Bi'r Rubak, 
Yemen
712,438 people lived in Bi'r Rubak in 2025. It is the 754th largest of the world's 12,138 cities, and the 5th largest in Yemen.
That figure counts the whole built-up area, not the area Bi'r Rubak governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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 111 cities in Yemen in 2025, and a dot's area is how many people live there, the biggest being Sana'a. The ringed dot in colour is Bi'r Rubak; 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, Bi'r Rubak covered 56 km², and buildings, roads and other built-up land covered 8.4 km² of it. That is 12 m² of built-up land for each person, about a square 3 by 3 metres. Since 1975, its built-up land has grown to 3.5 times its size, and its people are 5.2 times as many.
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 Yemen
Its share of Yemen
Of every 100 people in Yemen in 2025, 2 lived in Bi'r Rubak, which is 712,438 people.
How to read this: 100 squares stand for everyone in Yemen, one square for every 100th person. Count the coloured ones and you have Bi'r Rubak's share; the grey remainder live somewhere else 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 Bi'r Rubak 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 Bi'r Rubak publishes about itself: how the figures here are put together.
