Infant mortality rate is defined as:

Infant mortality rate is defined as:

• A. The percentage of children who die before their first birthday within a particular area or country
• B. The rate of births per 1,000 people per year
• C. The number of mothers giving birth per month
• D. The average age of mothers at birth

Answer: (A)

Infant mortality rate measures the likelihood that an infant will die before reaching their first birthday in a given place and time. It’s usually reported as deaths per 1,000 live births, which can be thought of as the percentage of births that do not survive to their first birthday. The statement describing the percentage of children who die before their first birthday within a region or country aligns with this concept because it focuses on the survival of infants in that population, capturing the risk of infant death. The other ideas relate to how many births occur rather than how many infants die, or to the characteristics of mothers, not infant survival. So they don’t describe the measure of infant mortality.
