Bata, 
Equatorial Guinea
863,383 people lived in Bata in 2025. It is the 604th largest of the world's 12,138 cities, and the largest in Equatorial Guinea.
That figure counts the whole built-up area, not the area Bata governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Bata grew
Count 10 people in Bata in 1995 and the same count gives 119.3 in 2025.
On the UN's projection it will have 1.4 million people in 2050. On the UN's projection it passes a million people between 2030 and 2035. The UN first counts it as a city in 1995, 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: Bata is the dot in colour with a ring around it. The grey dots are the other cities of Equatorial Guinea in 2025, 2 in all, 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, Bata covered 92 km², and buildings, roads and other built-up land covered 20 km² of it. That is 23 m² of built-up land for each person, about a square 5 by 5 metres. Since 1995, its built-up land has grown to 3.4 times its size, and its people are 11.9 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 Equatorial Guinea
Its share of Equatorial Guinea
Of every 100 people in Equatorial Guinea in 2025, 45 lived in Bata, which is 863,383 people.
How to read this: 100 squares stand for everyone in Equatorial Guinea, one square for every 100th person. Count the coloured ones and you have Bata's share; the grey remainder live somewhere else in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Bata are the UN's own, at five-year steps: an estimate for each of 1995 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 Bata publishes about itself: how the figures here are put together.
