In sociology, what term describes groups like families and workgroups that share a close identity?

The term that best describes groups like families and workgroups that share a close identity is "in-groups." In-groups refer to the social groups to which an individual feels they belong and identify with, often characterized by shared values, beliefs, and emotional connections. This sense of belonging can foster strong bonds and a collective identity among members, which is essential for social cohesion and support within the group.

In the context of sociology, in-groups are contrasted with out-groups, which are the groups that individuals do not identify with and may even feel hostility towards. Sub-groups are smaller sections within a larger group that may share specific characteristics but do not denote the broader identity formed by the entire group. Peer groups typically refer to social groups made up of individuals of similar age, status, or interests, which are not necessarily defined by close relationships like families or workgroups. Understanding in-groups is crucial for studying how social dynamics and identities shape interactions and relationships within societies.
