Standard Reference VerifiedStatement 1 is incorrect: Infant Mortality Rate (IMR) measures the death of infants before reaching their first birthday (within the first full year of life), whereas deaths within the first 28 days are termed Neonatal Mortality Rate.
Statement 2 is incorrect: IMR is calculated per 1,000 live births in a given year, not per 100 live births.
