Generation Alpha & Beta
in Colombia
How many of each cohort Colombia has, how fast the next one is arriving, and what the fertility rate, median age and school system mean for both.
Colombia has approximately 11 million Generation Alpha people (born 2010–2024), about 20.8% of its population, and roughly 983,930 Generation Beta children born since 2025. Its fertility rate is 1.6 and its child population is shrinking, projected -22% by 2040.
Births since 1 January 2025 at Colombia's own rate, less infant mortality. At 1,507 births a day it climbs steadily rather than visibly.
Born 2010–2024 — 20.8% of the population, aged 2–16 this year.
About 1,507 births a day, all of them Generation Beta.
Smaller than the Alpha cohort of 11 million.

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

The cohort closes on 31 December 2039; its youngest members enter school here.
School dates follow Colombia's own starting age of 5 and 10 compulsory years, so they differ from the global figures on our Generation Beta page.
