Mortality rate – Death rate
Mortality means death therefore mortality rate is the death rate. The rate is calculated per 1000 of the population, typically measured per year.
So mortality rate is the number of deaths per 1000 of the population each year.

There are many factors that affect mortality rate including nutrition, healthcare, disease and age of population. In industrialised nations, approximately 90% of deaths are attributed to age-related causes.
