Guider, 
Cameroon
187,887 people lived in Guider in 2025. It is the 3214th largest of the world's 12,138 cities, and the 14th largest in Cameroon.
Like every city on this site, Guider is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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: Guider is the dot in colour with a ring around it. The grey dots are the other cities of Cameroon in 2025, 44 in all, led by Yaoundé, 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, Guider covered 22 km², and buildings, roads and other built-up land covered 3.9 km² of it. That is 21 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 2.6 times its size, and its people are 2.7 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 Cameroon
Its share of Cameroon
Of every 1,000 people in Cameroon in 2025, 6 lived in Guider, which is 187,887 people.
How to read this: 1,000 squares, one for every 1,000th person in Cameroon; the coloured squares live in Guider. The grey rest live in other cities, in towns or in the countryside.

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