Osmaniye, 
Türkiye
286,108 people lived in Osmaniye in 2025. It is the 2034th largest of the world's 12,138 cities, and the 31st largest in Türkiye.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

How Osmaniye grew
Count 10 people in Osmaniye in 1975 and the same count gives 39.7 in 2025.
On the UN's projection it will have 303,731 people in 2050. It passed 250,000 people between 2015 and 2020.
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 177 cities in Türkiye in 2025, and a dot's area is how many people live there, the biggest being Istanbul. The ringed dot in colour is Osmaniye; 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, Osmaniye covered 29 km², and buildings, roads and other built-up land covered 6.8 km² of it. That is 24 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 3.2 times its size, and its people are 4 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.
Of every 100 people in Türkiye
Its share of Türkiye
Of every 1,000 people in Türkiye in 2025, 3 lived in Osmaniye, which is 286,108 people.
How to read this: shrink Türkiye to 1,000 people and this is what you get. The coloured squares are the ones who would live in Osmaniye; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Osmaniye 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 Osmaniye publishes about itself: how the figures here are put together.
