Positive growth rapid increase in the population is indicated by

Options

A. less number of young ones
B. large number of young ones
C. large number of old ones
D. large number of child birth

Answer

To determine what indicates a positive growth or rapid increase in a population, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Population Growth Types**:
- There are three main types of population growth: Expanding, Stable, and Declining.
- Expanding indicates positive growth, Stable indicates no growth (0), and Declining indicates negative growth.

2. **Identify Characteristics of Expanding Population**:
- In an expanding population, the pre-reproductive age group (individuals who are not yet mature enough to reproduce) is larger than the reproductive and post-reproductive age groups.
- This means that there are more individuals in the age group that can reproduce, leading to more births.

3. **Analyze Age Group Distribution**:
- If the pre-reproductive age group is high, it suggests that there will be a larger number of young individuals entering the reproductive age in the future.
- Conversely, in a stable population, the numbers in each age group remain relatively constant, and in a declining population, the pre-reproductive age group is smaller than the post-reproductive age group.

4. **Conclusion**:
- Therefore, a positive growth rate or rapid increase in the population is indicated by a larger pre-reproductive age group compared to the other age groups.

### Final Answer:
Positive growth or rapid increase in the population is indicated by a larger pre-reproductive age group.
