Quảng Ngãi, 
Vietnam
320,907 people lived in Quảng Ngãi in 2025. It is the 1792nd largest of the world's 12,138 cities, and the 15th largest in Vietnam.
Like every city on this site, Quảng Ngãi is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Quảng Ngãi grew

On the UN's projection it will have 281,549 people in 2050. It passed 250,000 people between 2015 and 2020. The UN first counts it as a city in 1980, when it passed 50,000 people.
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: Vietnam and its 137 cities in 2025, each a dot whose area is its number of people (the largest is Ho Chi Minh City). Quảng Ngãi 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, Quảng Ngãi covered 91 km², and buildings, roads and other built-up land covered 14 km² of it. That is 42 m² of built-up land for each person, about a square 6 by 6 metres. Since 1985, its built-up land has grown to 7.5 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 Vietnam
Its share of Vietnam
Of every 1,000 people in Vietnam in 2025, 3 lived in Quảng Ngãi, which is 320,907 people.
How to read this: 1,000 squares stand for everyone in Vietnam, one square for every 1,000th person. Count the coloured ones and you have Quảng Ngãi's share; the grey remainder live somewhere else in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Quảng Ngãi are the UN's own, at five-year steps: an estimate for each of 1980 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 Quảng Ngãi publishes about itself: how the figures here are put together.
