Vital statistics are essential for calculating which of the following?
A. Literacy rate
B. Life expectancy
C. Gross Domestic Product
D. Poverty headcount ratio
Answer: Option B
Solution (By JKExamLibrary)
Life expectancy is derived from life tables constructed using age-specific death rates, which rely on vital statistics data on deaths and population by age.

Direct standardization uses the study population's age-specific death rates applied to the standard population's age structure; thus, only the study population's age-specific rates are needed.
