What is Infant Mortality Rate?

Mortality rate is a measure of the frequency of occurrence of death in a defined population during a specified interval. Infant mortality rate refers to the number of deaths of infants under one year of age per 1,000 live births in a given population. It is an important indicator of the overall health and well-being of a society, as well as the quality of healthcare and socio-economic conditions.

How is Infant Mortality Rate calculated?

The infant mortality rate or IMR for short is the number of children that die under one year of age in a given year, per 1,000 live births. Thus, infant mortality rates are calculated as the number of deaths in the first year of life divided by the number of live births, multiplied by 1000.

Infant Mortality Rate Formula

Infant Mortality Rate = deaths under 1 year / live births * 1000
