Mortality rate is the number of deaths in a group of people, usually expressed as deaths per thousand. Thus it refers to the frequency of death or the expected occurrence among a defined group of people. Hence it is also known as the death rate. It may be restricted to deaths in specific age, race, sex, or geographic groups or adjusted to suit a standard population. Therefore there are a number of different types of mortality rates depending upon the population and illness being considered.
It includes dying due to adverse environmental conditions, a disease situation or some other stress impacting the population. This word comes from mortal which in the Latin form mors which means death. It is different from the morbidity rate. Nutrition levels, standards of diet and housing, access to clean drinking water; hygiene levels, levels of infectious diseases and levels of violent crime are some of the factors that determine the mortality rate of a place.
