Discuss the spatial pattern of density of population in India.

In Arunachal Pradesh the density of population is 13 persons/. sq km. In Sikkim it is 76, in Nagaland it is 120, in Mizoram 42 and 99 in western coastal regions.

The peninsular states have medium density of population except Kerala and Tamil Nadu. Maharashtra has 314 persons per sq. km, Orissa has 236 and Goa, Andhra Pradesh, Karnataka and Gujarat have 200 to 300 persons/sq. km.
The population density is less then 100 persons/sq. km. in Madhya Pradesh, Rajasthan, Uttaranchal, Chattisgarh, Nagaland, Himachal Pradesh, Manipur and Meghalaya.
