Generation Alpha & Beta
in Belize
How many of each cohort Belize has, how fast the next one is arriving, and what the fertility rate, median age and school system mean for both.
Belize has approximately 112,610 Generation Alpha people (born 2010–2024), about 26.3% of its population, and roughly 13,300 Generation Beta children born since 2025. Its fertility rate is 2 and its child population is shrinking, projected -6% by 2040.
Births since 1 January 2025 at Belize's own rate, less infant mortality. At 20 births a day it climbs steadily rather than visibly.
Born 2010–2024 — 26.3% of the population, aged 2–16 this year.
About 20 births a day, all of them Generation Beta.
Smaller than the Alpha cohort of 112,610.

Key dates for Belize
8 compulsory years from age 5.
Born on 1 January 2025, they reach Belize's starting age of 5.

Eighteen years after the cohort opened.
The cohort closes on 31 December 2039; its youngest members enter school here.
School dates follow Belize's own starting age of 5 and 8 compulsory years, so they differ from the global figures on our Generation Beta page.
