Tbilisi, 
Georgia
906,746 people lived in Tbilisi in 2025. It is the 571st largest of the world's 12,138 cities, and the largest in Georgia, where it is the capital.
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 Tbilisi's own can differ widely. What counts as a city here.

How Tbilisi grew
Count 10 people in Tbilisi in 1975 and the same count gives 11.1 in 2025.
On the UN's projection it will have 919,861 people in 2050. It passed a million people between 1985 and 1990.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

Tbilisi through your family’s years
Put in the years your family were born. You’ll see how many people lived in Tbilisi in each of those years, and when each of them turned 30.

Where it is
How to read this: Tbilisi is the dot in colour with a ring around it. The grey dots are the other cities of Georgia in 2025, 5 in all, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Tbilisi covered 112 km², and buildings, roads and other built-up land covered 28 km² of it. That is 31 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown by 46%, and its people have grown by 11%.
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 Georgia
Its share of Georgia
Of every 100 people in Georgia in 2025, 24 lived in Tbilisi, which is 906,746 people.
How to read this: 100 squares stand for everyone in Georgia, one square for every 100th person. Count the coloured ones and you have Tbilisi'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 Tbilisi 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 Tbilisi publishes about itself: how the figures here are put together.
