Burundi Population Pyramid 2035
Burundi in 2035
By 2035, the population of Burundi is expected to reach 18,085,841. That would be 25.7% more than in 2025 (14,390,002).
Half of the population would be younger than 20.3 years, with 38.1% children under 15 and 2.7% aged 65 or older. This is an expansive pyramid — each cohort of children is larger than the one above it, the signature of high birth rates and rapid growth.
