Praha
1,197,765 people lived in Prague in 2025. It is the 430th largest of the world's 12,138 cities, and the largest in Czechia, where it is the capital.
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.
In its own language: Praha.

How Prague grew
Where Prague had 10 people in 1975, it had 12.3 in 2025.
On the UN's projection it will have 1.2 million people in 2050. It passed a million people between 1975 and 1980.
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.

Prague through your family’s years
Put in the years your family were born. You’ll see how many people lived in Prague 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 12 cities in Czechia in 2025, and a dot's area is how many people live there. The ringed dot in colour is Prague; 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, Prague covered 261 km², and buildings, roads and other built-up land covered 58 km² of it. That is 48 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown by 62%, and its people have grown by 23%.
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 Czechia
Its share of Czechia
Of every 100 people in Czechia in 2025, 11 lived in Prague, which is 1.2 million people.
How to read this: 100 squares, one for every 100th person in Czechia; the coloured squares live in Prague. The grey rest live in other cities, in towns or in the countryside.

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