A crowd is a large group of people gathered in a specific place, often for a common purpose or event. Crowds can form at concerts, sports games, protests, or public celebrations. The behavior and dynamics of crowds can vary widely, influenced by factors such as the event type, location, and the emotions of the individuals involved. Crowds can be categorized into different types, such as casual crowds, which are loosely organized, and protest crowds, which are more focused and driven by a specific cause. Understanding crowd behavior is important for safety and management, especially in large gatherings where risks may arise.
