What demographic group consists of children under 15 years who depend on others for support?

The demographic group that consists of children under 15 years who depend on others for support is known as young dependents. This category is characterized by individuals who are typically not yet in the workforce and rely on adults, such as parents or guardians, for their care and resources. Young dependents are crucial for understanding the age structure of a population, as a higher proportion of this group can indicate future implications for educational needs and potential workforce growth.

In contrast, the other groups mentioned do not fit this definition. Old dependents refer to individuals, usually the elderly, who are often retired and may rely on support from the working-age population. The working-age population includes individuals who are actively employed or seeking employment, typically ranging from ages 15 to 64, hence not dependent on others for support in the same way that young dependents are. Senior citizens specifically refer to older individuals, usually over the age of 65, who may also have dependency needs but are not part of the young dependents category.
