Hải Phòng, 
Vietnam
1,015,494 people lived in Hải Phòng in 2025. It is the 508th largest of the world's 12,138 cities, and the 5th largest in Vietnam.
That figure counts the whole built-up area, not the area Hải Phòng governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Hải Phòng grew
For every 10 people in Hải Phòng in 1975, there were 17.8 in 2025.
On the UN's projection it will have 965,964 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: 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: every dot is one of the 137 cities in Vietnam in 2025, and a dot's area is how many people live there, the biggest being Ho Chi Minh City. The ringed dot in colour is Hải Phòng; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Hải Phòng covered 243 km², and buildings, roads and other built-up land covered 49 km² of it. That is 49 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 6.6 times its size, and its people have grown by 78%.
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 Vietnam
Its share of Vietnam
Of every 100 people in Vietnam in 2025, 1 lived in Hải Phòng, which is 1.0 million people.
How to read this: 100 squares stand for everyone in Vietnam, one square for every 100th person. Count the coloured ones and you have Hải Phòng'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 Hải Phòng 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 Hải Phòng publishes about itself: how the figures here are put together.
