social groups

In sociology, a group is usually defined as a collection of humans or animals, who share certain characteristics, interact with one another, accept expectations and obligations as members of the group, and share a common identity. Using this definition, society can appear as a large group.While an aggregate comprises merely a number of individuals, a group in sociology exhibits cohesiveness to a larger degree. Characteristics that members in the group may share include interests, values, ethnic/linguistic background, and kinship ties.
