Aguascalientes, 
Mexico
856,387 people lived in Aguascalientes in 2025. It is the 611th largest of the world's 12,138 cities, and the 12th largest in Mexico.
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.

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

Area and built-up land · km²
How much land it covers
In 2025, Aguascalientes covered 137 km², and buildings, roads and other built-up land covered 42 km² of it. That is 49 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 3 times its size, and its people are 5.5 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.

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 Aguascalientes 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 Aguascalientes publishes about itself: how the figures here are put together.
