Curitiba, 
Brazil
2,475,352 people lived in Curitiba in 2025. It is the 200th largest of the world's 12,138 cities, and the 7th largest in Brazil.
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 Curitiba's own can differ widely. What counts as a city here.

How Curitiba grew
For every 10 people in Curitiba in 1975, there were 35.2 in 2025.
On the UN's projection it will have 2.4 million people in 2050. It passed a million people between 1975 and 1980.

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: Curitiba is the dot in colour with a ring around it. The grey dots are the other cities of Brazil in 2025, 356 in all, led by São Paulo, 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, Curitiba covered 553 km², and buildings, roads and other built-up land covered 167 km² of it. That is 67 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 2.1 times its size, and its people are 3.5 times 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 Brazil
Its share of Brazil
Of every 100 people in Brazil in 2025, 1 lived in Curitiba, which is 2.5 million people.
How to read this: 100 squares, one for every 100th person in Brazil; the coloured squares live in Curitiba. 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 Curitiba 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 Curitiba publishes about itself: how the figures here are put together.
