In an age pyramid, the number of individuals of reproductive age is lesser than prereproductive but higher than post reproductive ones. The population is

Options

A. Growing
B. Declining
C. Stable
D. Can not be predicted

Answer

To solve the question regarding the characteristics of a population as described in the age pyramid, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Age Pyramid**: An age pyramid is a graphical representation of the distribution of various age groups in a population. It typically consists of three main categories: pre-reproductive (younger individuals), reproductive (individuals capable of reproduction), and post-reproductive (older individuals).

**Hint**: Recall the structure of an age pyramid and the significance of each age category.

2. **Analyzing the Given Information**: The question states that the number of individuals of reproductive age is lesser than those in the pre-reproductive age group but higher than those in the post-reproductive age group. This means:
- Pre-reproductive > Reproductive > Post-reproductive

**Hint**: Visualize the pyramid and think about how the populations in each category relate to each other.

3. **Identifying Population Types**: Based on the arrangement of individuals in the age pyramid:
- A **declining population** has more post-reproductive individuals than pre-reproductive individuals.
- A **stable population** has roughly equal numbers across all three categories.
- An **expanding population** has more individuals in the pre-reproductive age group than in the reproductive age group, and more in the reproductive age group than in the post-reproductive age group.

**Hint**: Compare the characteristics of each population type to the information given in the question.

4. **Conclusion**: Since the reproductive age group is lesser than the pre-reproductive but higher than the post-reproductive, this arrangement indicates that the population is expanding. Therefore, the correct answer is that this type of population is an **expanding population**.

**Hint**: Think about how the population dynamics would change if the reproductive age group were equal to or greater than the pre-reproductive group.

### Final Answer:
The population is an **expanding population**.
