Heroica Nogales, 
Mexico
281,580 people lived in Heroica Nogales in 2025. It is the 2065th largest of the world's 12,138 cities, and the 46th largest in Mexico.
That figure counts the whole built-up area, not the area Heroica Nogales governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

projected (after 2025) · how sure the UN is: high moderate low
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: Mexico and its 186 cities in 2025, each a dot whose area is its number of people (the largest is Mexico City). Heroica Nogales is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Heroica Nogales covered 51 km², and buildings, roads and other built-up land covered 14 km² of it. That is 48 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 5.7 times its size, and its people are 3.7 times as many.
How to read this: pale is the whole of the city's land; the stronger square inside it is what is actually built on. The three are drawn to the same scale, so a larger square really is more land, and hatching means the year is the UN's projection rather than a count.

Its share of Mexico
Of every 1,000 people in Mexico in 2025, 2 lived in Heroica Nogales, which is 281,580 people.

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