Fenchuganj, 
Bangladesh
161,718 people lived in Fenchuganj in 2025. It is the 3740th largest of the world's 12,138 cities, and the 88th largest in Bangladesh.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

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: Fenchuganj is the dot in colour with a ring around it. The grey dots are the other cities of Bangladesh in 2025, 233 in all, led by Dhaka, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Fenchuganj covered 55 km², and buildings, roads and other built-up land covered 2.1 km² of it. That is 13 m² of built-up land for each person, about a square 4 by 4 metres. Since 2015, its built-up land has grown by 50%, and its people have grown by 29%.
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 number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Fenchuganj are the UN's own, at five-year steps: an estimate for each of 2005 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 Fenchuganj publishes about itself: how the figures here are put together.
