## **Core Concept**
The young age-dependent population refers to individuals who are typically dependent on others for their care and support due to their age. This group primarily includes children and adolescents who are not yet economically independent.

## **Why the Correct Answer is Right**
The young age-dependent population generally comprises individuals under the age of 15. This age group is considered dependent because they are usually in school, not employed, and rely on adults for financial and emotional support. The exact age range can vary slightly depending on the context, but 15 is a commonly used threshold.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option suggests an age range that is too old to be considered part of the young dependent population, as it includes working-age individuals.
- **Option B:** This option suggests an even older age range, clearly including adults who are typically economically independent.
- **Option D:** This option suggests a narrower age range that might be considered part of the young dependent population but does not fully represent it.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the dependency ratio, which includes both the young and old age-dependent populations, is an important demographic measure. The young dependency ratio is calculated as the number of people aged 0-14 divided by the number of people aged 15-64, then multiplied by 100.
