Peer group

In sociology, a peer group is both a social group and a primary group of people who have similar interests (homophily), age, background, or social status. The members of this group are likely to influence the person's beliefs and behaviour.^[1]

During adolescence, peer groups tend to face dramatic changes. Adolescents tend to spend more time with their peers and have less adult supervision. Peer groups give a sense of security and identity. A study found that during the adolescent phase as adolescents spend double time with their peers compared to the time youth spend with their parents.^[2] Adolescents' communication shifts during this time as well. They prefer to talk about school and their careers with their parents, and they enjoy talking about sex and other interpersonal relationships with their peers.^[3] Children look to join peer groups who accept them, even if the group is involved in negative activities. Children are less likely to accept those who are different from them.^[3] Friendship and support is important for people to have an active social life. Similarly, it is equally important to people with disability as it can help them to feel included, valued and happier.^[4] Social interaction among peers may influence development; quality of life outcomes. This interaction and positive relationship benefit subjective wellbeing and have a positive effect on mental and physical health.^[5]

Cliques are small groups typically defined by common interests or by friendship. Cliques typically have 2–12 members and tend to be formed by age, gender, race, and social class. Clique members are usually the same in terms of academics and risk behaviors.^[3] Cliques can serve as an agent of socialization and social control.^[6] Being part of a clique can be advantageous since it may provide a sense of autonomy, a secure social environment, and overall well-being.

Crowds are larger, more vaguely defined groups that may not have a friendship base.^[7] Crowds serve as peer groups, and they increase in importance during early adolescence, and decrease by late adolescence.^[3] The level of involvement in adult institutions and peer culture describes crowds.
