Question

The most stable population is that population where the ratio between birth rate and death rate is-

• A. More than one
• B. Equal to one
• C. Less than one
• D. None of these

Answer 1

The correct option is A More than one

In the long term, zero population growth can be achieved when the birth rate of a population equals the death rate, i.e., fertility is at replacement level and birth and death rates are stable, a condition also called demographic equilibrium, unstable rates can lead to drastic changes in population levels.

So, the correct option is 'More than one'.
