What term refers to an individual affected by a disaster, regardless of age or background?

The term that accurately refers to an individual affected by a disaster, regardless of age or background, is "survivor." This word encompasses all individuals who are impacted by a crisis or disaster and signifies that they have endured and are continuing to navigate the consequences of such an event. It emphasizes resilience and the ongoing recovery process rather than solely focusing on vulnerability.

In contrast, the other terms are more specific or have different connotations. For instance, "victim" often implies a passive role in a negative situation and may not adequately reflect the agency and resilience of those impacted. "Responder" refers to individuals who provide aid or assistance during a crisis, and "volunteer" specifically indicates those who offer their services willingly without compensation. Therefore, "survivor" is the most inclusive and empowering term in this context.
