Blumenau, 
Brazil
234,982 people lived in Blumenau in 2025. It is the 2495th largest of the world's 12,138 cities, and the 72nd 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 Blumenau's own can differ widely. What counts as a city here.

How Blumenau grew
Where Blumenau had 10 people in 1990, it had 32.4 in 2025.
On the UN's projection it will have 345,289 people in 2050. On the UN's projection it passes 250,000 people between 2025 and 2030. The UN first counts it as a city in 1990, when it passed 50,000 people.
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.

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 Blumenau; 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, Blumenau covered 81 km², and buildings, roads and other built-up land covered 16 km² of it. That is 67 m² of built-up land for each person, about a square 8 by 8 metres. Since 1990, its built-up land has grown to 2.8 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, 1 lived in Blumenau, which is 234,982 people.
How to read this: 1,000 squares stand for everyone in Brazil, one square for every 1,000th person. Count the coloured ones and you have Blumenau'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 Blumenau are the UN's own, at five-year steps: an estimate for each of 1990 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 Blumenau publishes about itself: how the figures here are put together.
