Question

what are the population pyramid ? how do they help in understanding about the population of a country

Answer 1

 A population pyramid is a graphical representation of population composition. In a population pyramid, the total population is divided into various age groups, e.g. 5 to 9 years, 10 to 14 years, etc. For each age group, the percentage of the total population is subdivided into males and females.

The relative number of children (below 15 years) and that of the elderly (above 65 years) shows the relative number of dependents in the population. The relative number of people in the working age (between 15 and 65 years) shows the relative number of productive people.

Answer 2

Answer :

A population pyramid in which the base is broad and the top part is narrow means that although a large amount of births take place, not all grow up to be adults and old; it means many die before reaching these ages. This indicates a large death rate and Kenya shows such a pyramid. This means a high population growth rate.

In countries like India, the death rate is decreasing, so the pyramid is broad in the younger age groups, and the size of the pyramid decreases steadily.
