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 Arraiján'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: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

How much land it covers
In 2025, Arraiján covered 66 km², and buildings, roads and other built-up land covered 13 km² of it. That is 49 m² of built-up land for each person, about a square 7 by 7 metres. Since 1995, its built-up land has grown to 4 times its size, and its people are 3.5 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.

Apparatus
Sources and method
The figures for Arraiján are the UN's own, at five-year steps: an estimate for each of 1995 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 Arraiján publishes about itself: how the figures here are put together.
