Generation Alpha & Beta
in Marshall Islands
How many of each cohort Marshall Islands has, how fast the next one is arriving, and what the fertility rate, median age and school system mean for both.
Marshall Islands has approximately 11,890 Generation Alpha people (born 2010–2024), about 33.9% of its population, and roughly 1,200 Generation Beta children born since 2025. Its fertility rate is 2.8 and its child population is shrinking, projected -37% by 2040.
Births since 1 January 2025 at Marshall Islands's own rate, less infant mortality. At 2 births a day it climbs steadily rather than visibly.
Born 2010–2024 — 33.9% of the population, aged 2–16 this year.
About 2 births a day, all of them Generation Beta.
Smaller than the Alpha cohort of 11,890.

Key dates for Marshall Islands
13 compulsory years from age 6.
Born on 1 January 2025, they reach Marshall Islands's starting age of 6.
