Questions Within The Lesson
Q.1. Find out what could be the reasons of uneven distribution of population in India.
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?
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.
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.
