Oran, 
Algeria
1,192,410 people lived in Oran in 2025. It is the 434th largest of the world's 12,138 cities, and the 2nd largest in Algeria.
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 Oran's own can differ widely. What counts as a city here.

How Oran grew
Count 10 people in Oran in 1975 and the same count gives 26.3 in 2025.
On the UN's projection it will have 1.5 million people in 2050. It passed a million people between 2010 and 2015.

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: Algeria and its 109 cities in 2025, each a dot whose area is its number of people (the largest is Algiers). Oran 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, Oran covered 155 km², and buildings, roads and other built-up land covered 32 km² of it. That is 27 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 3.3 times its size, and its people are 2.6 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 Algeria
Its share of Algeria
Of every 100 people in Algeria in 2025, 3 lived in Oran, which is 1.2 million people.
How to read this: 100 squares, one for every 100th person in Algeria; the coloured squares live in Oran. The grey rest live in other cities, in towns or in the countryside.

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