Unaizah, 
Saudi Arabia
197,665 people lived in Unaizah in 2025. It is the 3025th largest of the world's 12,138 cities, and the 16th largest in Saudi Arabia.
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 Unaizah's own can differ widely. What counts as a city here.

How Unaizah grew

On the UN's projection it will have 348,307 people in 2050. On the UN's projection it passes 250,000 people between 2030 and 2035. The UN first counts it as a city in 1990, when it passed 50,000 people.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: Saudi Arabia and its 44 cities in 2025, each a dot whose area is its number of people (the largest is Riyadh). Unaizah is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Unaizah covered 59 km², and buildings, roads and other built-up land covered 16 km² of it. That is 79 m² of built-up land for each person, about a square 9 by 9 metres. Since 1990, its built-up land has grown to 2 times its size, and its people are 2 times as many.
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 Saudi Arabia
Its share of Saudi Arabia
Of every 1,000 people in Saudi Arabia in 2025, 6 lived in Unaizah, which is 197,665 people.
How to read this: 1,000 squares stand for everyone in Saudi Arabia, one square for every 1,000th person. Count the coloured ones and you have Unaizah's share; the grey remainder live somewhere else in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Unaizah are the UN's own, at five-year steps: an estimate for each of 1990 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 Unaizah publishes about itself: how the figures here are put together.
