Jakarta, 
Indonesia
41,913,860 people lived in Jakarta in 2025. It is the 1st largest of the world's 12,138 cities, and the largest in Indonesia, where it is the capital.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

How Jakarta grew
For every 10 people in Jakarta in 1975, there were 35.8 in 2025.
On the UN's projection it will have 51.8 million people in 2050.
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.

Jakarta through your family’s years
Put in the years your family were born. You’ll see how many people lived in Jakarta in each of those years, and when each of them turned 30.
Indonesia · every city · 2025
Where it is
How to read this: every dot is one of the 389 cities in Indonesia in 2025, and a dot's area is how many people live there. The ringed dot in colour is Jakarta; 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, Jakarta covered 4,883 km², and buildings, roads and other built-up land covered 1,162 km² of it. That is 28 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 2.7 times its size, and its people are 3.6 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 Indonesia
Its share of Indonesia
Of every 100 people in Indonesia in 2025, 15 lived in Jakarta, which is 41.9 million people.
How to read this: 100 squares stand for everyone in Indonesia, one square for every 100th person. Count the coloured ones and you have Jakarta'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 Jakarta 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 Jakarta publishes about itself: how the figures here are put together.
