i). Why has the rate of population growth in India declined since 1981?

Ans:  This happens because nowadays people are aware of family planning. A maximum number of steps have been taken by the government in the promotion of a family planning program.

• Growth in small or nuclear families can be seen nowadays.

• Women’s education, as well as sex education, will also help in family planning.

• Availability of contraceptives.

ii). Discuss the major components of population growth.

Ans: The major components that we come across in population growth are Birth rate, Death rate, and also migration.

• Defining the birth rate- It can be defined as the number of live births per thousand people in a year.

• As the birth rates are higher in India as compared to the death rate so it is one of the most important factors.

• Defining the death rate-It can be defined as the number of live deaths per thousand people in a year.

• Defining migration- It can be defined as the people’s movement across regions and territories.

• Migration can be of two types such as internal or external migration

• Internal migration does not affect the country but the area they will migrate to is affected as a group of individuals migrate within the country.

• Migration plays an important role as it defines the composition of the population in a country.

iii). Define age structure, death rate, and birth rate.

Ans: Age composition can be defined as the population which refers to the number of people in different age groups across the country.

• To understand the socio and economic structure according to population the different age groups people can be found in children, working-age and aged people.

• Population charts can be made according to the percentage of children, working people, and aged ones.

• Children grouped in age below fifteen, and are required food, economically unproductive, and also need all the medical care.

• Working people are grouped in the category of age fifteen to fifty-nine years, and are economically productive.

• Aged people are grouped in categories above fifty-nine which means they are economically productive but are retired.

• The natural increase in population is the difference between birth and death rate, use of birth control measures declining the population growth.

iv). How is migration a determinant factor of population change?

Ans: Defining migration- It can be defined as the people’s movement across regions and territories.

• Migration can be local and global.

• It can be seen that change in the human population is due to fertility, mortality, and migration.

• Migration flow can be more often important because the unexpected changes in the size of the population can be typically seen in migration than in fertility and mortality.

• Hence we conclude that change in statistics of the population is due to the movement of a group of people in an area permanently which results in an increase in that area.
