Appeared in: Raj. CHO -2025

Explanation

Life expectancy at birth is calculated using age-specific mortality rates.
It reflects the average number of years a newborn is expected to live based on current mortality patterns.

It is a standard global health indicator for comparing population health.

Option B: Sex ratio measures the number of females per 1,000 males and does not use mortality statistics.
Option C: Dependency ratio is based on the proportion of dependents to the working-age population and does not require mortality data.
Option D: Population size is a simple count of people and does not involve mortality statistics.

Recall the definition and calculation method for each indicator.
Eliminate options that do not require mortality data (sex ratio, dependency ratio, population size).
Select the indicator that directly depends on mortality statistics (life expectancy at birth).
Apply this elimination and recall strategy to similar questions on health indicators.
