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.

Where it is

Area and built-up land · km²
How much land it covers
In 2025, Erin Woods covered 66 km², and buildings, roads and other built-up land covered 19 km² of it. That is 69 m² of built-up land for each person, about a square 8 by 8 metres. Since 1980, its built-up land has grown to 2.6 times its size, and its people are 3.9 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.

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 Erin Woods are the UN's own, at five-year steps: an estimate for each of 1980 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 Erin Woods publishes about itself: how the figures here are put together.
