Question 3.
Table 6.1 reveals that despite the decline in growth rates, the number of people being added every decade is steadily increasing. Why?
The number of people are increasing every decade because India has a vary large population. When a low annual rate is applied to a very large population, it yields a large absolute increase. When more than a billion people increase even at a lower rate, the total numbers being added becomes very large. So, the number of people being added every decade is steadily increasing.

(a) the area of departure
(b) the area of arrival
(c) both the area of departure and arrival
(d) none of the above.
(c) both the area of departure and arrival

2. 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
(a) high birth rates

3. 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.
(b) the number of persons added each year

4. According to the Census a “literate” person is one who:
(a) can read and write his/her name
(b) read and write any language
(c) is above 7 years old and can read and write any language with understanding.
(d) knows the 3 ‘R’s (reading, writing, arithmetic).
(c) is above 7 years old and can read and write any language with understanding.

Question 2.
1. Why is the rate of population growth in India declining since 1981?
Since 1981, the rate of population growth in India started declining gradually because during this period, birth rate declined rapidly.

2. Discuss the major components of population growth.
The major components of population growth are as follows:
1. Birth Rate:
It is the number of live births per 1000 persons in a year. It is a major component of growth, because in India, birth rate has always been higher than death rate.

2. Death Rate:
It is the number of deaths per 1000 persons in a year. The main cause of the rate of growth of the population is the rapid decline in death rate.

3. Migration:
It is the movement of people across regions and territories. Migration can be internal or international. Internal migration does not change the size of the population, but it influences the distribution of population within the nation.

3. Define age structure, death rate and birth rate.

1. Age structure: It refers to the number of people in different age groups in a country. It is classified into three broad categories:
• Children (generally below 15 years)
• Working age (15-59 years)
• Aged (Above 59 years).
2. Death Rate: Number of deaths per 1000 persons in a year.
3. Birth Rate: Number of births per 1000 persons in a year.

4. How is migration a determinant factor of population change?
Migration means movement of people across the regions and territories. Migration can be internal or external. When internal migration takes place, it does not change the size of the population of a country but influences the density of population. This phenomenon of migration has resulted in the steady growth of population in towns and cities in India.

In India, people have migrated to the cities because of employment opportunities and better amenities. In international and external migration, people go to different countries because of higher education or employment opportunities. If this takes place in large numbers, it can affect the size of the population.

Question 3.
Distinguish between population growth and population change.
Difference between Population Growth and Population Change:

 Population Growth Population Change 1. It refers to the change in the number of inhabitants of a country/territory during a specific period of time. 1. It refers to the change in population composition. 2. It can be expressed in two ways: (a) in terms of absolute numbers (b) in terms of percentage change per year. 2.  It can be affected by three factors: (a) birth rate, (b) death rate, and (c) migration. 3. In this process, change in population size takes place. 3. In this process, change in population istribution and occupational structure takes place.

Question 4.
What is the relation between occupational structure and development?
The occupational structure refers to the distribution of the population according to different types of occupation. An economically-active percentage of population is an important index of development. Occupations are generally classified as primary, secondary and tertiary. In developed nations, a major proportion of population is engaged in secondary and tertiary activities, i.e., activities like manufacturing industry, construction, transport, communication, etc.

On the other hand, The proportion of people working in different activities reflect the economic development of a country. Developed nations have a high proportion of people in secondary and tertiary activites. In developing countries like India, a major portion of the population is engaged in primary activities like agriculture. Thus, there is a close relationship between occupational structure and development.

Question 5.
What are the advantages of having a healthy population?
The advantages of having a healthy population are as follows:

1. A healthy population can earn more, and thus, contribute more in the National Income of the country.
2. If an individual is healthy, he will definitely like to live happily and also keep others happy.
3. It improves the quality of production.
4. There is a rapid increase in economic and social development due to healthy population.
