The incidence of death is known as which term?

• A. Morbidity
• B. Mortality
• C. Lethality
• D. Fatality

Answer: (B)

Understanding death rate in a population is described by mortality. Morbidity covers illness or disease burden, not death. Lethality describes how deadly a condition is among those who have it, focusing on a specific disease’s deadliness rather than the overall population death rate. Fatality is often used for outcomes of a disease or event in a more general or case-specific sense. Since the question talks about the rate at which deaths occur in a population, the correct term is mortality.
