Quito, 
Ecuador
2,534,914 people lived in Quito in 2025. It is the 197th largest of the world's 12,138 cities, and the 2nd largest in Ecuador, where it is the capital.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

How Quito grew
Where Quito had 10 people in 1975, it had 39.8 in 2025.
On the UN's projection it will have 2.9 million people in 2050. It passed a million people between 1980 and 1985.

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.

Quito through your family’s years
Put in the years your family were born. You’ll see how many people lived in Quito in each of those years, and when each of them turned 30.

Where it is
How to read this: every dot is one of the 32 cities in Ecuador in 2025, and a dot's area is how many people live there, the biggest being Guayaquil. The ringed dot in colour is Quito; 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, Quito covered 383 km², and buildings, roads and other built-up land covered 103 km² of it. That is 41 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.4 times its size, and its people are 4 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 Ecuador
Its share of Ecuador
Of every 100 people in Ecuador in 2025, 14 lived in Quito, which is 2.5 million people.
How to read this: 100 squares stand for everyone in Ecuador, one square for every 100th person. Count the coloured ones and you have Quito's share; the grey remainder live somewhere else 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 Quito 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 Quito publishes about itself: how the figures here are put together.
