Sers Al Layyan, 
Egypt
303,302 people lived in Sers Al Layyan in 2025. It is the 1891st largest of the world's 12,138 cities, and the 48th largest in Egypt.
That figure counts the whole built-up area, not the area Sers Al Layyan governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Sers Al Layyan grew

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 219 cities in Egypt in 2025, and a dot's area is how many people live there, the biggest being Cairo. The ringed dot in colour is Sers Al Layyan; 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, Sers Al Layyan covered 45 km², and buildings, roads and other built-up land covered 7.2 km² of it. That is 24 m² of built-up land for each person, about a square 5 by 5 metres. Since 1985, its built-up land has grown to 6.5 times its size, and its people are 5.2 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 Egypt
Its share of Egypt
Of every 1,000 people in Egypt in 2025, 3 lived in Sers Al Layyan, which is 303,302 people.

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 Sers Al Layyan 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 Sers Al Layyan publishes about itself: how the figures here are put together.
