San Pablo, 
Philippines
276,250 people lived in San Pablo in 2025. It is the 2101st largest of the world's 12,138 cities, and the 21st largest in the Philippines.
Like every city on this site, San Pablo is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How San Pablo grew
Count 10 people in San Pablo in 1990 and the same count gives 40.2 in 2025.
On the UN's projection it will have 345,082 people in 2050. It passed 250,000 people between 2020 and 2025. The UN first counts it as a city in 1990, 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: every dot is one of the 114 cities in the Philippines in 2025, and a dot's area is how many people live there, the biggest being Manila. The ringed dot in colour is San Pablo; 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, San Pablo covered 69 km², and buildings, roads and other built-up land covered 6.6 km² of it. That is 24 m² of built-up land for each person, about a square 5 by 5 metres. Since 1990, its built-up land has grown to 3.7 times its size, and its people are 4 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 the Philippines
Its share of the Philippines
Of every 1,000 people in the Philippines in 2025, 2 lived in San Pablo, which is 276,250 people.

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 San Pablo are the UN's own, at five-year steps: an estimate for each of 1990 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 San Pablo publishes about itself: how the figures here are put together.
