Sidfa, 
Egypt
336,659 people lived in Sidfa in 2025. It is the 1697th largest of the world's 12,138 cities, and the 41st largest in Egypt.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Sidfa's own can differ widely. What counts as a city here.

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.

How much land it covers
In 2025, Sidfa covered 73 km², and buildings, roads and other built-up land covered 7.8 km² of it. That is 23 m² of built-up land for each person, about a square 5 by 5 metres. Since 2010, its built-up land has grown to 2.9 times its size, and its people are 2.6 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.

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 Sidfa are the UN's own, at five-year steps: an estimate for each of 2010 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 Sidfa publishes about itself: how the figures here are put together.
