To determine the correct answer regarding the population structure depicted, we need to analyze the characteristics of different population types. The options provided are: A. A young population B. An ageing population C. A stable population D. A declining population Correct Option: A. A young population Explanation of Why the Answer is Correct:

1. Definition of a Young Population: A young population is characterized by a high proportion of individuals in the younger age groups, particularly children and adolescents. This is often represented in population pyramids, where the base (younger age groups) is wider than the top (older age groups).
2. Characteristics of a Young Population:
3. High Birth Rate: Young populations typically have high birth rates, leading to a larger number of children.
4. Low Median Age: The median age of the population is low, indicating that a significant portion of the population is made up of young individuals.
5. Population Pyramid Shape: The population pyramid for a young population is usually triangular, with a broad base tapering off as age increases.
6. Implications: A young population can indicate potential for future growth, as there are many individuals entering reproductive age, which can lead to further increases in population size.

Why the Other Options are Wrong or Weaker: B. An Ageing Population: - An ageing population is characterized by a higher proportion of older individuals, often resulting from lower birth rates and higher life expectancy. The population pyramid for an ageing population would have a narrower base and a wider top, indicating more elderly individuals. This option is incorrect because it does not match the characteristics of a young population. C. A Stable Population: - A stable population has a balanced age distribution, where the birth and death rates are roughly equal, leading to little or no population growth. The population pyramid would appear more rectangular. This option is incorrect as it does not reflect the high proportion of young individuals typical of a young population. D. A Declining Population: - A declining population is characterized by a decreasing number of individuals, often due to high death rates or low birth rates. The population pyramid would show a shrinking base, indicating fewer young people. This option is incorrect because a young population would not be declining; instead, it would be growing or stable. Summary of Key Points:

• A young population has a high proportion of individuals in younger age groups, indicated by a wide base in a population pyramid.
• Characteristics include high birth rates, low median age, and potential for future growth.
• An ageing population has more older individuals, a stable population has balanced age distribution, and a declining population has fewer young people.
• Understanding population structures is crucial for planning resources, services, and policies.

Revision Summary:

• Young Population: High proportion of youth, wide base in population pyramid.
• Ageing Population: More elderly, narrow base, wider top in pyramid.
• Stable Population: Balanced age distribution, little growth.
• Declining Population: Fewer young individuals, shrinking base in pyramid.
