Boumerdes, 
Algeria
550,700 people lived in Boumerdes in 2025. It is the 998th largest of the world's 12,138 cities, and the 4th largest in Algeria.
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 Boumerdes grew

On the UN's projection it will have 704,637 people in 2050. It passed 250,000 people between 2005 and 2010. 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: 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: Boumerdes is the dot in colour with a ring around it. The grey dots are the other cities of Algeria in 2025, 109 in all, led by Algiers, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Boumerdes covered 162 km², and buildings, roads and other built-up land covered 31 km² of it. That is 56 m² of built-up land for each person, about a square 8 by 8 metres. Since 1985, its built-up land has grown to 8.2 times its size, and its people are 9.8 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 Algeria
Its share of Algeria
Of every 100 people in Algeria in 2025, 1 lived in Boumerdes, which is 550,700 people.
How to read this: shrink Algeria to 100 people and this is what you get. The coloured squares are the ones who would live in Boumerdes; 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 Boumerdes 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 Boumerdes publishes about itself: how the figures here are put together.
