Work out infant mortality rate instantly with clear inputs, formula shown and shareable results.
Divides deaths under one year by live births in the same period and expresses the result per 1,000 live births.
Infant mortality rate
IMR = deaths under 1 year / live births x 1000
It is the international convention, and the denominator is births rather than the infant population so it can be compared across systems.
Not exactly, because some deaths belong to the previous birth cohort; cohort life tables correct for this.
