According to Pearson sociology is the study of human groups, structure and functions. Social groups are the building block of society. Since the conception man has been dependent upon their fellow being to gratify his basic needs. The survival of man has always been dependent on the cooperation of other fellow beings. Cooperation for survival brought the man in contact with other individuals which lead to the formation of group. However, from the above evidence we can conclude that, social group is the basic component in social function, social structure, social institutions and organizations.
In sociology the term “group” refers to the number of individuals who share similar norms, values and beliefs, who interact with each other frequently and share other similar interests. Many people living in one geographical region or just living in a similar locale will not be considered as group. The concept of group cannot be constituted without social interaction. As mentioned above frequent social interaction among the individuals is necessary for the formation of group, no matter where the individuals lives, if there is correspondence between the individuals and they share similar interests and culture then, it will come under the category of social group.

A.W Green defined social group as, an aggregate of people, who are organized, share one or more than one interest.
