Population Explosion in Demographic Transition
Population explosion typically occurs in the second stage of the demographic transition model. This stage is characterized by high birth rates and declining death rates, leading to a rapid increase in population size.

Explanation
- Stage Two: During this stage, improvements in healthcare, sanitation, and technology lead to a decline in mortality rates, particularly infant and child mortality. However, birth rates remain high, resulting in a rapid population growth. This is often referred to as the "population explosion" phase.
- Factors contributing to population explosion: Several factors contribute to the population explosion during this stage, including increased food production, access to healthcare, and improved living conditions. These improvements lead to longer life expectancy and lower mortality rates, while birth rates remain high due to cultural, social, and economic factors.
- Impacts of population explosion: The rapid population growth experienced during this stage can put pressure on resources, infrastructure, and the environment. It can also lead to challenges such as unemployment, poverty, and food insecurity. Governments and policymakers often need to implement strategies to manage and sustain the growing population.
- Transition to later stages: As societies progress through the demographic transition model, birth rates eventually begin to decline, leading to a stabilization of the population growth. This usually occurs in the later stages of the model, where both birth and death rates are low.
In conclusion, the population explosion takes place in the second stage of the demographic transition model, characterized by high birth rates and declining death rates. This phase has significant implications for society and requires careful planning and management to ensure sustainable development.
