Which of the following statements about population distribution in India are correct?

(A) Even spatial distribution of population in India is due to its close relationship with socioeconomic, physical and historical factors
(B) The coastal plains and river plains have high population concentration
(C) The urban regions draw large number of migrants causing high population concentration
(D) India has highest density of population in the world

Choose the correct answer from the options given below :

(B) and (C) only

India does not have the highest density of population in the world.

There is an uneven spatial distribution of population in India which  suggests a close relationship between population and physical, socioeconomic and historical factors. As far as the physical factors are concerned, it is clear that climate along with terrain and availability of water largely determines the pattern of the population distribution. Consequently, we observe that the North Indian Plains, deltas and Coastal Plains have higher proportion of population than the interior districts of southern and central Indian States, Himalayas, some of the north eastern and the western states. However, development of irrigation (Rajasthan), availability of mineral and energy resources (Jharkhand) and development of transport network (Peninsular States) have resulted in moderate to high concentration of population in areas which were previously very thinly populated.

The urban regions of Delhi, Mumbai, Kolkata, Bengaluru, Pune, Ahmedabad, Chennai and Jaipur have high concentration of population due to industrial development and urbanisation drawing a large numbers of rural-urban migrants.
