Benin Population Pyramid 2099
Benin in 2099
United Nations projections (medium variant) put the population of Benin at 39,421,860 in 2099. That would be 5.3% more than in 2089 (37,424,139).
The median age is projected at 33.8 years, with 34.2 children under 15 and 18.0 people aged 65 or over for every 100 people of working age (15–64). This is a stationary pyramid — similar numbers in each age group up to the older cohorts, the signature of near-replacement fertility.
