Which State ranks second in terms of population density in the North Eastern…

Population density measures how concentrated a population is in a given area. It is calculated as total population divided by geographical area, expressed as persons per square kilometre, and is reported for each Indian state from Census data. It captures settlement concentration, not a state’s total population or physical size.

Applying this to the North Eastern states using Census 2011 figures:

Ranked from highest to lowest, Assam has the highest density in the region, followed by Tripura, then Meghalaya, Manipur, Nagaland, Sikkim, Mizoram, and Arunachal Pradesh in that order. Restricting this ranking to the four states offered — Assam, Tripura, Arunachal Pradesh and Mizoram — the same order holds: Assam first, Tripura second, Mizoram third, and Arunachal Pradesh last.

As an independent check, Tripura’s Census 2011 population of about 36.74 lakh spread over roughly 10,486 square kilometres gives a density of approximately 36,74,000 divided by 10,486, which is close to 350 persons per square kilometre — matching the reported figure and confirming its position directly below Assam. Arunachal Pradesh’s much larger area of about 83,743 square kilometres relative to its small population explains its markedly lower density, ruling it out as a contender for second place.

Therefore, Tripura ranks second in population density among the North Eastern states.
