Klipgat, 
South Africa
1,300,816 people lived in Klipgat in 2025. It is the 396th largest of the world's 12,138 cities, and the 5th largest in South Africa.
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.

On the UN's projection it will have 1.7 million people in 2050. It passed a million people between 2010 and 2015. The UN first counts it as a city in 1985, when it passed 50,000 people.
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: South Africa and its 95 cities in 2025, each a dot whose area is its number of people (the largest is Johannesburg). Klipgat 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, Klipgat covered 323 km², and buildings, roads and other built-up land covered 90 km² of it. That is 69 m² of built-up land for each person, about a square 8 by 8 metres. Since 1985, its built-up land has grown to 6.8 times its size, and its people are 18.2 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 South Africa
Its share of South Africa
Of every 100 people in South Africa in 2025, 2 lived in Klipgat, which is 1.3 million people.
How to read this: shrink South Africa to 100 people and this is what you get. The coloured squares are the ones who would live in Klipgat; the grey ones are everybody else, in other cities, in towns and out 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 Klipgat 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 Klipgat publishes about itself: how the figures here are put together.
