Generation Alpha & Beta
in Czechia
How many of each cohort Czechia has, how fast the next one is arriving, and what the fertility rate, median age and school system mean for both.
Czechia has approximately 1.6 million Generation Alpha people (born 2010–2024), about 15.2% of its population, and roughly 149,574 Generation Beta children born since 2025. Its fertility rate is 1.5 and its child population is shrinking, projected -18% by 2040.
Births since 1 January 2025 at Czechia's own rate, less infant mortality. At 228 births a day it climbs steadily rather than visibly.
Born 2010–2024 — 15.2% of the population, aged 2–16 this year.
About 228 births a day, all of them Generation Beta.
