Rajoir, 
Bangladesh
133,428 people lived in Rajoir in 2025. It is the 4569th largest of the world's 12,138 cities, and the 101st largest in Bangladesh.
That figure counts the whole built-up area, not the area Rajoir governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

projected (after 2025) · how sure the UN is: high moderate low
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: Rajoir 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, Rajoir covered 29 km², and buildings, roads and other built-up land covered 1.7 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 70%, and its people have grown by 21%.
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.
Of every 100 people in Bangladesh
Its share of Bangladesh
Of every 1,000 people in Bangladesh in 2025, 1 lived in Rajoir, which is 133,428 people.
How to read this: 1,000 squares stand for everyone in Bangladesh, one square for every 1,000th person. Count the coloured ones and you have Rajoir's share; the grey remainder live somewhere else in the country.

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