Casablanca, 
Morocco
4,457,471 people lived in Casablanca in 2025. It is the 94th largest of the world's 12,138 cities, and the largest in Morocco.
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 Casablanca's own can differ widely. What counts as a city here.

How Casablanca grew
For every 10 people in Casablanca in 1975, there were 25.6 in 2025.
On the UN's projection it will have 5.0 million people in 2050.
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.

Casablanca through your family’s years
Put in the years your family were born. You’ll see how many people lived in Casablanca in each of those years, and when each of them turned 30.

Where it is
How to read this: every dot is one of the 73 cities in Morocco in 2025, and a dot's area is how many people live there. The ringed dot in colour is Casablanca; 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, Casablanca covered 411 km², and buildings, roads and other built-up land covered 73 km² of it. That is 16 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 2.3 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.
Of every 100 people in Morocco
Its share of Morocco
Of every 100 people in Morocco in 2025, 12 lived in Casablanca, which is 4.5 million people.
How to read this: 100 squares stand for everyone in Morocco, one square for every 100th person. Count the coloured ones and you have Casablanca's share; the grey remainder live somewhere else 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 Casablanca 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 Casablanca publishes about itself: how the figures here are put together.
