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

Answer:

Population pyramids are the graphical method to show: (a) Total polulation in to male and female i.e.. sex composition. (b) Age group from 0-14, 15-59, 59 years and above. (c) Work force. (d) Dependent and productive population. The shape of the population pyramid help us to know about 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 reflect the number of deaths. The population pyramid also shows that how many dependents are there in a country.
