Question 2: Answer the following questions
briefly.
(i) Why is the rate of population growth in India
declining since 1981?
(ii) Discuss the major components of population
growth.
(iii) Define age structure, death rate and birth
rate.
(iv) How is migration a detrimental factor of
population change?
Answer (i): There are quite a few reasons because of
which the rate of population growth in India has been declining since 1981.
Some of the reasons are as follows:
(a) Family
planning programmes, initiated by the government have been spreading awareness
among the people about the benefits of delayed marriages for girls and also small
family norm.
(b)
Educational programmes have improved the literacy rate. This has helped more
and more people to understand the benefits of a small family. Also population
control measures taken by the Govt and several NGOs have been quite effective.
As a result
of the above, birth rates declined rapidly since 1981 which caused a decline in
the rate of population growth.
Answer (ii): The three major components of population
growth are the following -
(a) Birth Rate
The greater
the birth of children, the higher will be population growth. On the other hand,
the lesser the birth of children, the lower will be population growth.
(b) Death Rate
The higher
death rate will reduce the population growth but the lower death rate will add
to the population growth.
(c) Migration
Migration is
the movement of the people from one country to the other country. If this
process of migration is within the country, it does not bring any change in the
size of population. But migration to other countries does affect the size of
population.
Answer (iii):
Age Structure
The age
structure of a population refers to the number of people in the different age
groups in a particular country. The population of a country is composed of
children of 0-14 years, adults of 15-59 years, senior citizens aged 60 years
and above. The children and senior citizens are not producers or earners as
such they depend on the adults for their maintenance and hence they add to the
dependency ratio.
Birth
Rate and Death Rate
Birth Rate is the number of live births per thousand persons
in a year whereas Death Rate means the deaths per thousand persons in a year.
The difference between birth and death rate gives us the growth rate of
population of any country in a year.
The widening gap between the birth and death rates is
one of the main reasons for higher growth rate in India.
Answer (iv): Migration is a detrimental factor of population
change, because -
(a) During migration
people move from one region to another region. The change in population because
of this movement can be internal as well as international.
(b) International
migration changes the size of the population whereas internal migration does
not change the size of the population but influences the distribution of the
population within the nation.
(c) Migration also
changes the composition of urban and rural population in terms of the age and
sex ratios. In India the rural-urban migration has resulted in a steady
increase in the percentage of population in cities and towns.
Thus,
migration is a detrimental factor of population change as it affects the
demographics of both the areas of departure and arrival.
Question 3: Distinguish between population growth and population change.
Answer: Population
is a dynamic phenomenon. Population Growth and Population Change can be
distinguished as follows:
Population Growth
Growth of population
refers to the increase in the number of inhabitants of a country or region
during a specific period of time. Population growth can be expressed in two
ways: (1) in terms of absolute numbers, (2) in terms of percentage.
The absolute number is
the magnitude of increase which is obtained by simply subtracting the earlier
population from the later population. In terms of percentage we express the
rate of increase of population per annum which is also known as ‘annual growth
rate’.
Natural increase and immigration are the major causes for population
growth.
Population Change
Change in population
refers to the change in distribution, composition or size of a population during
a specific period of time. Some major causes of population change are - natural
increase and migration (immigration, emigration).

Question 4:
What is the relation between occupational structure and development?
Answer: The distribution of population according to the
different types of occupation is referred to as ‘Occupational Structure’.
Occupational Structure has a great impact on development. Occupations are
generally divided into four categories - primary, secondary, tertiary and
quaternary. Primary occupations include - agriculture, animal husbandry, fishing
and forestry. Secondary occupations include - primarily manufacturing
industries. Tertiary occupations include services like - doctors, teachers,
etc. while quaternary occupations include the more intellectual occupations.
The proportion of people
engaged in different activities reflects the economic development of a country.
Developed nations have a high proportion of people in secondary and tertiary
activities. Developing nations such as India, Sri Lanka etc. tend to have
higher proportion of their workforce engaged in primary activities.
Question 5:
What are the advantages of having a healthy population?
Answer: There are several advantages of having a healthy
population -
(i) Health is an
important factor of population composition which boosts the development. A
healthy person is much more efficient and productive and therefore, a healthy
population is an asset for the nation.
(ii) Absenteeism is low and
capability is high where workers are healthy.
(iii) Economic development
of a country depends on the quality, ability and efficiency of its people. So,
healthy population is the most important criterion for the prosperity and
development of any country.
Question 6:
