Age Pyramid of expanding population is :

Options

A. Triangular shaped
B. Bell shaped
C. Urm shaped
D. None of these

Answer

### Step-by-Step Solution:

1. **Understanding Population Pyramids**:
- A population pyramid is a graphical representation that shows the distribution of various age groups in a population, typically separated by gender. It helps in visualizing the age structure of a population.

2. **Defining Expanding Population**:
- An expanding population is characterized by a higher proportion of younger individuals. This indicates that the population is growing, as there are more individuals in the younger age groups compared to older ones.

3. **Characteristics of Expansive Population Pyramid**:
- The expansive population pyramid has a broader base, which represents a larger percentage of younger age groups. This shape indicates high birth rates and a lower life expectancy.
- The pyramid typically has a triangular shape, where the width of the base is greater than the middle and top sections, signifying that there are more young people than older individuals.

4. **Shape of the Pyramid**:
- The shape of an expansive population pyramid is triangular. This is because the number of births (younger age groups) exceeds the number of deaths (older age groups), leading to a growing population.

5. **Conclusion**:
- Therefore, the age pyramid of an expanding population is triangular in shape, indicating a high fertility rate and a predominance of younger individuals.
