Burundi has somewhere over 14 million people living in 27,834 square kilometres. That is a country the size of Belgium with a population approaching Belgium's own, almost none of it in cities — and it explains more about the place than any other single fact.
The numbers
- Population: around 14 million, depending on whose estimate you take. Figures between 13 and 15 million are all defensible; the last full census is old and projections differ.
- Area: 27,834 km².
- Density: over 500 people per square kilometre — among the highest in Africa.
- Urban: roughly one person in seven. Burundi is one of the least urbanised countries in the world.
- Median age: under twenty. Half the country is younger than that.
What that looks like on the ground
Visitors arriving from Europe expect "dense" to mean apartment blocks. Here it means the opposite: the population is spread almost evenly across the hills, in homesteads surrounded by their own fields rather than gathered into villages. Drive anywhere outside the capital and there is no empty stretch — houses, banana groves and cultivated terraces run continuously over every ridge, right up to the edge of the forests.
It also means the roads are full of people on foot: carrying water, bananas, charcoal, bricks. Give yourself longer for every journey, and expect your driver to be constantly easing past pedestrians.
The cities
Bujumbura is the economic capital and much the largest city, somewhere around a million people, laid out along the lake and climbing into the hills behind.
Gitega, the political capital since 2019, is far smaller — a calm highland town rather than a metropolis, which surprises people expecting a capital city.
After those two, the towns are modest: Ngozi, Rumonge, Muyinga, Kayanza. Most of Burundi lives outside all of them.
A very young country
The thing you notice within an hour of arriving is the children — everywhere, in enormous numbers, walking to school in uniform in the morning and back in the afternoon. With a median age under twenty, that is simply what the population looks like.
It also shapes everything else: pressure on land as farms are divided between sons, pressure on schools, and a steady movement of young people towards Bujumbura looking for work that doesn't involve a hoe.
Who lives here
Burundians belong to three groups — Hutu, Tutsi and Twa — who share one language, Kirundi, spoken by essentially everyone, and live across the same hills rather than in separate regions. The three stars on the national flag stand for them.
The country's recent history around those identities is painful and recent, and it is not dinner-table conversation for a visitor. Ask about the hills, the harvest, football, music. If someone chooses to tell you their own story, listen carefully.
Land, and why it matters
Roughly nine people in ten live from farming, on plots that get smaller with each generation. That is the central economic fact of Burundi: very many people, very little land, and extraordinary skill at making the little land produce.
Once you have seen a hillside terraced to its summit — beans under bananas, coffee on the slope, cassava at the edge — the density stops being a statistic and starts looking like the achievement it is.
