Female population = 22587902
Sex Ratio (S.R) = ?
We know,
Total number of males
S.R. = × 100
Total number of females
22563921
= × 100 = 99.89%
22587902
∴ The sex ratio of that place is 99.89%.
In the above example, sex ratio is calculated as 99.89%. It means that there is nearly equal
number of males and females in a place.
2.2 Consequences of Rapid Population Growth
Birth, death and migration are responsible for change of population. They affect the size of
population, density and composition of population. When the annual population growth
rate is more that 2.1 % and total fertility rate (TFR) of women is 2.1 per woman, it is regarded
as rapid increase of population. Rapid population growth seriously affects social, economic
and environmental aspects. It directly affects in the overall development of entire nation.
When there is increase in population, there is increase in number of feeding mouth. They
demand more food and shelter place. They randomly cut down forest to extend cultivable
land and place for shelter. Deforestation leads towards depletion of wildlife, degradation
of natural resources, scarcity of underground water, imbalance in environment and
occurrence of natural calamities. Similarly, extension of settlement areas leads towards
unmanaged urbanization, increase of pollution, problem of solid waste management, etc.
The increase of population creates increase in demand of several facilities like health,
education, drinking water, transportation, communication, entertainment, employment,
security, etc. Increase of population causes scarcity of all those facilities and increase of
crimes,violence as well as disturbance in peace, prosperity and harmony in the society.
The consequences of rapid population growth in various aspects of our life are described
below:
Impact of Rapid Population Growth on Socio-economic Aspects
a. Impact on Health
Health is the basic right of every individual.
People like to remain healthy and free from
diseases. Rapid increase of population has serious
impact on the health of people. With the increase
of population, there is increase in number of
patients as well. But in the ratio of increased
