A social group is a collection of two or more people who interact repeatedly, influence one another and are conscious of belonging together. Reciprocal interaction, not physical nearness, is what makes a group. C. H. Cooley (1909) identified the primary group, marked by intimate face-to-face association, such as the family. Later writers contrasted it with the secondary group, which is large, formal, impersonal and organised around a specific goal.

This note covers the meaning, characteristics and types of social groups for the UPSC Anthropology Optional. It falls under Paper I, topic 2.2 (social groups) of the Anthropology Optional syllabus.

Meaning and definition of social group

ScholarDefinition
Anderson and Parker (1966)Groups are units of two or more people meeting in the same environment, or overcoming distance by some means of communication, who are influencing each other psychologically. The distinctive bond of the group is reciprocal interaction.
MacIver and PageAny collection of human beings who are brought into social relationships with one another.
Ogburn and NimkoffWhenever two or more individuals come together and influence one another, they may be said to constitute a social group.

Friends in conversation, a committee at work and children playing together are all groups.

Group, aggregate and category

TermMeaningExample
AggregatePeople who happen to be in the same place, without lasting interactionPassengers on a bus
CategoryPeople who share a characteristic but do not interact as a unitAll persons aged 20 to 25
GroupPeople in recurrent interaction, aware of their common membershipA family; a village council

Characteristics of social groups

  • Two or more persons. A group needs at least two members.
  • Reciprocal interaction. Members influence one another; this is the distinctive bond.
  • Recurrent relations. The interaction is not temporary; it follows an organised and persistent pattern.
  • Consciousness of membership. Members are aware of one another, and this awareness shapes their behaviour and marks the group off from others.
  • Common characteristics or interests. Members share something that brings them together.
  • Stability. Because interaction recurs, groups are among the most stable units of society.
  • Functions. Groups meet the needs of their members and perform functions, such as socialisation, that society requires.

Primary group

Charles Horton Cooley introduced the concept in Social Organization (1909). He observed intimate and close relations among the members of certain small groups and called them primary groups. He defined them by "intimate face-to-face association and cooperation", emotional involvement, identification with the group and sentiments of loyalty. The family, the children's play group and the neighbourhood were his main examples.

In a primary group, feeling matters more than size. The group is the product of long, intimate and informal interaction, and the relationships are ends in themselves, not means to other ends.

Characteristics of the primary group

External characteristicsInternal characteristics
Physical proximity of membersCommon objectives
Small sizeRelations are ends in themselves
Stability and durabilityRelationships are spontaneous and personal
Continuity of relationsRelations are inclusive: the whole person is involved
 Informal control over members

Importance of the primary group

For the individualFor society
Develops personalityTransmits culture from one generation to the next
Increases efficiencyCarries the norms of society to its members
Fulfils psychological needsProvides social control and maintains order
 Ensures that social roles are performed according to norms

Secondary group

Cooley did not himself name the groups that are not primary. Later writers came to call them secondary groups, often meaning those that depend on indirect media for communication (Faris, 1937).

  • Ogburn and Nimkoff: groups which provide experience lacking in intimacy can be called secondary groups.
  • MacIver and Page: primary relations are characteristic of simple societies. As population, territory and interests grow, indirect, impersonal and utilitarian relations become necessary. They called the resulting bodies "great associations", typical of industrial and urban societies.

In a secondary group, relations are formal, impersonal, segmental and utilitarian. People deal with one another because they need each other's services, and so treat each other as means, not as ends. Only a part of the personality is involved.

Characteristics of the secondary group

CharacteristicExplanation
Secondary relations dominateRelations are impersonal, indirect, non-inclusive and contractual. Self-interest encourages individuality.
Voluntary membershipMembers are usually free to join or leave. The state is an exception, where membership is compulsory.
Large sizePhysical proximity is not required, so membership may spread across a country or the world, as in a political party, a trade union or an international association.
Goal-orientedEach arises for a specific purpose and brings together people with the same need.
Indirect communicationMembers may rarely or never meet. They rely on post, telephone, print, broadcast and social media.
Position depends on roleStanding rests on achieved status and the role performed, not on birth or ascribed status.

The distinction is not rigid

  • Secondary groups meet most of a person's needs in modern life, but they cannot replace primary groups.
  • Every large secondary group creates a network of primary groups within it, such as friendships among colleagues, which supply intimacy in impersonal settings.
  • Kingsley Davis pointed out that Cooley's "we-feeling" cannot be the distinctive mark of the primary group, since some such feeling is needed in any enduring community.
  • Between the family at one end and the army at the other lie hundreds of groups, some more primary than others. The two types are best seen as ends of a continuum.

Social groups studied by anthropologists

  • Kin groups: family, lineage, clan, phratry and moiety, recruited by descent and marriage.
  • Territorial groups: band, village and tribe, as in Elman Service's classification.
  • Age and sex groups: age-sets, age-grades and youth dormitories.
  • Associations or sodalities: non-kin groups such as secret societies and clubs.

In the small-scale societies that social anthropology first studied, almost all groups are primary, and kinship is the main principle of recruitment.

Using this topic in a UPSC answer

  • Define the group by reciprocal interaction and awareness of membership, and separate it from an aggregate.
  • Credit Cooley (1909) with the primary group and note that "secondary group" came from later writers.
  • Give the comparison table in five or six rows.
  • Add that the distinction is a continuum, citing Kingsley Davis.
  • Bring in anthropological examples: lineage and clan as primary groups; a tribal council or cooperative society as a secondary group.

Frequently asked questions

What is a social group?

A social group is two or more people who interact with one another repeatedly, influence each other, share some common interest and are aware of belonging together. Reciprocal interaction is its distinctive bond.

Who gave the concept of primary group?

C. H. Cooley gave the concept of the primary group in his book Social Organization (1909). He described it as a group marked by intimate face-to-face association and cooperation.

What is the difference between primary and secondary groups?

Primary groups are small, intimate and personal, and the relationship is an end in itself, as in the family. Secondary groups are large, formal and impersonal, and the relationship is a means to a specific goal, as in a trade union or a corporation.

What are the characteristics of a primary group?

A primary group has physical proximity, small size, stability and continuity. Its relations are personal, spontaneous and inclusive, its members share common objectives, and it exercises informal control over them.

What are examples of secondary groups?

Political parties, trade unions, corporations, professional associations and the state are examples of secondary groups. Their members are linked by a common purpose and often communicate indirectly.

What is the difference between a group and an aggregate?

An aggregate is a collection of people who happen to be together without lasting interaction, such as a crowd at a bus stop. A group has recurrent interaction and a sense of membership.

What are in-groups and out-groups?

W. G. Sumner distinguished the in-group, the "we" group to which a person belongs and feels loyal, from the out-group, the "they" group towards which the person feels indifference, rivalry or hostility.
