Xi'an, 
China
5,231,053 people lived in Xi'an in 2025. It is the 77th largest of the world's 12,138 cities, and the 14th largest in China.
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 Xi'an grew
Count 10 people in Xi'an in 1975 and the same count gives 34 in 2025.
On the UN's projection it will have 4.7 million people in 2050. It passed five million people between 2010 and 2015.
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.

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

Where it is
How to read this: China and its 2,082 cities in 2025, each a dot whose area is its number of people (the largest is Shanghai). Xi'an 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, Xi'an covered 622 km², and buildings, roads and other built-up land covered 195 km² of it. That is 37 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 3.2 times its size, and its people are 3.4 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 China
Its share of China
Of every 1,000 people in China in 2025, 4 lived in Xi'an, which is 5.2 million people.
How to read this: shrink China to 1,000 people and this is what you get. The coloured squares are the ones who would live in Xi'an; 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 Xi'an 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 Xi'an publishes about itself: how the figures here are put together.
