What term describes a temporary gathering of people who share a common focus of attention?

The term that best describes a temporary gathering of people who share a common focus of attention is "crowd." A crowd typically forms in response to an event or stimulus that draws individuals together momentarily, such as a concert, protest, or sports event. In these situations, while the individuals may not have ongoing relationships or a collective goal beyond the immediate context, they congregate in a shared space due to a common interest or focus.

Understanding the concept of a crowd is crucial as it emphasizes the transient and often spontaneous nature of such gatherings. Unlike a group or a team, which imply a more structured or sustained arrangement with defined roles and objectives, a crowd is characterized by its fluidity and the fact that members are primarily united by their collective attention to an external focal point or event.
