Replacement level is the number of children a couple must produce to replace themselves so as to maintain population at zero growth lavel. The value of replacement level for developed countries is

Options

A. 2.7
B. 2.1
C. 1.9
D. 1.2

Answer

**Step-by-Step Text Solution:**

1. **Understanding Replacement Level**: The replacement level refers to the number of children a couple needs to have in order to maintain a stable population size, meaning that the population neither grows nor declines.

2. **Couple Composition**: A couple consists of two individuals. To replace themselves, they need to produce enough offspring to ensure that, on average, two children will survive to adulthood and reproduce.

3. **Ideal Replacement Level**: The ideal replacement level is typically considered to be around 2.1 children per couple in developed countries. This number accounts for factors such as infant mortality and ensures that the population remains stable.

4. **Comparison with Developing Countries**: In developing countries, the replacement level is generally higher, around 2.7 children per couple, due to higher mortality rates and other socio-economic factors.

5. **Identifying the Correct Value**: Given the options provided (2.7, 2.1, 1.9, and 1.2), the correct value for the replacement level in developed countries is 2.1.

6. **Conclusion**: Therefore, the answer to the question is that the value of the replacement level for developed countries is **2.1**.
