Other forms: mortalities
Mortality is the fact that living things die, or the rate at which they do. Infant mortality, mortality rate, face your own mortality.
In public health it is a measured number: the infant mortality rate is deaths under one year per thousand live births, and it is one of the most-used indicators of how well a country is doing. Excess mortality compares deaths against the expected count and was the least arguable measure during the pandemic. The other sense is philosophical: confronting your mortality. Note mortal, immortality.
