Naogaon, 
Bangladesh
338,623 people lived in Naogaon in 2025. It is the 1688th largest of the world's 12,138 cities, and the 33rd largest in Bangladesh.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Naogaon's own can differ widely. What counts as a city here.

projected (after 2025) · how sure the UN is: high moderate low
How to read this: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

Where it is
How to read this: every dot is one of the 233 cities in Bangladesh in 2025, and a dot's area is how many people live there, the biggest being Dhaka. The ringed dot in colour is Naogaon; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Naogaon covered 54 km², and buildings, roads and other built-up land covered 6.2 km² of it. That is 18 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 5.6 times its size, and its people have grown by 53%.
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.
Of every 100 people in Bangladesh
Its share of Bangladesh
Of every 1,000 people in Bangladesh in 2025, 2 lived in Naogaon, which is 338,623 people.
How to read this: 1,000 squares, one for every 1,000th person in Bangladesh; the coloured squares live in Naogaon. The grey rest live in other cities, in towns or in the countryside.

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