Question

Is it possible to achieve ‘zero population growth rate’? If yes, what kind of age pyramid is obtained?

Answer 1

1. Yes, it is possible to achieve ‘zero population growth rate.’ This occurs when the number of individuals added to a population equals the number lost through death or emigration, resulting in a constant population size without growth.
2. When zero population growth is attained, an age pyramid with an inverted bell shape is observed. In this type of pyramid, the number of individuals in the pre-reproductive age group is less, and the population sizes of both the pre-reproductive and reproductive stages are nearly equal.
3. This indicates a stable population where births and deaths are balanced, preventing population increase or decrease.
