Poznan, 
Poland
494,839 people lived in Poznan in 2025. It is the 1121st largest of the world's 12,138 cities, and the 6th largest in Poland.
Like every city on this site, Poznan is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Poznan grew
Count 10 people in Poznan in 1975 and the same count gives 11.1 in 2025.
On the UN's projection it will have 452,857 people in 2050.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

Where it is
How to read this: every dot is one of the 60 cities in Poland in 2025, and a dot's area is how many people live there, the biggest being Warsaw. The ringed dot in colour is Poznan; 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, Poznan covered 147 km², and buildings, roads and other built-up land covered 31 km² of it. That is 62 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 2 times its size, and its people have grown by 11%.
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 Poland
Its share of Poland
Of every 100 people in Poland in 2025, 1 lived in Poznan, which is 494,839 people.
How to read this: shrink Poland to 100 people and this is what you get. The coloured squares are the ones who would live in Poznan; 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 Poznan 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 Poznan publishes about itself: how the figures here are put together.
