Density of Population

Density of Population: The density of population is the number of persons living per unit of an area. It is usually expressed as number of people per square kilometre (sq km).

`"Density of population" = "Number of people in a defined area unit"/"Total area in square km of that particular area"`

The density of the Population in India 

• The density of the population is the number of persons living per unit of an area. It is usually expressed as the number of people per square kilometre (sq km).
• According to 2011, the average population density of India is 382 persons per square kilometre. India is one of the world's ten most densely populated countries.
• Bihar is India's most densely populated state with a population density of 1,102 while Arunachal Pradesh has the least population density i.e. 17 persons per sq. km. Delhi is the most densely populated union territory, with 11,297 persons per square kilometre, while the Andaman and Nicobar Islands have the lowest population density.
• Rugged terrain and unfavourable climatic conditions are primarily responsible for states with population densities of less than 250 persons per square km. 
• Assam and the majority of Peninsular states have moderate population densities. The terrain's hilly, dissected, and rocky nature, moderate to low rainfall, shallow and less fertile soils, and low population densities have all influenced population densities in these areas.
• Because of the flat plains with fertile soils and abundant rainfall, the northern plains and Kerala in the south have high to extremely high population densities.

• The states where less than 250 persons/km.sq lives are as follows:
  1. Arunachal Pradesh
  2. Chhattisgarh
  3. Himachal Pradesh
  4. Madhya Pradesh
  5. Manipur
  6. Meghalaya
  7. Nagaland
  8. Mizoram
  9. Rajasthan
  10. Sikkim
  11. Uttarakhand
• The three states of the Northern Plains with high population densities are:
  1. Uttar Pradesh
  2. Bihar
  3. West Bengal
