Moshi, 
Tanzania
309,202 people lived in Moshi in 2025. It is the 1861st largest of the world's 12,138 cities, and the 8th largest in Tanzania.
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.

How Moshi grew
Count 10 people in Moshi in 1985 and the same count gives 51.4 in 2025.
On the UN's projection it will have 668,677 people in 2050. It passed 250,000 people between 2015 and 2020. The UN first counts it as a city in 1985, when it passed 50,000 people.

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

Area and built-up land · km²
How much land it covers
In 2025, Moshi covered 68 km², and buildings, roads and other built-up land covered 14 km² of it. That is 44 m² of built-up land for each person, about a square 7 by 7 metres. Since 1985, its built-up land has grown to 4.3 times its size, and its people are 5.1 times as many.
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 Tanzania
Its share of Tanzania
Of every 1,000 people in Tanzania in 2025, 4 lived in Moshi, which is 309,202 people.

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 Moshi are the UN's own, at five-year steps: an estimate for each of 1985 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 Moshi publishes about itself: how the figures here are put together.
