Generation Alpha & Beta
in Mauritius
How many of each cohort Mauritius has, how fast the next one is arriving, and what the fertility rate, median age and school system mean for both.
Mauritius has approximately 183,900 Generation Alpha people (born 2010–2024), about 14.1% of its population, and roughly 20,068 Generation Beta children born since 2025. Its fertility rate is 1.2 and its child population is shrinking, projected -17% by 2040.
Births since 1 January 2025 at Mauritius's own rate, less infant mortality. At 31 births a day it climbs steadily rather than visibly.
Born 2010–2024 — 14.1% of the population, aged 2–16 this year.
About 31 births a day, all of them Generation Beta.
