Final answer:
A group connected by common interests is typically known as a community or a special interest group. It includes at least two people who regularly interact and share a sense of aligned identity, ranging from small clubs to large organizations.
Step-by-step explanation:
A group of people connected by one or more common interests is generally referred to as a community or a special interest group. This defines any collection of at least two individuals who frequently interact and have a shared identity connected with the group. These groups emerge from and are defined by shared interests that could range from hobbies, professions, or even shared social statuses like income or education levels.
In broader terms, a group can be formed in distinct contexts, such as a family unit, which includes socially recognized groups of individuals joined by blood, marriage, or adoption, contributing to both an emotional connection and an economic unit within the society. Similarly, larger groups, like movements or organizations, unite members who may share geographical spaces or ideological beliefs, often aiming to achieve a common goal. However, as a group grows in size, the challenges in sustaining cohesion and a shared identity also increase.
Whether it's a small gathering of folk dancers or a global organization for individuals with high IQs like Mensa, the fundamental element that binds a group together is the commonality of interests and, often, the intangible rewards from the social interaction and the sense of belonging.
