Cần Thơ, 
Vietnam
1,327,741 people lived in Cần Thơ in 2025. It is the 384th largest of the world's 12,138 cities, and the 3rd largest in Vietnam.
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.

projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: every dot is one of the 137 cities in Vietnam in 2025, and a dot's area is how many people live there, the biggest being Ho Chi Minh City. The ringed dot in colour is Cần Thơ; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Cần Thơ covered 273 km², and buildings, roads and other built-up land covered 41 km² of it. That is 31 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 37.5 times its size, and its people are 18.7 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.
Of every 100 people in Vietnam
Its share of Vietnam
Of every 100 people in Vietnam in 2025, 1 lived in Cần Thơ, which is 1.3 million people.
How to read this: shrink Vietnam to 100 people and this is what you get. The coloured squares are the ones who would live in Cần Thơ; 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 Cần Thơ 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 Cần Thơ publishes about itself: how the figures here are put together.
