based on utility, contracts, and specific roles rather than personal bonds.

Definition (Ogburn and Nimkoff)

“A secondary group is one in which the relations among members are impersonal and specialized.”

Examples of Secondary Social Groups

Workplace, trade unions, political parties, schools, or government institutions.

Characteristics

Large Size – Involves many members.
Formal Relationships – Based on written rules and defined roles.
Goal-Oriented – Formed to achieve specific objectives.
Limited Contact – Interaction is task-focused, not emotional.
Indirect Communication – Often through media, documents, or technology.

Functions

Helps in achieving economic and organizational goals.
Facilitates large-scale cooperation.
Provides opportunities for specialization and division of labor.
Promotes rational and bureaucratic functioning.

Example

An office organization or political party where members work together for a shared purpose but may not have personal ties.

Reference Groups

Meaning

A reference group is a group to which an individual compares himself or herself, whether or not they are a member of it. People use these groups as standards for self-evaluation and behavior.

Introduced by

Robert K. Merton, an American sociologist.

Examples of Reference Social Groups

A student aspiring to be like civil servants may treat UPSC officers as a reference group.
Youth influenced by celebrities or athletes.

Types (According to Merton)

Normative Reference Group – Sets ideals or values people aspire to follow.
Comparative Reference Group – Provides a benchmark for self-evaluation.

Functions

Shapes attitudes and aspirations.
Influences lifestyle and consumption patterns.
Determines social mobility and self-perception.

Conclusion
