Ciudad Obregón, 
Mexico
326,226 people lived in Ciudad Obregón in 2025. It is the 1760th largest of the world's 12,138 cities, and the 38th largest in Mexico.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Ciudad Obregón's own can differ widely. What counts as a city here.

Area and built-up land · km²
How much land it covers
In 2025, Ciudad Obregón covered 65 km², and buildings, roads and other built-up land covered 19 km² of it. That is 59 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 3.1 times its size, and its people are 2.5 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.

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