Gen Beta Population Statistics (2026)
The size, growth rate and projected trajectory of Generation Beta — the cohort born from 2025.
Generation Beta currently numbers approximately 241.8 million people and is growing by about 4.2 births per second. It is projected to reach 2.1 billion and roughly 16% of the world population by 2035.

What is modelled and what is measured
The current population figure is modelled: we take a published estimate of births since 1 January 2025, apply infant and child mortality rates, and advance the number continuously.
The projections to 2039 come from applying UN medium-variant fertility assumptions to the cohort window. They are projections, not measurements, and fertility has consistently undershot UN medium projections for the last decade.
Frequently asked
How many Gen Beta are there right now?

How big will Generation Beta be?
Projected at about 2.1 billion by the time the cohort closes in 2039.
When does Generation Beta end?
31 December 2039. Anyone born after that belongs to the next, as-yet-unnamed generation.
