Brahmanbaria, 
Bangladesh
2,914,727 people lived in Brahmanbaria in 2025. It is the 169th largest of the world's 12,138 cities, and the 4th largest in Bangladesh.
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 Brahmanbaria's own can differ widely. What counts as a city here.

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: 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 Brahmanbaria; 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, Brahmanbaria covered 911 km², and buildings, roads and other built-up land covered 39 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 9.7 times its size, and its people are 5.2 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.

Its share of Bangladesh

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Brahmanbaria 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 Brahmanbaria publishes about itself: how the figures here are put together.
