Kermanshah, 
Iran
837,230 people lived in Kermanshah in 2025. It is the 629th largest of the world's 12,138 cities, and the 11th largest in Iran.
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 Kermanshah's own can differ widely. What counts as a city here.

How Kermanshah grew
Count 10 people in Kermanshah in 1975 and the same count gives 33.3 in 2025.
On the UN's projection it will have 851,759 people in 2050.
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: Iran and its 210 cities in 2025, each a dot whose area is its number of people (the largest is Tehran). Kermanshah 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, Kermanshah covered 113 km², and buildings, roads and other built-up land covered 27 km² of it. That is 32 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.6 times its size, and its people are 3.3 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 Iran
Its share of Iran
Of every 1,000 people in Iran in 2025, 9 lived in Kermanshah, which is 837,230 people.
How to read this: shrink Iran to 1,000 people and this is what you get. The coloured squares are the ones who would live in Kermanshah; 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 Kermanshah 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 Kermanshah publishes about itself: how the figures here are put together.
