SUBTOPIC- Population Composition
Population composition is the structure of the population with various aspects such as sex,
age, literacy level, health condition, occupation and income level.
The development of a country depends on the quality of the people that comprise the
population. The quality of the people can be determined by studying their
o age
o gender
o literacy level
o health condition
o occupation
o income level
The population structure of a country helps us determine the number of males and females,
and their age groups.
Population pyramid
Population pyramid or an age-sex pyramid is the most common method of showing the
population structure.
1. It shows the distribution of males and females in a country by their age groups.
2. The total population is divided into various groups and the percentage of the total
population is subdivided into males and females, in each of those groups.
3. The population pyramid shows
young dependents (aged below 15 years) at the bottom and reflects the level of
births
elderly dependents (aged over 65 years) at the top and reflects the level of
deaths
The working class are in the middle group and constitute the economically active
segment.
The shape of population pyramid shows the people living in that particular country.
A pyramid broad at the base indicates the percentage of young people is high while a pyramid
becoming narrow at the top indicates a high death rate.
Different countries show different patterns of population pyramids.
In Japan, low birth rates make the pyramid narrow at the base. Decreased death rates allow
numbers of people to reach old age.
India shows the pyramid which is broad at the base and thick in middle and tapper towards
end. It means India has a healthy population at middle age which shows the availability of
human resource.
