Teresina, 
Brazil
929,795 people lived in Teresina in 2025. It is the 559th largest of the world's 12,138 cities, and the 21st largest in Brazil.
That figure counts the whole built-up area, not the area Teresina 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: 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: 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 Teresina; 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, Teresina covered 184 km², and buildings, roads and other built-up land covered 53 km² of it. That is 57 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 14.7 times its size, and its people are 13.3 times as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in Brazil
Its share of Brazil
Of every 1,000 people in Brazil in 2025, 4 lived in Teresina, which is 929,795 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 Teresina; 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 Teresina 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 Teresina publishes about itself: how the figures here are put together.
