Which term is defined as the measure of the number of deaths in a population?

The term that refers to the measure of the number of deaths in a population is mortality. Mortality is typically expressed as a rate, often calculated per a specific population size, such as deaths per 1,000 individuals, and it helps public health officials and researchers understand the health status of populations. It is a critical statistic for assessing the impact of diseases, the effectiveness of health interventions, and overall public health trends over time.

Morbidity relates to the incidence or prevalence of diseases within a population; it focuses more on illness rather than death. Demographics pertain to the statistical characteristics of human populations, such as age, race, and gender, but do not specifically address mortality. Epidemiology is the study of how diseases affect the health and illness of populations, which includes analyses of both morbidity and mortality but is broader in scope than just measuring deaths. Thus, mortality specifically captures the aspect of death within the context of public health data and statistics.
