Fallujah, 
Iraq
359,695 people lived in Fallujah in 2025. It is the 1586th largest of the world's 12,138 cities, and the 20th largest in Iraq.
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 Fallujah'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: 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.

Fallujah through your family’s years
Put in the years your family were born. You’ll see how many people lived in Fallujah in each of those years, and when each of them turned 30.

Where it is
How to read this: every dot is one of the 88 cities in Iraq in 2025, and a dot's area is how many people live there, the biggest being Baghdad. The ringed dot in colour is Fallujah; 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, Fallujah covered 38 km², and buildings, roads and other built-up land covered 11 km² of it. That is 31 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.4 times its size, and its people are 4.1 times as many.
How to read this: pale is the whole of the city's land; the stronger square inside it is what is actually built on. The three are drawn to the same scale, so a larger square really is more land, and hatching means the year is the UN's projection rather than a count.
Of every 100 people in Iraq
Its share of Iraq
Of every 1,000 people in Iraq in 2025, 8 lived in Fallujah, which is 359,695 people.
How to read this: shrink Iraq to 1,000 people and this is what you get. The coloured squares are the ones who would live in Fallujah; 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 Fallujah 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 Fallujah publishes about itself: how the figures here are put together.
