Kazipur, 
Bangladesh
227,234 people lived in Kazipur in 2025. It is the 2589th largest of the world's 12,138 cities, and the 55th 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: Bangladesh and its 233 cities in 2025, each a dot whose area is its number of people (the largest is Dhaka). Kazipur is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Kazipur covered 102 km², and buildings, roads and other built-up land covered 3.9 km² of it. That is 17 m² of built-up land for each person, about a square 4 by 4 metres. Since 2005, its built-up land has grown to 2.6 times its size, and its people have grown by 82%.
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 Kazipur, which is 227,234 people.
How to read this: shrink Bangladesh to 1,000 people and this is what you get. The coloured squares are the ones who would live in Kazipur; the grey ones are everybody else, in other cities, in towns and out in the country.

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 Kazipur are the UN's own, at five-year steps: an estimate for each of 2000 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 Kazipur publishes about itself: how the figures here are put together.
