Cuiabá, 
Brazil
798,772 people lived in Cuiabá in 2025. It is the 663rd largest of the world's 12,138 cities, and the 24th largest in Brazil.
That figure counts the whole built-up area, not the area Cuiabá governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Cuiabá grew
Where Cuiabá had 10 people in 1975, it had 141.3 in 2025.
On the UN's projection it will have 937,223 people in 2050. It passed 250,000 people between 1980 and 1985.
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: Cuiabá 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, Cuiabá covered 235 km², and buildings, roads and other built-up land covered 60 km² of it. That is 74 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown to 14.5 times its size, and its people are 14.1 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 1,000 people in Brazil in 2025, 4 lived in Cuiabá, which is 798,772 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 Cuiabá; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Cuiabá 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 Cuiabá publishes about itself: how the figures here are put together.
