How does a human group differ from a collectiveity or an aggregate of people?

A human group is characterized by strong interpersonal relationships, shared goals, and a sense of identity among its members, fostering cohesion and collaboration. In contrast, a collectiveity or aggregate of people may simply refer to a number of individuals gathered in a space without meaningful interaction or connection. While aggregates can exist without any social structure or purpose, a human group typically involves organized dynamics that enhance social interactions and collective outcomes.
