Benin Population Pyramid 2040
Benin in 2040
By 2040, the population of Benin is expected to reach 20,445,760. Compared with 2030, when the projection stands at 16,618,822, that represents growth of 23.0% over ten years.
Half of the population would be younger than 22.0 years, with 35.9% children under 15 and 4.0% 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.
