Tomsk, 
Russia
477,632 people lived in Tomsk in 2025. It is the 1163rd largest of the world's 12,138 cities, and the 25th largest in Russia.
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 Tomsk'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: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

Where it is
How to read this: every dot is one of the 254 cities in Russia in 2025, and a dot's area is how many people live there, the biggest being Moscow. The ringed dot in colour is Tomsk; 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, Tomsk covered 78 km², and buildings, roads and other built-up land covered 18 km² of it. That is 38 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown by 52%, and its people are about 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 Russia
Its share of Russia
Of every 1,000 people in Russia in 2025, 3 lived in Tomsk, which is 477,632 people.
How to read this: shrink Russia to 1,000 people and this is what you get. The coloured squares are the ones who would live in Tomsk; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Tomsk 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 Tomsk publishes about itself: how the figures here are put together.
