Manaus, 
Brazil
2,277,352 people lived in Manaus in 2025. It is the 217th largest of the world's 12,138 cities, and the 9th largest in Brazil.
That figure counts the whole built-up area, not the area Manaus governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Manaus grew
Where Manaus had 10 people in 1975, it had 68.6 in 2025.
On the UN's projection it will have 2.9 million people in 2050. It passed a million people between 1990 and 1995.
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.

Where it is
How to read this: Manaus 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, Manaus covered 263 km², and buildings, roads and other built-up land covered 82 km² of it. That is 36 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.6 times its size, and its people are 6.9 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 100 people in Brazil in 2025, 1 lived in Manaus, which is 2.3 million people.
How to read this: shrink Brazil to 100 people and this is what you get. The coloured squares are the ones who would live in Manaus; the grey ones are everybody else, in other cities, in towns and out 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 Manaus 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 Manaus publishes about itself: how the figures here are put together.
