The correct answer is
the number of children who die before the age of one year as a proportion of 1000 live children born in that particular year

Infant Mortality Rate Defined

The Infant Mortality Rate (IMR) is a crucial public health indicator.

It specifically measures the number of infant deaths that occur before a child reaches the age of one year, compared to the total number of live births in a given year.

The standard calculation is expressed as deaths per 1,000 live births.

Understanding the Correct Definition

The correct definition aligns with the standard international measurement:

  • Option 2 accurately states: "the number of children who die before the age of one year as a proportion of 1000 live children born in that particular year". This is the universally accepted definition of IMR.

Why Other Options Are Incorrect

The other options define different, non-standard metrics by using incorrect age cutoffs:

  • Option 1 incorrectly uses a six-month cutoff.
  • Option 3 incorrectly uses a two-year cutoff.
  • Option 4 incorrectly uses a three-month cutoff.

These variations do not represent the standard Infant Mortality Rate (IMR).
