Question

Increased IMR and decreased MMR in a population will
A)Cause a rapid increase in growth rate
B)Result in the decline in growth rate
C)Not cause a significant change in growth rate
D)Result in an explosive population

Answer 1

Infant mortality rate and the maternal mortality ratio both are important aspects of the population. A meaningful measure of the general health conditions and primary quality of life of the geographic region expected to be the infant mortality rate.

Complete answer:
Let us first study the options to find the correct answer:

Option A: A ratio of maternal deaths per 100,000 born over the same period in a given time is expressed as a maternal mortality ratio (MMR) and the number of people killed per 1000 births of children below a year of age is expressed as infant mortality rate (IMR) and both IMR and MMR are inversely proportional to the rate of development. Therefore, this is an incorrect answer.

Option B: As discussed above IMR and MMR are inversely proportional so if we consider one of them then there will be no change in the growth rate of the population so this is an
incorrect answer.

Option C: Increased IMR and decreased MMR in a population will not cause any significant change in the growth rate as they are inversely proportional. Therefore, this is the correct answer.

Option D: Increased IMR and decreased MMR in a population will not result in an explosive population as studied above. Therefore, this is an incorrect answer.

Hence, the correct answer is option (C)

Note: Globally in 1990, 9 million children died are younger than 1 year, and by 2015. This figure halved to 4.5 million deaths and also the IMR decreased during this same period from 64 per 1000 to 24 per 1000 live births.
