Mariupol, 
Ukraine
375,504 people lived in Mariupol in 2025. It is the 1516th largest of the world's 12,138 cities, and the 10th largest in Ukraine.
Like every city on this site, Mariupol is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

On the UN's projection it will have 332,452 people in 2050.
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: Mariupol is the dot in colour with a ring around it. The grey dots are the other cities of Ukraine in 2025, 79 in all, led by Kiev, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Mariupol covered 127 km², and buildings, roads and other built-up land covered 33 km² of it. That is 88 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown by 23%, and its people have fallen by 20%.
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 Ukraine
Its share of Ukraine
Of every 1,000 people in Ukraine in 2025, 10 lived in Mariupol, which is 375,504 people.
How to read this: 1,000 squares stand for everyone in Ukraine, one square for every 1,000th person. Count the coloured ones and you have Mariupol's share; the grey remainder live somewhere else 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 Mariupol 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 Mariupol publishes about itself: how the figures here are put together.
