Sitamarhi, 
India
889,696 people lived in Sitamarhi in 2025. It is the 582nd largest of the world's 12,138 cities, and the 88th largest in India.
That figure counts the whole built-up area, not the area Sitamarhi governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Sitamarhi grew
Count 10 people in Sitamarhi in 1975 and the same count gives 66.8 in 2025.
On the UN's projection it will have 1.2 million people in 2050. On the UN's projection it passes a million people between 2030 and 2035.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

Where it is
How to read this: India and its 2,054 cities in 2025, each a dot whose area is its number of people (the largest is New Delhi). Sitamarhi is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Sitamarhi covered 196 km², and buildings, roads and other built-up land covered 12 km² of it. That is 13 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 9.1 times its size, and its people are 6.7 times as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in India
Its share of India
Of every 1,000 people in India in 2025, 1 lived in Sitamarhi, which is 889,696 people.
How to read this: 1,000 squares, one for every 1,000th person in India; the coloured squares live in Sitamarhi. The grey rest live in other cities, in towns or in the countryside.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Sitamarhi are the UN's own, at five-year steps: an estimate for each of 1975 to 2025, then projection to 2050. Projected years are drawn hatched, and the UN publishes no range of uncertainty for a city. What a city means here, how the UN measures one, and why that number can differ from the one Sitamarhi publishes about itself: how the figures here are put together.
