Tây Ninh, 
Vietnam
437,816 people lived in Tây Ninh in 2025. It is the 1273rd largest of the world's 12,138 cities, and the 10th 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.

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: Vietnam and its 137 cities in 2025, each a dot whose area is its number of people (the largest is Ho Chi Minh City). Tây Ninh is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Tây Ninh covered 103 km², and buildings, roads and other built-up land covered 23 km² of it. That is 53 m² of built-up land for each person, about a square 7 by 7 metres. Since 1985, its built-up land has grown to 17.9 times its size, and its people are 5.2 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 Vietnam
Its share of Vietnam
Of every 1,000 people in Vietnam in 2025, 4 lived in Tây Ninh, which is 437,816 people.
How to read this: shrink Vietnam to 1,000 people and this is what you get. The coloured squares are the ones who would live in Tây Ninh; 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 Tây Ninh are the UN's own, at five-year steps: an estimate for each of 1985 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 Tây Ninh publishes about itself: how the figures here are put together.
