Vanderbijlpark, 
South Africa
257,093 people lived in Vanderbijlpark in 2025. It is the 2275th largest of the world's 12,138 cities, and the 18th largest in South Africa.
That figure counts the whole built-up area, not the area Vanderbijlpark 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: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

Where it is
How to read this: every dot is one of the 95 cities in South Africa in 2025, and a dot's area is how many people live there, the biggest being Johannesburg. The ringed dot in colour is Vanderbijlpark; 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, Vanderbijlpark covered 66 km², and buildings, roads and other built-up land covered 19 km² of it. That is 75 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown to 3 times its size, and its people are 2.5 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 South Africa
Its share of South Africa
Of every 1,000 people in South Africa in 2025, 4 lived in Vanderbijlpark, which is 257,093 people.
How to read this: 1,000 squares stand for everyone in South Africa, one square for every 1,000th person. Count the coloured ones and you have Vanderbijlpark's share; the grey remainder live somewhere else in the country.

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 Vanderbijlpark 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 Vanderbijlpark publishes about itself: how the figures here are put together.
