Pachuca, 
Mexico
310,805 people lived in Pachuca in 2025. It is the 1846th largest of the world's 12,138 cities, and the 41st largest in Mexico.
Like every city on this site, Pachuca is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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 186 cities in Mexico in 2025, and a dot's area is how many people live there, the biggest being Mexico City. The ringed dot in colour is Pachuca; 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, Pachuca covered 70 km², and buildings, roads and other built-up land covered 20 km² of it. That is 65 m² of built-up land for each person, about a square 8 by 8 metres. Since 1985, its built-up land has grown to 2.5 times its size, and its people are 3.4 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 Mexico
Its share of Mexico
Of every 1,000 people in Mexico in 2025, 2 lived in Pachuca, which is 310,805 people.
How to read this: shrink Mexico to 1,000 people and this is what you get. The coloured squares are the ones who would live in Pachuca; the grey ones are everybody else, in other cities, in towns and out 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 Pachuca are the UN's own, at five-year steps: an estimate for each of 1985 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 Pachuca publishes about itself: how the figures here are put together.
