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
How to read this: every dot is one of the 259 cities in Ethiopia in 2025, and a dot's area is how many people live there, the biggest being Addis Ababa. The ringed dot in colour is Irba; 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, Irba covered 24 km², and buildings, roads and other built-up land covered 1.0 km² of it. That is 9 m² of built-up land for each person, about a square 3 by 3 metres.
How to read this: the outer pale square stands for all the land the city covers, and the solid square inside it for the part with buildings, roads and the like on it. All three squares share a scale, so you can compare them by eye. A hatched one is a year the UN has projected.
Of every 100 people in Ethiopia
Its share of Ethiopia
Of every 1,000 people in Ethiopia in 2025, 1 lived in Irba, which is 112,673 people.
How to read this: shrink Ethiopia to 1,000 people and this is what you get. The coloured squares are the ones who would live in Irba; 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 Irba are the UN's own, at five-year steps: an estimate for each of 2010 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 Irba publishes about itself: how the figures here are put together.
