Benin Population Pyramid 2038
Benin in 2038
United Nations projections (medium variant) put the population of Benin at 19,655,275 in 2038. Ten years before, in 2028, the projected population is 15,890,280 — 23.7% lower.
With a projected median age of 21.6 years, Benin would have a youth dependency ratio of 61.2 and an old-age dependency ratio of 6.5 per 100 people of working age. The pyramid is expansive: its wide base of young cohorts reflects high fertility and a rapidly growing population.
