A secondary group is a larger, impersonal group formed for a specific purpose. A committee, a class, a corporation, or a political party are examples. Relationships are formal, temporary, and role-based. You interact with people as job holders, not as whole persons.

Secondary groups are essential in modern societies. They coordinate large-scale tasks that primary groups cannot. A hospital, a university, and a government agency are all secondary groups. They rely on rules, hierarchies, and written communication.

Characteristics

• Large size, often dozens or thousands of members
• Impersonal and formal relationships
• Specific goals and time limits
• Roles matter more than personalities
• Rules and contracts govern interaction

Secondary groups can feel cold. But they also offer freedom. You can leave a job or a class without losing your identity. In primary groups, exit is harder and more painful. Both types of groups are necessary. One provides intimacy. The other gets things done at scale.
