Crude mortality rate

Crude Mortality Rate

The Crude Mortality Rate (CMR), also known as Crude Death Rate (CDR), is a demographic measure of the number of deaths occurring in a given population over a specific period of time. It is typically expressed as deaths per 1,000 or 100,000 individuals per year.

Pronunciation

Crude: /kruːd/
Mortality: /mɔːˈtalɪti/
Rate: /reɪt/

Etymology

The term "Crude Mortality Rate" is derived from the Latin word 'crudus' meaning 'raw' or 'unrefined', and the Latin word 'mortalitas' meaning 'death'. The term 'rate' comes from the Latin 'rata' meaning 'fixed, settled'.

Definition

The Crude Mortality Rate is a basic measure of the mortality risk faced by a population. It is calculated by dividing the number of deaths in a population by the total population, and then multiplying the result by a standard value (usually 1,000 or 100,000) to make the number easier to understand and compare.

Calculation

The formula for calculating the Crude Mortality Rate is:

CMR = (Number of deaths / Total population) x 1,000
