Lalpur, 
Bangladesh
375,833 people lived in Lalpur in 2025. It is the 1512th largest of the world's 12,138 cities, and the 29th largest in Bangladesh.
Like every city on this site, Lalpur is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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). Lalpur 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, Lalpur covered 94 km², and buildings, roads and other built-up land covered 6.8 km² of it. That is 18 m² of built-up land for each person, about a square 4 by 4 metres. Since 1980, its built-up land has grown to 6.8 times its size, and its people have grown by 83%.
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, 2 lived in Lalpur, which is 375,833 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 Lalpur; the grey ones are everybody else, in other cities, in towns and out 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 Lalpur 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 Lalpur publishes about itself: how the figures here are put together.
