Feni, 
Bangladesh
401,506 people lived in Feni in 2025. It is the 1409th largest of the world's 12,138 cities, and the 27th largest in Bangladesh.
Like every city on this site, Feni is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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 233 cities in Bangladesh in 2025, and a dot's area is how many people live there, the biggest being Dhaka. The ringed dot in colour is Feni; 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, Feni covered 36 km², and buildings, roads and other built-up land covered 4.5 km² of it. That is 11 m² of built-up land for each person, about a square 3 by 3 metres. Since 1975, its built-up land has grown to 4.1 times its size, and its people have grown by 74%.
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.

Its share of Bangladesh

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