Orenburg, 
Russia
426,263 people lived in Orenburg in 2025. It is the 1312th largest of the world's 12,138 cities, and the 33rd largest in Russia.
That figure counts the whole built-up area, not the area Orenburg governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Orenburg grew
Where Orenburg had 10 people in 1975, it had 9.1 in 2025, fewer than it started with.
On the UN's projection it will have 401,793 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: 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 Orenburg; 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, Orenburg covered 86 km², and buildings, roads and other built-up land covered 21 km² of it. That is 50 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown by 81%, and its people have fallen by 9%.
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 Russia
Its share of Russia
Of every 1,000 people in Russia in 2025, 3 lived in Orenburg, which is 426,263 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 Orenburg; 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 Orenburg 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 Orenburg publishes about itself: how the figures here are put together.
