Final answer:
A large, unordered group of people is known as a crowd. Crowds can arise spontaneously or through scheduled events, and are influenced by social norms and collective behaviors.
Step-by-step explanation:
A large number of people collected into a close body without order is called a crowd. Crowds can form based on different situations, such as a spontaneous gathering for a limited time, or conventional crowds who come together for a regularly scheduled event like a religious service. Collective behavior and emergent norm theory explore how crowds behave and the influence of social norms within these groups.
It is generally accepted that it takes a fairly large number of people in close proximity to create what we consider a crowd. This crowd could be comprised of people who share close proximity without necessarily interacting in a purposeful way. As the size of a human population increases, so does the frequency of encountering large groups, which can lead to a variety of social dynamics.
