Generation Alpha & Beta
in Oceania
Both cohorts across 10 countries, aggregated — with the fertility, schooling and connectivity figures that explain the totals, and the country-by-country detail underneath.
Oceania has approximately 6.2 million Generation Alpha people across 10 profiled countries — about 0.3% of the global cohort — with a population-weighted fertility rate of 1.6 and a median age of 38. Its child population is roughly flat, projected +1.2% by 2040.
0.3% of the global Alpha cohort, across 10 countries.
Smaller than the Alpha cohort of 6.2 million.
All of them Generation Beta.
Median age 38, fertility 1.6.

Oceania against the world average
Regional figures are population-weighted, so a country of 230 million counts for more than one of 5 million. An unweighted average of the same countries would look very different and would mean very little.
