Ulan-Ude, 
Russia
262,433 people lived in Ulan-Ude in 2025. It is the 2220th largest of the world's 12,138 cities, and the 58th largest in Russia.
That figure counts the whole built-up area, not the area Ulan-Ude governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Ulan-Ude grew

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: Russia and its 254 cities in 2025, each a dot whose area is its number of people (the largest is Moscow). Ulan-Ude 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, Ulan-Ude covered 75 km², and buildings, roads and other built-up land covered 21 km² of it. That is 80 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown by 37%, and its people have fallen by 28%.
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, 2 lived in Ulan-Ude, which is 262,433 people.
How to read this: 1,000 squares stand for everyone in Russia, one square for every 1,000th person. Count the coloured ones and you have Ulan-Ude's share; the grey remainder live somewhere else 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 Ulan-Ude 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 Ulan-Ude publishes about itself: how the figures here are put together.
