Nha Trang, 
Vietnam
503,051 people lived in Nha Trang in 2025. It is the 1099th largest of the world's 12,138 cities, and the 8th largest in Vietnam.
Like every city on this site, Nha Trang is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Nha Trang grew
For every 10 people in Nha Trang in 1975, there were 25.9 in 2025.

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.

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). Nha Trang 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, Nha Trang covered 104 km², and buildings, roads and other built-up land covered 22 km² of it. That is 43 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 6.2 times its size, and its people are 2.6 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 Vietnam
Its share of Vietnam
Of every 1,000 people in Vietnam in 2025, 5 lived in Nha Trang, which is 503,051 people.
How to read this: shrink Vietnam to 1,000 people and this is what you get. The coloured squares are the ones who would live in Nha Trang; the grey ones are everybody else, in other cities, in towns and out 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 Nha Trang 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 Nha Trang publishes about itself: how the figures here are put together.
