The correct Answer is:
To solve the question regarding the characteristics of a growing population in a country, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Population Density**: - Recognize that population density is not static and can change due to various factors. In a growing population, certain age groups will dominate. 2. **Population Pyramid Analysis**: - A population pyramid is a graphical representation that shows the distribution of various age groups in a population. It typically divides the population into three main age groups: pre-reproductive, reproductive, and post-reproductive. 3. **Identifying Age Groups**: - The **pre-reproductive age group** includes children and teenagers who are not yet of reproductive age. - The **reproductive age group** consists of individuals who are capable of reproducing, typically ranging from late teens to middle age. - The **post-reproductive age group** includes older individuals who are beyond their reproductive years. 4. **Characteristics of a Growing Population**: - In a growing population, the number of individuals in the pre-reproductive age group should be greater than those in the reproductive age group. This indicates that there are many young individuals who will soon enter the reproductive age and contribute to population growth. 5. **Shape of the Population Pyramid**: - The population pyramid for a growing population will be broad at the base (indicating a larger number of young individuals) and narrow at the top (indicating fewer older individuals). This results in an upright pyramid shape. 6. **Future Implications**: - As the pre-reproductive individuals mature, they will transition into the reproductive age group, leading to an increase in birth rates and overall population density in the future. 7. **Conclusion**: - Therefore, for a country with a growing population, the correct characteristic is that the pre-reproductive individuals outnumber the reproductive individuals. ### Final Answer: The correct answer is **Option C**: In a growing population, the pre-reproductive individuals are more than the reproductive individuals.
