Gagnoa, 
Côte d’Ivoire
219,607 people lived in Gagnoa in 2025. It is the 2693rd largest of the world's 12,138 cities, and the 8th largest in Côte d’Ivoire.
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 Gagnoa's own can differ widely. What counts as a city here.

How Gagnoa grew
Count 10 people in Gagnoa in 1990 and the same count gives 33.7 in 2025.
On the UN's projection it will have 336,650 people in 2050. On the UN's projection it passes 250,000 people between 2030 and 2035. The UN first counts it as a city in 1990, when it passed 50,000 people.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

Where it is
How to read this: every dot is one of the 47 cities in Côte d’Ivoire in 2025, and a dot's area is how many people live there, the biggest being Abidjan. The ringed dot in colour is Gagnoa; 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, Gagnoa covered 36 km², and buildings, roads and other built-up land covered 8.6 km² of it. That is 39 m² of built-up land for each person, about a square 6 by 6 metres. Since 1990, its built-up land has grown to 2 times its size, and its people are 3.4 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.

Its share of Côte d’Ivoire
Of every 1,000 people in Côte d’Ivoire in 2025, 7 lived in Gagnoa, which is 219,607 people.
How to read this: 1,000 squares, one for every 1,000th person in Côte d’Ivoire; the coloured squares live in Gagnoa. 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 Gagnoa are the UN's own, at five-year steps: an estimate for each of 1990 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 Gagnoa publishes about itself: how the figures here are put together.
