According to the 2011 Census, what was the population density of Uttar Pradesh?

Population density is the number of people living per unit of land area, calculated as Total Population ÷ Total Geographical Area, usually expressed as persons per km². It is a census statistic published state-wise for every Census of India.

Applying this to Uttar Pradesh from the 2011 Census:

1. Census 2011 recorded Uttar Pradesh's total population as 199,812,341 and its total geographical area as 240,928 km².

2. Density = Population ÷ Area = 199,812,341 ÷ 240,928 ≈ 829 persons per km², which is the figure published in the Census 2011 final tables for the state.

This figure is consistent with Uttar Pradesh's known ranking: at 829 persons per km², UP is the 4th most densely populated Indian state in the 2011 Census — behind Bihar (1,102/km²), West Bengal (1,029/km²), and Kerala (859/km²) — and well above the all-India average density of 382 persons per km², which fits UP's status as India's most populous state.
