Lucapa, 
Angola
141,466 people lived in Lucapa in 2025. It is the 4307th largest of the world's 12,138 cities, and the 25th largest in Angola.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

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 57 cities in Angola in 2025, and a dot's area is how many people live there, the biggest being Luanda. The ringed dot in colour is Lucapa; 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, Lucapa covered 21 km², and buildings, roads and other built-up land covered 4.6 km² of it. That is 33 m² of built-up land for each person, about a square 6 by 6 metres. Since 2005, its built-up land has grown to 3.3 times its size, and its people are 2 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 Angola
Its share of Angola
Of every 1,000 people in Angola in 2025, 4 lived in Lucapa, which is 141,466 people.
How to read this: shrink Angola to 1,000 people and this is what you get. The coloured squares are the ones who would live in Lucapa; the grey ones are everybody else, in other cities, in towns and out in the country.

Apparatus
Sources and method
The figures for Lucapa are the UN's own, at five-year steps: an estimate for each of 2005 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 Lucapa publishes about itself: how the figures here are put together.
