Open in App
Solution
The correct option is C Not cause significant change in growth rate .
Increased IMR:
Infant mortality rate or IMR is the ratio of the number of infant deaths to the total population.
Increased IMR implies that there is an increase in the number of deaths of infants. As a result, there will be a negligible increase in births. Therefore, it will not result in population growth.
Decreased MMR:
Maternal mortality rate or MMR is the ratio of death of mothers who have given birth to a child to the total population.
Decreased MMR will not cause any significant change in growth rate of the population because the mother who survived is part of the current population.
Final answer: c. Not cause significant change in growth rate
