Long Xuyên, 
Vietnam
635,490 people lived in Long Xuyên in 2025. It is the 851st largest of the world's 12,138 cities, and the 6th 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 Long Xuyên; 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, Long Xuyên covered 209 km², and buildings, roads and other built-up land covered 28 km² of it. That is 44 m² of built-up land for each person, about a square 7 by 7 metres. Since 1985, its built-up land has grown to 21.5 times its size, and its people are 3.2 times as many.
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 Vietnam
Its share of Vietnam
Of every 1,000 people in Vietnam in 2025, 6 lived in Long Xuyên, which is 635,490 people.
How to read this: 1,000 squares, one for every 1,000th person in Vietnam; the coloured squares live in Long Xuyên. The grey rest live in other cities, in towns or in the countryside.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Long Xuyên 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 Long Xuyên publishes about itself: how the figures here are put together.
