NCERT TEXTBOOK QUESTIONS
Questions Within The Lesson
Q.1. Find out what could be the reasons of uneven
distribution of population in India.
(Page 54)
Ans. Rugged terrain and unfavourable climatic conditions are
primarily responsible for sparse population in some areas. Hilly, dissected and rocky nature
of the terrain, moderate to low rainfall, shallow and less fertile soils influence
population in hilly areas. Flat plains with fertile soils and abundant rainfall have led a large number of
people to settle in the densely populated Northern Plains.
Q.2. Table 6.1 reveals that despite the decline growth
rates, the numbers of people being added every decade is steadily increasing. Why? (Page 56)
Ans. Increased facilities provided to live a comfortable
life and better medical facilities that have brought down the death rate is the cause for increase in
people being added every decade despite the decline in growth rate.
Q.3. Find out what could be the reasons for such (sex ratio)
variations. (Page 58)
Ans. The reasons for sex ratio variations in the states of India is the social makeup of India. The people here have remained in favour of male child leading to
female foeticide and dowry problems which makes people think of female children as a
burden. In states like Kerala there are well educated people who also follow matriarchal society
rules and sex ratio in Kerala is 1058 females per 1000 males. In Haryana female child is
looked down upon and most female foeticide cases occur here. Thus it has sex ratio of 861
females per 1000 males.
Questions in the Exercise

(a) the area of departure (b) both the area of departure and
arrival
(c) the area of arrival (d) none of the above
Ans. Both the area of departure and arrival
(ii) A large proportion of children in a population is a
result of
(a) high birth rates (b) high life expectancies
(c) high death rates (d) more married couples
Ans. High birth rates
(iii) The magnitude of population growth refers to :
(a) the total population of an area
(b) the number of persons added each year
(c) the rate at which the population increases
(d) the number of females per thousand males
Ans. The total population of an area
(iv) According to the Census 2001, a literate person is one
who
(a) can read and write his/her name
(b) can read and write any language
(c) is 7 year old and can read and write any language with
understanding
(d) knows 3 Rs (reading, writing, arithmetic)
Ans. Is seven year old and can read and write any language
with understanding.
Q.2. Answer the following questions briefly.
(i) Why is the rate of population growth in India declining
since 1981?
Ans. The rate of population growth has been declining as a
result of greater use of birth control measures.
(ii) Discuss the major components of population growth.
Ans. The major components of population growth are Birth
Rate, Death Rate and Migration. The difference between birth rate and death rate accounts
for natural increase in population. Adoption of family planning measures leads to decline in
birth rate. Better availability of medical facilities leads to decrease in death rate.
Internal migration only changes the pattern of population
over different parts of the country. International migration affects both the magnitude and the
quality of population.
(iii) Define age structure, death rate and birth rate.
Ans. Birth rate is the number of live births per thousand
persons in a year. Death rate is the number of deaths per thousand persons in a year. Age structure
refers to the number of people in different age groups.
The commonly adopted age groups are Children (0-14 years), Adults (15-59 years) and Aged (60 years and
above)
(iv) How is migration a determinant of population change?
Ans. Internal migration determines population change across
regions and territories within the country. In India
there has been a significant migration from the rural areas to the cities.
Apart from magnitude, migration also brings about change in terms
of sex ratio and age composition. The migration from rural areas comprises only men. As such,
the sex ratio in village registers a decline and so does the age composition. The number of
able-bodied men in villages is reduced as a result of the rural-urban migration.
Q.3. Distinguish between population growth and population
change.
Ans. Population growth is different from population change.
Population growth is determined by the birth and death rates. Population change, on the other hand,
is determined by the birth and death rates and also by migration.
Q.4. What is the relation between occupational structure and
development?
Ans. Development is related to occupational structure of the
population. Countries are less developed where a higher percentage of population is engaged
in primary occupations like agriculture, animal husbandry, forestry and fishing.
As development takes place more people move into secondary
occupations like manufacturing.In highly developed societies, there are a high percentage
of people involved in tertiary occupations like banking, commerce, transport and
administration.
Q.5. What are the advantages of having a healthy population?
Ans. Health is an important component of population composition, which affects the process of develpment. A healthy population ensures higher productive
efficiency. Absenteeism is low where the workers are healthy.
Q.6. What are the significant features of the National
Population Policy 2000?
Ans. (i) The National Population Policy 2000 aims at
reducing infant mortal rate to below 30 per thousand live births. (ii) The policy framework provides for
imparting free and compulsory school education up to 14 years of age. (iii) Some other
areas of attention are promoting delayed marriages for girls and achieving universal
immunisation of children against all vaccine
preventable diseases. Family planning programme is to
be promoted on a voluntary basis.
