Jombang, 
Indonesia
478,051 people lived in Jombang in 2025. It is the 1160th largest of the world's 12,138 cities, and the 44th largest in Indonesia.
That figure counts the whole built-up area, not the area Jombang governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

projected (after 2025) · how sure the UN is: high moderate low
How to read this: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

Where it is
How to read this: Indonesia and its 389 cities in 2025, each a dot whose area is its number of people (the largest is Jakarta). Jombang is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Jombang covered 130 km², and buildings, roads and other built-up land covered 18 km² of it. That is 38 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 3.7 times its size, and its people have grown by 88%.
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 Jombang, which is 478,051 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 Jombang; 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 Jombang 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 Jombang publishes about itself: how the figures here are put together.
