One of the following causes population explosion :
Updated On: Apr 17, 2024
- Decrease in death rate and increase in maternal mortality rate
- Decrease in infant mortality rate and decrease in the number of people in reproductive age
- Decrease in death rate, maternal mortality rate and infant mortality rate
- Decrease in infant mortality rate and increase in death rate
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Death rate is defined as the number of deaths per 1,000 individuals in a population per year. It decreases population size and population density. Maternal mortality rate is the rate of maternal deaths. Maternal death is the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration of pregnancy, from any cause related to or aggravated by the pregnancy or its management, but not from accidental or incidental causes.
MMR $ = \frac{\text{Maternal deaths }}{\text{Live births}}$ Infant mortality rate is the number of deaths per 1,000 infants who die between birth and 1 year of age.
A decrease in all three of these factors can result in population explosion.

Concepts Used:
Population Explosion
It refers to the rapid increase in the population of an area among human beings. Furthermore, it is a situation where the economy is not capable of coping with the increasing demand of its population. Population explosion refers to the number of people that live in an area. It is a major issue for developing countries. Also, the government is not taking proper measures to control this problem
Causes of Population Explosion:
The cause of the population explosion includes many factors and reasons. These includes:
- Increase in the birth rate
- A decrease in infant mortality rate
- The life expectancy growth
- High level of illiteracy
