Tarail, 
Bangladesh
66,019 people lived in Tarail in 2025. It is the 9384th largest of the world's 12,138 cities, and the 192nd 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: Tarail 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, Tarail covered 18 km², and buildings, roads and other built-up land covered 0.9 km² of it.
How to read this: the outer pale square stands for all the land the city covers, and the solid square inside it for the part with buildings, roads and the like on it. All three squares share a scale, so you can compare them by eye. A hatched one is a year the UN has projected.

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