Masiu, 
Philippines
63,354 people lived in Masiu in 2010, the last year the UN lists it as a city. After 2010 it is no longer on the list, and the UN does not say whether it fell below 50,000 people or grew into a neighbouring city.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Masiu's own can differ widely. What counts as a city here.

How Masiu grew
Count 10 people in Masiu in 1975 and the same count gives 1.9 in 2010 — the city lost people.
It leaves the UN's list after 2010. The UN's figures for Masiu fall from 334,913 in 1975 to 63,354 in 2010. The UN rates its own confidence in the 1975 figure as moderate: cities are counted from census maps, and where those are old or coarse the figures are least certain.
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 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 Masiu, at its 2010 size; 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 2010, Masiu covered 31 km², and buildings, roads and other built-up land covered 0.5 km² of it.
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 the Philippines
Its share of the Philippines
Of every 1,000 people in the Philippines in 2010, 1 lived in Masiu, which is 63,354 people.
How to read this: 1,000 squares, one for every 1,000th person in the Philippines; the coloured squares live in Masiu. The grey rest live in other cities, in towns or in the countryside.

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 Masiu are the UN's own, at five-year steps: an estimate for each of 1975 to 2010, 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 Masiu publishes about itself: how the figures here are put together.
