Frankfurt, 
Germany
900,483 people lived in Frankfurt in 2025. It is the 573rd largest of the world's 12,138 cities, and the 7th largest in Germany.
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 Frankfurt's own can differ widely. What counts as a city here.

On the UN's projection it will have 873,187 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.

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

Where it is
How to read this: every dot is one of the 100 cities in Germany in 2025, and a dot's area is how many people live there, the biggest being Berlin. The ringed dot in colour is Frankfurt; 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, Frankfurt covered 192 km², and buildings, roads and other built-up land covered 45 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 by 48%, and its people have grown by 33%.
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 Germany
Its share of Germany
Of every 100 people in Germany in 2025, 1 lived in Frankfurt, which is 900,483 people.
How to read this: 100 squares stand for everyone in Germany, one square for every 100th person. Count the coloured ones and you have Frankfurt'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 Frankfurt 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 Frankfurt publishes about itself: how the figures here are put together.
