Louhajang, 
Bangladesh

Like every city on this site, Louhajang 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). Louhajang 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, Louhajang covered 216 km², and buildings, roads and other built-up land covered 13 km² of it. That is 18 m² of built-up land for each person, about a square 4 by 4 metres. Since 2000, its built-up land has grown to 7.1 times its size, and its people are 5.3 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.
Of every 100 people in Bangladesh
Its share of Bangladesh
Of every 1,000 people in Bangladesh in 2025, 4 lived in Louhajang, which is 725,057 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 Louhajang; 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 Louhajang 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 Louhajang publishes about itself: how the figures here are put together.
