Generation Alpha & Beta
in Benin
How many of each cohort Benin has, how fast the next one is arriving, and what the fertility rate, median age and school system mean for both.
Benin has approximately 6.3 million Generation Alpha people (born 2010–2024), about 41.4% of its population, and roughly 861,173 Generation Beta children born since 2025. Its fertility rate is 4.3 and its child population is growing, projected +18% by 2040.
Births since 1 January 2025 at Benin's own rate, less infant mortality. At 1,354 births a day it climbs steadily rather than visibly.
Born 2010–2024 — 41.4% of the population, aged 2–16 this year.
About 1,354 births a day, all of them Generation Beta.
Larger than the Alpha cohort — one of the countries where the next generation grows.

The cohort closes on 31 December 2039; its youngest members enter school here.
School dates follow Benin's own starting age of 6 and 6 compulsory years, so they differ from the global figures on our Generation Beta page.
