Indonesia

Like every city on this site, Slawi 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: every dot is one of the 389 cities in Indonesia in 2025, and a dot's area is how many people live there, the biggest being Jakarta. The ringed dot in colour is Slawi; 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, Slawi covered 460 km², and buildings, roads and other built-up land covered 56 km² of it. That is 32 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 times its size, and its people have grown by 32%.
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, 6 lived in Slawi, which is 1.7 million people.
How to read this: 1,000 squares, one for every 1,000th person in Indonesia; the coloured squares live in Slawi. The grey rest live in other cities, in towns or in the countryside.

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 Slawi 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 Slawi publishes about itself: how the figures here are put together.
