Benin Population Pyramid 2034
Benin in 2034
In 2034, Benin is projected to have a population of 18,109,913 people. Ten years before, in 2024, the projected population is 14,462,724 — 25.2% lower.
Half of the population would be younger than 20.7 years, with 37.8% children under 15 and 3.6% 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.
