Consider the following statements regarding Population Density in India: 1. Density of population is defined as the number of persons per unit area. 2. Since Independence the Density has increased by more than 200%. 3. Hill states of the Himalayan region and the North-Eastern states of India excluding Assam have relatively low densities. Which of the above statements are correct?

The correct answer is 1, 2 and 3. Key Points Population Density: Population Density is defined as the number of persons per unit area . Hence statement 1 is correct It helps in getting a better understanding of the spatial distribution of the population in relation to land. The density of the population in India (2011) is 382 persons per sq km. Density of population increased from 117 persons/ sq km in 1951 to 382 persons/sq km in 2011 . It has i ncreased more than 200% . Hence statement 2 is correct Spatial variation of population densities in the country ranges from as low as 17 persons per sq km in Arunachal Pradesh to 11,297 persons in Delhi. Among the northern Indian States, Bihar (1102), West Bengal (1029) and Uttar Pradesh (828) have higher densities, while Kerala (859) and Tamil Nadu (555) have higher densities among the peninsular Indian states. States like Assam, Gujarat, Andhra Pradesh, Haryana, Jharkhand, Odisha have moderate densities. The hill states of the Himalayan region and the Northeastern states of India (excluding Assam) have relatively low densities. Hence statement 3 is correct While the Union Territories (excluding Andaman and Nicobar islands) have very high densities of population. The density of the population is a crude measure of the human and land relationship. To get a better insight into the human-land ratio in terms of pressure of population on total cultivable land , the physiological and the agricultural densities should be found out which are significant for a country like India having a large agricultural population.
