Groups of people


In the social sciences, a social group has been defined as two or more people who interact with one another, share similar characteristics, and collectively have a sense of unity. Other theorists disagree however, and are wary of definitions which stress the importance of interdependence or objective similarity. Instead, researchers within the social identity tradition generally define it as "a group is defined in terms of those who identify themselves as members of the group". Regardless, social groups come in a myriad of sizes and varieties. For example, a society can be viewed as a large social group.

A social group exhibits some degree of social cohesion and is more than a simple collection or aggregate of individuals, such as people waiting at a bus stop, or people waiting in a line. Characteristics shared by members of a group may include interests, values, representations, ethnic or social background, and kinship ties. Kinship ties being a social bond based on common ancestry, marriage, or adoption. In a similar vein, some researchers consider the defining characteristic of a group as social interaction. According to Dunbar's number, on average, people cannot maintain stable social relationships with more than 150 individuals.

Social psychologist Muzafer Sherif proposed to define a social unit as a number of individuals interacting with each other with respect to:

This definition is long and complex, but it is also precise. It succeeds at providing the researcher with the tools required to answer three important questions:

The attention of those who use, participate in, or study groups has focused on functioning groups, on larger organizations, or on the decisions made in these organizations. Much less attention has been paid to the more ubiquitous and universal social behaviors that do not clearly demonstrate one or more of the five necessary elements described by Sherif.
