Social group

A group can be defined as two or more humans that interact with one another, accept expectations and obligations as members of the group, and share a common identity. By this definition, society can be viewed as a large group, though most social groups are considerably smaller.

Characteristics shared by members of a group may include interests, values, ethnic or social background, and kinship ties.
