Kaliningrad, 
Russia
436,555 people lived in Kaliningrad in 2025. It is the 1278th largest of the world's 12,138 cities, and the 32nd largest in Russia.
That figure counts the whole built-up area, not the area Kaliningrad governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Kaliningrad grew
Count 10 people in Kaliningrad in 1975 and the same count gives 13.7 in 2025.
On the UN's projection it will have 432,733 people in 2050.
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.

Kaliningrad through your family’s years
Put in the years your family were born. You’ll see how many people lived in Kaliningrad in each of those years, and when each of them turned 30.

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). Kaliningrad 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, Kaliningrad covered 101 km², and buildings, roads and other built-up land covered 22 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 to 2.4 times its size, and its people have grown by 37%.
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 Kaliningrad, which is 436,555 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 Kaliningrad's share; the grey remainder live somewhere else 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 Kaliningrad 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 Kaliningrad publishes about itself: how the figures here are put together.
