Used to describe the relation of deaths to the population in which they occur. The mortality rate (death rate) expresses the number of deaths in a unit of population within a prescribed time and may be expressed as crude death rates (e.g., total deaths in relation to total population during a year) or as rates specific for diseases and, sometimes, for age, sex, or other attributes (e.g., number of deaths from cancer in white males in relation to the white male population during a year).
A term that applies to death. This term is usually used in the phrase “mortality rate,” which means the number of patients who died expressed as a proportion of those at risk (same as death rate).
The incidence of death in the population in a given period. The annual mortality rate is the number of registered deaths in a year, multiplied by1000 and divided by the population at the middle of the year.
Mortality signifies the state of being deceased. In the realm of statistics, it pertains to the frequency or rate at which deaths transpire within a population with respect to a specific disease or health condition.
Mortality refers to the death rate, typically expressed as the number of deaths per specific segments of the population (e.g., 100,000 or 10,000 or 1,000) annually. Often, mortality rates are determined for particular groups. As an instance, infant mortality quantifies the deaths of infants born alive within their first year of life.
Standardized mortality is a metric used to compare the death rate in specific groups, such as those based on occupation or socioeconomic status, with the death rate of the general population.
