Supaul, 
India
202,024 people lived in Supaul in 2025. It is the 2948th largest of the world's 12,138 cities, and the 484th largest in India.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Supaul's own can differ widely. What counts as a city here.

projected (after 2025) · how sure the UN is: high moderate low
How to read this: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

Where it is
How to read this: every dot is one of the 2,054 cities in India in 2025, and a dot's area is how many people live there, the biggest being New Delhi. The ringed dot in colour is Supaul; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Supaul covered 30 km², and buildings, roads and other built-up land covered 2.6 km² of it. That is 13 m² of built-up land for each person, about a square 4 by 4 metres. Since 2000, its built-up land has grown to 2.2 times its size, and its people have grown by 90%.
How to read this: pale is the whole of the city's land; the stronger square inside it is what is actually built on. The three are drawn to the same scale, so a larger square really is more land, and hatching means the year is the UN's projection rather than a count.

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 Supaul 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 Supaul publishes about itself: how the figures here are put together.
