A small group in sociology is typically defined as a group of individuals that is small enough in size for all members to interact simultaneously with one another, meaning they can engage in direct face-to-face communication, such as talking with one another or at least being personally acquainted. The size of a small group can vary, but it is usually considered to be a number where direct interaction and mutual awareness are feasible, often ranging from a dyad (two people) to a group of around 15-20 members. Small groups are characterised by closer relationships, more intimate interactions, and a greater sense of personal connection and mutual influence among members compared to larger, more formal groups. They play a crucial role in social life, providing a context for primary relationships, socialisation, and the development of social norms and identities.
