Which term defines a social system where members share relationships and identity within a specific location or interest group?

The term that defines a social system where members share relationships and identity within a specific location or interest group is "Community." A community typically consists of individuals who interact with one another, share common values, interests, and often have a sense of belonging to a particular geographical area or a mutual cause. This shared identity fosters social connections and collective interests among its members.

Communities can be based on various factors such as cultural heritage, shared interests (like hobbies or professions), or geographical locations (like neighborhoods). The emphasis on relationships and a common identity is what differentiates a community from other social systems, such as societies, which refer to broader collective groups, or organizations, which are more structured and goal-oriented. Networks, while also involving relationships, often lack the strong sense of shared identity that characterizes a community.
