Gdansk, 
Poland
384,985 people lived in Gdansk in 2025. It is the 1478th largest of the world's 12,138 cities, and the 7th largest in Poland.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Gdansk's own can differ widely. What counts as a city here.

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.

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

Where it is
How to read this: Gdansk is the dot in colour with a ring around it. The grey dots are the other cities of Poland in 2025, 60 in all, led by Warsaw, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Gdansk covered 106 km², and buildings, roads and other built-up land covered 20 km² of it. That is 52 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown by 72%, 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 100 people in Poland in 2025, 1 lived in Gdansk, which is 384,985 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 Gdansk; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Gdansk 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 Gdansk publishes about itself: how the figures here are put together.
