Qom, 
Iran
815,416 people lived in Qom in 2025. It is the 644th largest of the world's 12,138 cities, and the 12th 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 Qom's own can differ widely. What counts as a city here.

How Qom grew
Where Qom had 10 people in 1975, it had 77.7 in 2025.
On the UN's projection it will have 852,654 people in 2050. It passed 250,000 people between 1980 and 1985.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: every dot is one of the 210 cities in Iran in 2025, and a dot's area is how many people live there, the biggest being Tehran. The ringed dot in colour is Qom; 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, Qom covered 101 km², and buildings, roads and other built-up land covered 33 km² of it. That is 40 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 4 times its size, and its people are 7.8 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 Qom, which is 815,416 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 Qom; 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 Qom 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 Qom publishes about itself: how the figures here are put together.
