Taichung, 
Taiwan
2,268,685 people lived in Taichung in 2025. It is the 220th largest of the world's 12,138 cities, and the 2nd largest in Taiwan.
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.

Where Taichung had 10 people in 1975, it had 15.3 in 2025.
On the UN's projection it will have 2.0 million people in 2050.
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.

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

Where it is
How to read this: Taiwan and its 21 cities in 2025, each a dot whose area is its number of people (the largest is Taipei). Taichung 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, Taichung covered 309 km², and buildings, roads and other built-up land covered 91 km² of it. That is 40 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 3.3 times its size, and its people have grown by 53%.
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 Taiwan
Its share of Taiwan
Of every 100 people in Taiwan in 2025, 10 lived in Taichung, which is 2.3 million people.
How to read this: 100 squares stand for everyone in Taiwan, one square for every 100th person. Count the coloured ones and you have Taichung's share; the grey remainder live somewhere else 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 Taichung 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 Taichung publishes about itself: how the figures here are put together.
