Cagayan de Oro, 
Philippines
870,291 people lived in Cagayan de Oro in 2025. It is the 601st largest of the world's 12,138 cities, and the 6th largest in the Philippines.
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 Cagayan de Oro's own can differ widely. What counts as a city here.

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

Area and built-up land · km²
How much land it covers
In 2025, Cagayan de Oro covered 125 km², and buildings, roads and other built-up land covered 19 km² of it. That is 22 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 2.9 times its size, and its people are 7 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.

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 Cagayan de Oro 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 Cagayan de Oro publishes about itself: how the figures here are put together.
