Odesa, 
Ukraine
899,157 people lived in Odesa in 2025. It is the 575th largest of the world's 12,138 cities, and the 3rd largest in Ukraine.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

How Odesa grew
Where Odesa had 10 people in 1975, it had 9.1 in 2025, fewer than it started with.
On the UN's projection it will have 825,837 people in 2050. It passed a million people between 1975 and 1980.
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: Ukraine and its 79 cities in 2025, each a dot whose area is its number of people (the largest is Kiev). Odesa 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, Odesa covered 111 km², and buildings, roads and other built-up land covered 31 km² of it. That is 34 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown by 77%, and its people have fallen by 9%.
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 Ukraine
Its share of Ukraine
Of every 100 people in Ukraine in 2025, 2 lived in Odesa, which is 899,157 people.
How to read this: 100 squares, one for every 100th person in Ukraine; the coloured squares live in Odesa. 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 Odesa 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 Odesa publishes about itself: how the figures here are put together.
