Tianjia‘an, 
China
1,100,258 people lived in Tianjia‘an in 2025. It is the 469th largest of the world's 12,138 cities, and the 66th largest in China.
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 Tianjia‘an's own can differ widely. What counts as a city here.

How Tianjia‘an grew
Where Tianjia‘an had 10 people in 1975, it had 27.5 in 2025.
On the UN's projection it will have 1.0 million people in 2050. It passed a million people between 2010 and 2015.
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.

Tianjia‘an through your family’s years
Put in the years your family were born. You’ll see how many people lived in Tianjia‘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). Tianjia‘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, Tianjia‘an covered 143 km², and buildings, roads and other built-up land covered 30 km² of it. That is 27 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 2.7 times its size, and its people are 2.8 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 China
Its share of China
Of every 1,000 people in China in 2025, 1 lived in Tianjia‘an, which is 1.1 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 Tianjia‘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 Tianjia‘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 Tianjia‘an publishes about itself: how the figures here are put together.
