Changwon, 
South Korea
665,772 people lived in Changwon in 2025. It is the 814th largest of the world's 12,138 cities, and the 8th largest in South Korea.
That figure counts the whole built-up area, not the area Changwon 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: Changwon is the dot in colour with a ring around it. The grey dots are the other cities of South Korea in 2025, 49 in all, led by Seoul, 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, Changwon covered 109 km², and buildings, roads and other built-up land covered 27 km² of it. That is 40 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown by 72%, and its people are about 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 South Korea
Its share of South Korea
Of every 100 people in South Korea in 2025, 1 lived in Changwon, which is 665,772 people.
How to read this: shrink South Korea to 100 people and this is what you get. The coloured squares are the ones who would live in Changwon; 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 Changwon 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 Changwon publishes about itself: how the figures here are put together.
