A country that has a stable population is characterized by an age structure that is _________________

Options

A. Largest among post-reproductive years
B. Largest among reproductive years.
C. About the same among all groups
D. Largest among pre-reductive years

Answer

To answer the question, "A country that has a stable population is characterized by an age structure that is _________________," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Population Stability**: A stable population means that the number of individuals in the population remains relatively constant over time. This implies that the birth rate and death rate are balanced.

2. **Identifying Age Groups**: In demographic studies, populations are typically divided into three main age groups:
- Pre-reproductive (young individuals who are not yet of reproductive age)
- Reproductive (individuals who are capable of reproduction)
- Post-reproductive (older individuals who are beyond reproductive age)

3. **Analyzing Age Structure in Stable Populations**: In a stable population, the proportions of individuals in these three age groups are approximately equal. This means that there are similar numbers of individuals in each age category, which helps maintain a balanced population size.

4. **Evaluating Options**: The question provides options regarding the characteristics of the age structure in a stable population:
- Option 1: Largest among post-reproductive years (incorrect)
- Option 2: Largest among reproductive years (incorrect)
- Option 3: Same among all groups (correct)

5. **Conclusion**: Therefore, the correct characterization of the age structure in a country with a stable population is that it is "same among all groups."

### Final Answer:
A country that has a stable population is characterized by an age structure that is **the same among all groups**.
