Population explosion is the phenomenon of the size of a population tending to a very large number in a finite interval of time is called population explosion i.e., rapid increase in population for a long time may be termed as "population explosion". Birth rate is much higher than the death rate for long time may lead to population explosion. The literal meaning of population is "the whole number of people or inhabitants in a country or region". The main factors affecting the population change are the birth rate, death rate and migration. Migration is the number of people moving in (immigration) or out (emigration) of a country, place or locality. The population change is calculated by the formula: Population change = (Births + Immigration) - (Deaths + Emigration) Population explosion or overpopulation refers to a condition where an organism's numbers exceed the carrying capacity of its habitat. Every sixth person on globe today is every Indian. India adds about 10 lakh persons to its population every fortnight. India adds one Australia every eight months. By 2045 or earlier, India would overtake china as the world's most populous country. 49% of the increase in India's population is from four states Bihar, Madhya Pradesh, Rajasthan, UP.

components of population growth.

Impact of population explosion
• As population grows, it affects health and socio-
economic conditions of individual, community and
country
• Moderate population growth is considered
essential because it promotes socio-economic
developments as there is increasing demand and
market for various goods and opportunity for
employment for people.
• But when population increases faster it has its
impact on natural and men made resources and
socio-economic conditions.

1. Agriculture and economy
• India is a developing country
• About 70% people live in rural areas
• Their main source of income is agriculture several
millions of them are either marginal farmers or
worked on hired labour and struggle for bare
necessities of
• In addition, India has rapid population growth and
limited cultivation land area

• This further decrease per capita agriculture
production and causes decline in per capita
income.
• To supplement marginal income farmers, employ
their children in the farms.
• This becomes a motivational factor for having
large size family.

2. Food and nutrition
• The most direct impact of rapid population growth
is on feeding the ever-increasing large population
and on maintaining their nutritional status
• Rapid population growth is one of the factors
responsible for decreased per capita consumption
and quality of food. The most affected sections of
population are women and children.

• Only 15-20% of Indians get adequate calories
daily.
• Poor nutrition lowers the productivity of workers it
also leads to malnutrition and other nutritional
deficiency diseases such as anaemia, blindness
etc.
• So, it affects to country's level of development and
of the overall health status of its people.

3. Literacy and education
• Literacy rate has been increased gradually but the
absolute number of illiterates has been increased
because of population in creases.
• The numbers of educational institutes, universities
have increased significantly but could not keep
pace with the growing demands of increasing
population.

4. Clothing
• Next to food, clothing is basic necessity of human
beings.
• These demands are barely being met partially
because of low increase in per capita income,
poverty and large family size and partially because
of scarcity due to rapid population in spite of their
increased production.

37. Click to edit Master title style

5. Housing
• It is also basic necessity of human beings.
• There is increasing number of family members in
a family so there are no sufficient houses for the
increasing population.

supply, transport facilities but these could not meet
the demands of increasing population due to rapid

• The increasing population has created problem of
management of large quantity of waste and
maintenance of sanitation in both rural and urban

• There has been overall degradation of
environment, e.g., pollution of air, water and soil,

7. Health care services
• Since independence there has been significant
improvement in health care intra structure both in
urban and rural areas but these have been
inadequate, inaccessible and have not been able
to have optimal impact.
• Rapid increase in population has been one of the
reasons for this.

8. Employment
• Increasing population has increased magnitude of
the problem of unemployment.
• In spite of jobs being created and filled and
opportunities being provided for self-employment,
the number of unemployed as outnumbered the
employment opportunities because of ever
increasing young population due to rapid
population growth.

• Also because of low literacy and lack of technical
skills the cheap labour is made available in plenty
in labour market.
• This situation also affecting the national
productivity and per capita income.

9. Urbanization
• This low socio-economic situation also pressurizes
rural people to migrate to urban area for
employment which create socio-economic
problem in urban areas.

source of slums in big metropolitan cities.

Impact of Population Explosion on socio-
economic development of country
• As a result of high fertility and comparatively high
mortality, India has extremely large young population.
Because of huge young population dependency rate is
very high.
• Any population with percentage of dependence and
small percentage of working people will be
economically backward. With the large dependent
population, the per capita income and standard of life
cannot improve.
• Even with a remarkable increase in national income
the per capita income of Indians is still very poor, the
large population is mainly responsible for this.

Conclusion
• So rapid growth of population in our country has a
tremendous impact on our natural and manmade
resources which are already limited in comparison to
population.
• Although there have been developments in all the
resources like food, clothing, housing, education,
employment, health services etc. but could not keep
pace with demands of increasing population.
• If this situation continues, there will be vicious circle of
poverty, underdevelopment and high population which
increasing day by day, but this increase is very slow
because of rapid growth of population.
