What is the significance of demographic transition?

The significance of demographic transition lies in its ability to illustrate how populations shift over time in relation to birth and death rates. This model outlines the stages a country goes through as it transitions from high birth and death rates to low birth and death rates, typically as part of the social and economic development process.

In the initial stages, societies usually experience high fertility and mortality rates, leading to a stable population size. As a country undergoes industrialization and improvement in healthcare, sanitation, and living conditions, both birth and death rates begin to decline. Eventually, the birth rate also falls, stabilizing the population at a lower level. Understanding these transitions helps researchers and policymakers identify patterns relating to population growth, aging, and development, which are crucial for planning resources, healthcare, and social services.

This model does not address aspects like immigration's impact on populations, predict climate scenarios, or analyze economic development directly, but rather focuses on the fundamental demographic changes that occur within a society as it evolves.
