A peer group is a social group whose members share common characteristics such as similar interests, social position, age, and often a sense of shared identity and belonging. Peer groups play a significant role in the socialisation process, particularly during adolescence, influencing individuals' attitudes, values, behaviours, and self-concept. They provide a context for learning social skills, developing relationships, and establishing norms and expectations that may differ from those of the family or broader society. Peer influence can be strong, shaping choices related to fashion, music, activities, and even academic performance. Peer groups can provide social support and a sense of community, but they can also exert pressure to conform to group norms, sometimes in ways that may be positive or negative for the individual.
