What defines a primary group in sociology?

A primary group in sociology is characterized by being small and having intimate, personal relationships that are enduring and significant to the individuals involved. These groups are fundamental to socialization and emotional support. Members interact closely and frequently, fostering strong bonds and a deep sense of belonging and loyalty. Examples of primary groups include families, close friends, and other tightly-knit communities where interpersonal relationships are highly valued.

The other options describe different types of groups. A large, impersonal group with limited relationships represents secondary groups, where interactions are more formal and less personal. A group formed for specific economic purposes suggests an economic or instrumental affiliation, which is typically characteristic of secondary relationships as well. Finally, a temporary assembly of individuals indicates a group that lacks permanence and depth in relationships, aligning more with social gatherings or task groups rather than the intimate connections found in primary groups.
