Jambi, 
Indonesia
980,534 people lived in Jambi in 2025. It is the 525th largest of the world's 12,138 cities, and the 23rd largest in Indonesia.
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 Jambi's own can differ widely. What counts as a city here.

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.

Where it is
How to read this: Jambi is the dot in colour with a ring around it. The grey dots are the other cities of Indonesia in 2025, 389 in all, led by Jakarta, 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, Jambi covered 141 km², and buildings, roads and other built-up land covered 31 km² of it. That is 31 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.4 times its size, and its people are 3.6 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.
Of every 100 people in Indonesia
Its share of Indonesia
Of every 1,000 people in Indonesia in 2025, 3 lived in Jambi, which is 980,534 people.
How to read this: 1,000 squares stand for everyone in Indonesia, one square for every 1,000th person. Count the coloured ones and you have Jambi'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 Jambi 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 Jambi publishes about itself: how the figures here are put together.
