1. What could be the reasons of uneven distribution of population in India.
The reasons of uneven distribution of population in India are:
(iii) Basic Facilities such as education, health, electricity etc.
(iv) Employment opportunities
2. Table 6.1 reveals that despite the decline growth rates, the numbers of people being added every decade is steadily increasing. Why?
Increased facilities provided comfortable life to people and better medical facilities that have brought down the death rate is the cause for an increase in people being added every decade despite the decline in growth rate.
3. What could be the reasons for such (sex ratio) variations?
The reasons for such (sex ratio) variations due to:
→ Society structure: Indian society is male dominant society. The people here have remained in favour of a male child leading to female foeticide and dowry problems which make people think of female children as a burden.
→ Illiteracy: India’s literacy level is very low. They don’t have proper education and discriminate between male and female children. 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.

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 determinant of population change?
(i) The rate of population growth has been declining as a result of greater use of birth control measures.
(ii) 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. Immigration refers to the inflow of people into a region from other regions.
(iii) The age structure of a population refers to the number of people in different age groups in that population.
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.
(iv) Migration is the movement of people across regions and territories. It is a determinant factor of population change as it changes the demographics (size and composition) of both the areas of departure and arrival.
