Iligan, 
Philippines
341,172 people lived in Iligan in 2025. It is the 1676th largest of the world's 12,138 cities, and the 14th largest in the Philippines.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

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: Iligan is the dot in colour with a ring around it. The grey dots are the other cities of the Philippines in 2025, 114 in all, led by Manila, 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, Iligan covered 74 km², and buildings, roads and other built-up land covered 7.2 km² of it. That is 21 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 3.4 times its size, and its people are 5.5 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.
Of every 100 people in the Philippines
Its share of the Philippines
Of every 1,000 people in the Philippines in 2025, 3 lived in Iligan, which is 341,172 people.
How to read this: shrink the Philippines to 1,000 people and this is what you get. The coloured squares are the ones who would live in Iligan; the grey ones are everybody else, in other cities, in towns and out in the country.

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