Question

Increased IMR and decreased MMR in a population will

• A. cause rapid increase in growth rate
• B. result in decline in growth rate
• C. not cause significant change in growth rate
• D. result in an explosive population

Answer 1

The correct option is C not cause significant change in growth rate

IMR (Infant Mortality Rate) and MMR (Maternal Mortality Rate) are responsible for affecting the growth rate. It means decline in IMR as well as MMR will result in high population growth and vice-versa.

Here, if IMR has been increased then it will result in decline in growth rate. While, decreased MMR will cause rapid increase in growth rate. Therefore, in the above situation, if IMR has been increased and MMR has been decreased in a population, it will not cause any significant change in growth rate.
