Describe physical factors as factor for distribution of population.

Physical factors: 
(i)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.
(ii)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.
(iii)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 proportion of population in areas which were previously very thinly populated.
