Question

In order for the human population to achieve zero population growth which of the following must occur?

• A. There must be more post reproductive individuals than reproductive individuals
• B. There must be more pre reproductive than reproductive individuals
• C. There must be the same number pre reproductive individuals as there are reproductive individuals
• D. All of these

Answer 1

The correct option is C

There must be the same number pre reproductive individuals as there are reproductive individuals

For population to be stable, i.e. the growth of population to be stable, the number of individuals in the pre-reproductive phase must be equal to number of individuals in reproductive phase. Hence, even in the coming years the number of fertile people will be same and the growth of population will be stable.
