Pekalongan, 
Indonesia
978,519 people lived in Pekalongan in 2025. It is the 528th largest of the world's 12,138 cities, and the 24th 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 Pekalongan'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: 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: 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 Pekalongan; 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, Pekalongan covered 203 km², and buildings, roads and other built-up land covered 30 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 have grown by 21%.
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 1,000 people in Indonesia in 2025, 3 lived in Pekalongan, which is 978,519 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 Pekalongan; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Pekalongan 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 Pekalongan publishes about itself: how the figures here are put together.
