The casualty rate is a measure used to quantify the number of individuals who are injured or killed in a specific event, such as a war, accident, or natural disaster. It is typically expressed as a percentage or a ratio, comparing the number of casualties to the total population or the number of people involved in the event. This metric helps assess the severity and impact of the situation. Casualty rates are important for understanding the effects of conflicts, such as those involving military forces or civilian populations. They can also inform emergency response efforts and public health initiatives, guiding resources to areas most in need during crises.
