Benin Population Pyramid 2100
Benin in 2100
By 2100, the population of Benin is expected to reach 39,587,568. Compared with 2090, when the projection stands at 37,651,973, that represents growth of 5.1% over ten years.
With a projected median age of 34.0 years, Benin would have a youth dependency ratio of 34.0 and an old-age dependency ratio of 18.3 per 100 people of working age. The pyramid is stationary: cohort sizes are roughly even through the younger ages, reflecting fertility close to replacement level and slow population change.
