 What are population pyramids? How do they help in understanding about the population of a country?

Answer: Population pyramid is a graphical representation of population composition of a country. 

The shape of the population pyramid tells the story of the people living in that particular country. 

The numbers of children (below 15 years) are shown at the bottom and reflect the level of births. 

The size of the top shows the numbers of aged people (above 65 years) and reflects the number of deaths. 

The population pyramid also tells us how many dependents there are in a country. There are two groups of dependents — young dependents (aged below 15 years) and elderly dependents (aged over 65 years). Those of the working age are the economically active. 

The population pyramid of a country in which birth and death rates both are high is broad at the base and rapidly narrows towards the top.

‘Until the 1800s, the world’s population grew steadily but slowly.’ Why?

Answer: For an extremely long period of human history, until the 1800s, the world’s population grew steadily but slowly. Large numbers of babies were born, but they died early too. This was as there were no proper health facilities. Sufficient food was not available for all the people. Farmers were not able to produce enough to meet the food requirements of all the people. As a result the total increase in population was very low.

Discuss the population pyramid of Kenya.

he population pyramid of a country in which birth and death rates both are high is broad at the base and rapidly narrows towards the top. This is because although, many children are born, a large percentage of them die in their infancy, relatively few become adults and there are very few old people. This situation is represented by the pyramid shown for Kenya.

What does the shape of a population pyramid of India indicate?
 In countries where death rates (especially amongst the very young) are decreasing, the pyramid is broad in the younger age groups, because more infants survive to adulthood. This can be seen in the pyramid for India. Such populations contain a relatively large number of young people and which means a strong and expanding labour force.
