- Arunachal Pradesh – lowest density = 17 persons per sq. km.
- States with density below 250 persons per sq. km: Sparse population due to rugged terrain and unfavourable climate.
- Assam + most of the Peninsular states – moderate densities.
a. Reasons: hilly, dissected, rocky terrain; moderate/low rainfall; shallow and less fertile soils. - Northern Plains + Kerala (South) – high to very high densities.
a. Reasons: flat plains, fertile soils, abundant rainfall. - Three states of the Northern Plains with high population density (to be identified by students, but from map/study: Bihar, Uttar Pradesh, West Bengal).
