Q.What is population density? Discuss the pattern of population distribution in India.

Density and distribution together explain why some Indian states feel far more crowded than others.

Population density refers to the number of persons living per square kilometre of geographical area, calculated by dividing total population by total area. As per Census 2011, India's population density was 382 persons per sq. km, an increase from 325 persons per sq. km in 2001, reflecting continued population growth on a largely fixed land area.

Population distribution, in contrast, describes the pattern of how population is spread across different regions rather than a single average figure. In India this distribution is highly uneven: the Indo-Gangetic plains, covering states such as Uttar Pradesh, Bihar, and West Bengal, are extremely densely populated because of fertile alluvial soil, abundant water for irrigation, and a long history of urban and agricultural settlement. In contrast, hilly, desert, and forested regions — such as parts of the North-Eastern states, the Thar desert belt in Rajasthan, and hill states — have much lower density due to difficult terrain and lower agricultural potential. Urban areas across the country have also grown rapidly in population share due to migration for employment and education, even though, as per Census 2011, a majority (about 69%) of Indians still lived in rural area …

Treating density and distribution as the same concept; density is a single average number for an area, while distribution …
