Generation Alpha & Beta
in Nauru
How many of each cohort Nauru has, how fast the next one is arriving, and what the fertility rate, median age and school system mean for both.
Nauru has approximately 4,500 Generation Alpha people (born 2010–2024), about 37.2% of its population, and roughly 500 Generation Beta children born since 2025. Its fertility rate is 3.2 and its child population is roughly flat, projected -1% by 2040.
Births since 1 January 2025 at Nauru's own rate, less infant mortality. At 1 births a day it climbs steadily rather than visibly.
Born 2010–2024 — 37.2% of the population, aged 2–16 this year.
About 1 births a day, all of them Generation Beta.
Larger than the Alpha cohort — one of the countries where the next generation grows.

Key dates for Nauru
14 compulsory years from age 6.
Born on 1 January 2025, they reach Nauru's starting age of 6.
Under-15s change by −1% against today.
Eighteen years after the cohort opened.
The cohort closes on 31 December 2039; its youngest members enter school here.
School dates follow Nauru's own starting age of 6 and 14 compulsory years, so they differ from the global figures on our Generation Beta page.
