Question 1 of 5
1. Question
One can infer which of the following information from a population pyramid?
- Distribution of various age groups in a population
- Reproductive capabilities and likelihood of the continuation of a species
- Density of population
- Gender composition based on age groups
Select the correct answer code:
Correct
Solution: b)
A population pyramid, also called an “age-gender-pyramid“, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing. It is also used in ecology to determine the overall age distribution of a population; an indication of the reproductive capabilities and likelihood of the continuation of a species.

Question 2 of 5
2. Question
Consider the following statements.
- The fertility rate refers to the number of live births per 1000 women in the child-bearing age group, usually taken to be 15 to 49 years.
- Reaping demographic dividend due to a higher population of working-age citizens is usually the last stage in the demographic transition of any society.
Which of the above statements is/are incorrect?
Correct
Solution: b)
The fertility rate refers to the number of live births per 1000 women in the child-bearing age group, usually taken to be 15 to 49 years.
In the fourth stage, low birth rate and low death rate lead to Population stabilisation. In this stage, because of rapid economic development, standard of living of the people becomes very high.
The first stage has high fertility and high mortality because people reproduce more to compensate for the deaths due to epidemics and variable food supply.
In the second stage, birth-rate is high but death rate is low. It results in high growth rate of population.
In the third stage, a declining birth rate and low death rate lead to low population growth.

Question 3 of 5
3. Question
The term demographic trap is used by demographers to describe the combination of
- Increasing Mortality
- High Fertility rate
- Declining mortality
- Sub-replacement level fertility rates
Select the correct answer code:
Correct
Solution: c)
The term demographic trap is used by demographers “to describe the combination of high fertility (birth rates) and declining mortality (death rates) in developing countries, resulting in a period of high population growth rate (PGR).”
Sub-replacement fertility in demography refers to any fertility rate below the replacement rate that would cause the population of a certain group of people to decrease over time.

Question 4 of 5
4. Question
If men and women have equal population for all major age groups in a country, the population pyramid will tend to show
Correct
Solution: c)
The base of the pyramid represents the population of the children. If it is thick or wide, it represents that children constitute a significant part of national population. The opposite if it is narrow. So, B and D deal with the population proportions of the children and aged and therefore and incorrect in this context.
Vertical symmetry reflects the fact that all age groups contain equal numbers of males and females.

Question 5 of 5
5. Question
Malthusian trap is a situation in which
Correct
Solution: d)
Malthusian catastrophe (also known as a Malthusian trap, population trap) occurs when population growth outpaces economic growth, causing famine or war, resulting in poverty and depopulation. Such a catastrophe inevitably has the effect of forcing the population to “correct” back to a lower, more easily sustainable level.
