Indonesia

Like every city on this site, Jember is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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: Jember 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, Jember covered 96 km², and buildings, roads and other built-up land covered 15 km² of it. That is 29 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 2.1 times its size, and its people have fallen by 7%.
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, 2 lived in Jember, which is 522,844 people.
How to read this: shrink Indonesia to 1,000 people and this is what you get. The coloured squares are the ones who would live in Jember; the grey ones are everybody else, in other cities, in towns and out 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 Jember 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 Jember publishes about itself: how the figures here are put together.
