mortality rate

the death rate; the ratio of the total number of deaths to the total number of the population during a specified time period. Commonly used specific mortality rates include disease, case fatality, neonatal, perinatal and preweaning mortality rates.

The rate may also be expressed as a standardized rate, when it is stated as a ratio of the expected death rate in a standard group of animals. It may also be expressed as a proportional rate, when it is stated as a proportion of all of deaths due to all causes in the group.
