Question

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

Answer 1

1. Yes, it is possible to achieve a ‘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 kind of pyramid, there are fewer people in the pre-reproductive age group, and the sizes of the pre-reproductive and reproductive stages are almost the same.
3. This indicates a stable population where births and deaths are balanced, preventing population increases or decreases.
