Infant Mortality Rate (IMR) is calculated using live births in the denominator rather than total population because:
A. Total population data is unavailable
B. It aligns with maternal mortality calculation
C. It simplifies calculation
D. Infant deaths are directly linked to birth cohort, not total population size
Answer: Option D
Solution (By JKSSB Mock Tests)
IMR measures risk per birth event; using live births as denominator reflects the population at risk (newborns), providing a more accurate and comparable measure of infant survival than per total population.
