Concepción, 
Chile
516,741 people lived in Concepción in 2025. It is the 1075th largest of the world's 12,138 cities, and the 3rd largest in Chile.
That figure counts the whole built-up area, not the area Concepción governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Concepción grew
Count 10 people in Concepción in 1975 and the same count gives 14.9 in 2025.
On the UN's projection it will have 519,845 people in 2050.
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: Concepción is the dot in colour with a ring around it. The grey dots are the other cities of Chile in 2025, 36 in all, led by Santiago, 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, Concepción covered 102 km², and buildings, roads and other built-up land covered 22 km² of it. That is 43 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 2.1 times its size, and its people have grown by 49%.
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.
Of every 100 people in Chile
Its share of Chile
Of every 100 people in Chile in 2025, 3 lived in Concepción, which is 516,741 people.
How to read this: shrink Chile to 100 people and this is what you get. The coloured squares are the ones who would live in Concepción; 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 Concepción 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 Concepción publishes about itself: how the figures here are put together.
