Colima, 
Mexico
295,757 people lived in Colima in 2025. It is the 1960th largest of the world's 12,138 cities, and the 45th largest in Mexico.
Like every city on this site, Colima 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: Colima is the dot in colour with a ring around it. The grey dots are the other cities of Mexico in 2025, 186 in all, led by Mexico City, 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, Colima covered 59 km², and buildings, roads and other built-up land covered 16 km² of it. That is 54 m² of built-up land for each person, about a square 7 by 7 metres. Since 1985, its built-up land has grown to 2.7 times its size, and its people are 3.8 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 Colima, which is 295,757 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 Colima; 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 Colima 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 Colima publishes about itself: how the figures here are put together.
