Londrina, 
Brazil
598,731 people lived in Londrina in 2025. It is the 910th largest of the world's 12,138 cities, and the 29th largest in Brazil.
That figure counts the whole built-up area, not the area Londrina governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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: every dot is one of the 356 cities in Brazil in 2025, and a dot's area is how many people live there, the biggest being São Paulo. The ringed dot in colour is Londrina; 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, Londrina covered 139 km², and buildings, roads and other built-up land covered 42 km² of it. That is 70 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 3.3 times its size, and its people are 3.2 times as many.
How to read this: the outer pale square stands for all the land the city covers, and the solid square inside it for the part with buildings, roads and the like on it. All three squares share a scale, so you can compare them by eye. A hatched one is a year the UN has projected.
Of every 100 people in Brazil
Its share of Brazil
Of every 1,000 people in Brazil in 2025, 3 lived in Londrina, which is 598,731 people.
How to read this: shrink Brazil to 1,000 people and this is what you get. The coloured squares are the ones who would live in Londrina; 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 Londrina 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 Londrina publishes about itself: how the figures here are put together.
