A peer group is a social group consisting of individuals who share similar interests, age, or social status. These groups often influence each other's behaviors, attitudes, and values. Peer groups can be found in various settings, such as schools, workplaces, and communities, and they play a significant role in social development, especially during adolescence. Members of a peer group typically interact regularly and provide support, companionship, and a sense of belonging. They can also impact decision-making and identity formation. Examples of peer groups include friend circles, sports teams, and study groups, which help individuals navigate social dynamics and build relationships.
