Lodz, 
Poland
582,659 people lived in Lodz in 2025. It is the 942nd largest of the world's 12,138 cities, and the 4th largest in Poland.
That figure counts the whole built-up area, not the area Lodz governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Lodz grew
Count 10 people in Lodz in 1975 and the same count gives 7.6 in 2025 — the city lost people.
On the UN's projection it will have 530,367 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: Lodz 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, Lodz covered 133 km², and buildings, roads and other built-up land covered 30 km² of it. That is 51 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown by 50%, and its people have fallen by 24%.
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, 2 lived in Lodz, which is 582,659 people.
How to read this: 100 squares, one for every 100th person in Poland; the coloured squares live in Lodz. 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 Lodz 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 Lodz publishes about itself: how the figures here are put together.
