projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: Saltillo 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, Saltillo covered 144 km², and buildings, roads and other built-up land covered 42 km² of it. That is 56 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 3.6 times its size, and its people are 4.4 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 Mexico
Its share of Mexico
Of every 1,000 people in Mexico in 2025, 6 lived in Saltillo, which is 737,662 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 Saltillo; 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 Saltillo 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 Saltillo publishes about itself: how the figures here are put together.
