What is zero population and how does it effect the Earth\'s population dynamics? Explain with 150 words.

Solution

zero population is a state where population is neither increasing note decreasing. The net growth rate is 0.

Population size is determined by birth rate, death rate, immigration and emigration.

At zero population growth, we have

Birth rate + immigration = death rate + emigration

This means that sum of birth rate, that is the rate at which a woman gives birth to young ones, and immigration rate is equal to sum of death rate, that is the rate at which an individual dies and emigration.

This keeps the dynamics of earth\'s population stable. Increase in population is balanced by decrease in population. Old age population is equal to young age population.
