1.1 Types of Groups

Most of us feel comfortable using the word “group” without giving it much thought. But what does it mean to be part of a group? The concept of a group is central to much of how we think about society and human interaction. As Georg Simmel (1858–1915) put it, “[s]ociety exists where a number of individuals enter into interaction” (1908). Society exists in groups. For Simmel, society did not exist otherwise. What fascinated him was the way in which people mutually attune to one another to create relatively enduring forms. In a group, individuals behave differently than they would if they were alone. They conform, they resist, they forge alliances, they cooperate, they betray, they organize, they defer gratification, they show respect, they expect obedience, they share, they manipulate, etc. Being in a group changes their behaviour and their abilities. This is one of the founding insights of sociology: the whole is greater than the sum of its parts. The group has properties over and above the properties of its individual members. It has a reality sui generis, of its own kind. But how exactly does the whole come to be greater?

Defining a Group

How can we hone the meaning of the term group more precisely for sociological purposes? The term is an amorphous one and can refer to a wide variety of gatherings, from just two people (think about a “group project” in school when you partner with another student), a club, a regular gathering of friends, or people who work together or share a hobby. In short, the term refers to any collection of at least two people who interact with some frequency and who share a sense that their identity is somehow aligned with the group. Of course, every time people gather, they do not necessarily form a group. An audience assembled to watch a street performer is a one-time random gathering. Conservative-minded people who come together to vote in an election are not a group because the members do not necessarily interact with one another with some frequency. People who exist in the same place at the same time, but who do not interact or share a sense of identity—such as a bunch of people standing in line at Starbucks—are considered an  aggregate, or a crowd. People who share similar characteristics but are not otherwise tied to one another in any way are considered a category.

An example of a category would be Millennials, the term given to all children born from approximately 1980 to 2000. Why are Millennials a category and not a group? Because while some of them may share a sense of identity, they do not, as a whole, interact frequently with each other.

Interestingly, people within an aggregate or category can become a group. During disasters, people in a neighbourhood (an aggregate) who did not know each other might become friendly and depend on each other at the local shelter. After the disaster ends and the people go back to simply living near each other, the feeling of cohesiveness may last since they have all shared an experience. They might remain a group, practising emergency readiness, coordinating supplies for next time, or taking turns caring for neighbours who need extra help. Similarly, there may be many groups within a single category. Consider teachers, for example. Within this category, groups may exist like teachers’ unions, teachers who coach, or staff members who are involved with the school board.

Types of Groups

Sociologist Charles Horton Cooley (1864–1929) suggested that groups can broadly be divided into two categories: primary groups and secondary groups (Cooley 1909). According to Cooley, primary groups play the most critical role in our lives. The primary group is usually fairly small and is made up of individuals who generally engage face-to-face in long-term, emotional ways. This group serves emotional needs: expressive functions rather than pragmatic ones. The primary group is usually made up of significant others—those individuals who have the most impact on our socialization. The best example of a primary group is the family.

Secondary groups are often larger and impersonal. They may also be task focused and time limited. These groups serve an instrumental function rather than an expressive one, meaning that their role is more goal or task oriented than emotional. A classroom or office can be an example of a secondary group. Neither primary nor secondary groups are bound by strict definitions or set limits. In fact, people can move from one group to another. A graduate seminar, for example, can start as a secondary group focused on the class at hand, but as the students work together throughout their program, they may find common interests and strong ties that transform them into a primary group.

Peter Marsden (1987) refers to one’s group of close social contacts as a core discussion group. These are individuals with whom you can discuss important personal matters or with whom you choose to spend your free time. Christakis and Fowler (2009) found that the average North American had four close personal contacts. However, 12 percent of their sample had no close personal contacts of this sort, while 5 percent had more than eight close personal contacts. Half of the people listed in the core discussion group were characterized as friends, as might be expected, but the other half included family members, spouses, children, colleagues, and professional consultants of various sorts. Marsden’s original research from the 1980s showed that the size of the core discussion group decreases as one ages, there was no difference in size between men and women, and those with a post-secondary degree had core discussion groups almost twice the size of those who had not completed high school.

In-Groups and Out-Groups

One of the ways that groups can be powerful is through inclusion, and its inverse, exclusion. In-groups and out-groups are subcategories of primary and secondary groups that help identify this dynamic. Primary groups consist of both in-groups and out-groups, as do secondary groups. The feeling that one belongs in an elite or select group is a heady one, while the feeling of not being allowed in, or of being in competition with a group, can be motivating in a different way. Sociologist William Sumner (1840–1910) developed the concepts of in-group and out-group to explain this phenomenon (Sumner 1906). In short, an in-group is the group that an individual feels he or she belongs to, and believes it to be an integral part of who he or she is. An out-group, conversely, is a group someone doesn’t belong to; often there may be a feeling of disdain or competition in relation to an out-group. Sports teams, unions, and secret societies are examples of in-groups and out-groups; people may belong to, or be an outsider to, any of these.

While these affiliations can be neutral or even positive, such as the case of a team-sport competition, the concept of in-groups and out-groups can also explain some negative human behaviour, such as white supremacist movements like the Ku Klux Klan, or the bullying of gay or lesbian students. By defining others as “not like us” and inferior, in-groups can end up practicing ethnocentrism, racism, sexism, ageism, and heterosexism—manners of judging others negatively based on their culture, race, sex, age, or sexuality. Often, in-groups can form within a secondary group. For instance, a workplace can have cliques of people, from senior executives who play golf together, to engineers who write code together, to young singles who socialize after hours. While these in-groups might show favouritism and affinity for other in-group members, the overall organization may be unable or unwilling to acknowledge it. Therefore, it pays to be wary of the politics of in-groups, since members may exclude others as a form of gaining status within the group. 

Reference Groups

A reference group is a group that people compare themselves to—it provides a standard of measurement. In Canadian society, peer groups are common reference groups. Children, teens, and adults pay attention to what their peers wear, what music they like, what they do with their free time—and they compare themselves to what they see. Most people have more than one reference group, so a middle-school boy might look not only at his classmates but also at his older brother’s friends and see a different set of norms. And he might observe the antics of his favourite athletes for yet another set of behaviours.

Some other examples of reference groups can be one’s church, synagogue, or mosque; one’s cultural centre, workplace, or family gathering; and even one’s parents. Often, reference groups convey competing messages. For instance, on television and in movies, young adults often have wonderful apartments, cars, and lively social lives despite not holding a job. In music videos, young women might dance and sing in a sexually aggressive way that suggests experience beyond their years. At all ages, we use reference groups to help guide our behaviour and show us social norms. So how important is it to surround yourself with positive reference groups? You may never meet or know a reference group, but it still impacts and influences how you act. Identifying reference groups can help you understand the source of the social identities you aspire to or want to distance yourself from.
