The 'Population Explosion' happens in which of the following stages?

The correct answer is Second stage / Developed stage (represented in the options as "Second stageDeveloped stage").

According to the Demographic Transition Theory, the population transition of any region passes through distinct stages. Let's break down the reasons why the second stage is characterized by a "Population Explosion":

1. High Birth Rate:
In the second stage, the fertility or birth rate remains very high, as societal norms and agricultural requirements continue to favor large families, and access to family planning is still limited.

2. Rapidly Declining Death Rate:
Unlike the first stage, this stage experiences a significant reduction in the mortality (death) rate. This is primarily due to improvements in sanitation, food supply, security, transportation, and basic healthcare facilities, which dramatically reduce deaths from epidemics and starvation.

3. Large Gap (Natural Increase):
The difference between a high birth rate and a rapidly falling death rate creates a very wide gap. This difference represents the rate of natural increase. Because many more people are being born than are dying, the population grows at an extremely rapid rate, leading to the phenomenon known as a "Population Explosion".
