Which of the following statements about &;Late expanding phase&; of Demographic cycle is true
## Core Concept
The demographic transition model describes how the population of a country changes over time through four phases: pre-industrial, transitional, industrial, and post-industrial. The "late expanding phase" refers to the third stage of this model, where birth rates remain high but death rates decline significantly due to improvements in healthcare, sanitation, and possibly some increase in living standards.
## Why the Correct Answer is Right
In the late expanding phase, improvements in healthcare, nutrition, and sanitation lead to a significant decrease in mortality rates. However, birth rates remain high because traditional attitudes towards family size and children as a source of labor and social security prevail. This phase is characterized by a rapidly growing population. The statement that likely corresponds to this description would highlight significant population growth due to a gap between high birth rates and declining death rates.
## Why Each Wrong Option is Incorrect
- **Option A:** Without the specific details of option A, it's challenging to directly refute it. However, any statement contradicting the principles of demographic transition, such as a decrease in birth rates or an increase in death rates during this phase, would be incorrect.
- **Option B:** Similarly, without specifics, if option B suggests that death rates increase or that birth rates decrease significantly during the late expanding phase, it would be incorrect.
- **Option C:** If option C inaccurately describes the demographic changes, such as suggesting that the late expanding phase is characterized by low birth and death rates, it would be incorrect.
## Clinical Pearl / High-Yield Fact
A key point to remember is that countries in the late expanding phase of the demographic transition model often experience rapid population growth. This phase is critical for public health planning, as it requires increased healthcare infrastructure and resources to manage the growing population.
## Correct Answer Line
**Correct Answer: C.**
