Which of the following State has the lowest density of population as per the Census of 2011 ?
- (a)Himachal Pradesh
- (b)Arunachal Pradesh
- (c)West Bengal
- (d)Mizoram
Correct — B, Arunachal Pradesh. As per Census 2011, Arunachal Pradesh had a population density of only about 17 persons per sq km — the lowest of any State in India. Among the options its density is far below Mizoram (~52), Himachal Pradesh (~123) and West Bengal (~1,028), so Arunachal Pradesh has the lowest.
- (a)Himachal Pradesh — Himachal Pradesh's density was about 123 persons/sq km in 2011 — low, but several times higher than Arunachal Pradesh's.
- (c)West Bengal — West Bengal is a very densely populated State at about 1,028 persons/sq km (2011) — among India's highest, the opposite extreme from 'lowest'.
- (d)Mizoram — Mizoram's density was about 52 persons/sq km (2011) — low, but still roughly three times that of Arunachal Pradesh.
Population density = population ÷ area (persons per sq km). Census 2011: India's overall density was about 382/sq km. Arunachal Pradesh, with a large mountainous area but a small population, has the lowest State density (~17), while among the options West Bengal sits at the dense end.
The options split into sparsely populated hill / North-East States (Arunachal, Mizoram, Himachal) and a dense plains State (West Bengal). Among the sparse ones, Arunachal Pradesh — vast area, small population — is the lowest.
- Census 2011: Arunachal Pradesh ~17 persons/sq km — the lowest State density in India
- Mizoram ~52 and Himachal Pradesh ~123 persons/sq km (2011)
- West Bengal ~1,028 persons/sq km (2011) — among the densest States
- India's overall density (2011) ≈ 382 persons/sq km; Bihar highest among States (~1,106)
- Confusing lowest population (Sikkim) with lowest density (Arunachal Pradesh)
- Picking West Bengal — that is a high-density State, the opposite of what is asked
As a Census 2011 'highest / lowest' recall — memorise the extremes for density, sex ratio and literacy.
