Szczecin, 
Poland
300,314 people lived in Szczecin in 2025. It is the 1911th largest of the world's 12,138 cities, and the 9th largest in Poland.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

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: Poland and its 60 cities in 2025, each a dot whose area is its number of people (the largest is Warsaw). Szczecin 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, Szczecin covered 67 km², and buildings, roads and other built-up land covered 14 km² of it. That is 46 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown by 57%, 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 Poland
Its share of Poland
Of every 1,000 people in Poland in 2025, 8 lived in Szczecin, which is 300,314 people.
How to read this: 1,000 squares, one for every 1,000th person in Poland; the coloured squares live in Szczecin. The grey rest live in other cities, in towns or in the countryside.

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 Szczecin 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 Szczecin publishes about itself: how the figures here are put together.
