All age groups are included in numerator of dependency ratio except ?
**Core Concept**
The dependency ratio is a demographic measure that calculates the ratio of dependents (those who are not in the workforce, such as children and elderly people) to the working-age population. It is used to assess the economic burden of supporting dependents.
**Why the Correct Answer is Right**
The numerator of the dependency ratio includes the population below the working age (0-14 years) and the population above the working age (65 years and above). The working age population is typically defined as those between 15-64 years. The dependency ratio is calculated by dividing the sum of the population below and above the working age by the working-age population. Therefore, the correct answer includes all age groups except the working age population.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the working-age population is typically defined as those between 15-64 years, which is included in the numerator of the dependency ratio.
**Option B:** This option is incorrect because the numerator of the dependency ratio includes the population below the working age (0-14 years).
**Option C:** This option is incorrect because the numerator of the dependency ratio includes the population above the working age (65 years and above).
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the dependency ratio is a demographic measure that can have significant implications for economic planning and resource allocation.
**Correct Answer: A. The working age population.**
