Answer the following questions briefly.(i) Why is the rate of ... - Contemporary India

(i) Why is the rate of population growth in India declining since 1981?
The rate of population growth is declining since 1981 primarily due to the rapid decline in birth rates. This change is a result of successful family planning programs, increased social awareness, and better access to education and healthcare.

(ii) Discuss the major components of population growth.
The three major components of population growth are:

1. Birth Rate: The number of live births per thousand persons in a year.

2. Death Rate: The number of deaths per thousand persons in a year.

3. Migration: The movement of people across regions and territories, which can be internal (within the country) or international.

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

• Age Structure: It refers to the number of people in different age groups (children, working age, and the aged) in a given population.

• Birth Rate: It is the number of live births per thousand persons in a year.

• Death Rate: It is the number of deaths per thousand persons in a year.

(iv) How is migration a determinant factor of population change?
Migration is a determinant factor because:

1. It changes the size of the population in both the area of departure (out-migration) and the area of arrival (in-migration).

2. It alters the distribution of the population within a country (e.g., from rural to urban areas).

3. It changes the demographic composition, such as the age and sex ratio, of the population in both regions.
